Building the WebLock UI
as you can see, weblock is initialized as a global javascript variable, available in the scope of these functions and others: var weblock = components.classes["@dougt/weblock"] .getservice() .queryinterface(components.interfaces.iweblock); in addition to this basic setup, you must also write javascript that uses the addsite method to add new sites to the white list.
...in this tutorial, focusing as it is on the weblock functionality (rather than the ui), we'll assume the strings we get from the ui itself are urls we actually want to write to the white list: function addthissite() { var tf = document.getelementbyid("dialog.input"); // weblock is global and declared above weblock.addsite(tf.value); } this javascript function can be called directly from the xul widget, where the input string is retrieved as the value property of the textbox element.

Content Scripts - Archive of obsolete content
there are five basic principles: the add-on's main code, including "main.js" and other modules in "lib", can use the sdk high-level and low-level apis, but can't access web content directly content scripts can't use the sdk's apis (no access to globals exports, require) but can access web content sdk apis that use content scripts, like page-mod and tabs, provide functions that enable the add-on's main code to load content scripts into web pages content scripts can be loaded in as strings, but are more often stored as separate files under the add-on's "data" directory.
... for example, this content script will fail with the error "themessage is not defined": var themessage = "hello from content script!"; anelement.setattribute("onclick", "alert(themessage);"); second, if you define an event listener by direct assignment to a global event handler like onclick, then the assignment might be overridden by the page.
... accessing port in the content script in the content script the port object is available as a property of the global self object.
... so to emit a message from a content script: self.port.emit("mycontentscriptmessage", mycontentscriptmessagepayload); to receive a message from the add-on code: self.port.on("myaddonmessage", function(myaddonmessagepayload) { // handle the message }); note that the global self object is completely different from the self module, which provides an api for an add-on to access its data files and id.

Java in Firefox Extensions - Archive of obsolete content
note: the global java object has been removed in gecko 16.0, so this page is out of date.
...liveconnect gives your extension's javascript code (linked from or contained in xul code) access to 2 objects: java and packages (note that per this thread, although the new documentation for the liveconnect reimplementation states that these globals will be deprecated (in the context of applets), "firefox and the java plug-in will continue to support the global java/packages keywords, in particular in the context of firefox extensions.").
...one example seems to be the fact that the "java" global is not immediately available if the extension operates in a sidebar (using settimeout solved it at least).
...i've also experienced crashes in referencing the 'java' global within the xul editor of the extension developer's extension which seems to point to some stability problem.

A XUL Bestiary - Archive of obsolete content
the chrome url, which appears in place of the http url in pointers like the following global skin processing instruction: <?xml-stylesheet href="chrome://global/skin/" type="text/css"?> specifies a chrome to be loaded by the gecko rendering engine.
...in other words, a chrome url like the global pointer above picks up a file called global.css, and the help pointer above could also be written as chrome://help/content, because the name of the package itself is "help." viewing chromes other than mozilla's there is a special flag you can use to start mozilla with some chrome other than the default.
...even prior to the skinning that takes place with the global skin, which is loaded in almost every xul file you see in mozilla (and whose absence from your own xul files can make your work look strange, senseless, or invisible altogether), a xul.css file is loaded which provides some very basic presentational information for the widgets in the toolkit.

Working with Svelte stores - Learn web development
stores are global global data repositories that hold values.
...in that case, moving to a global data store might be a good option.
... the end result of this nifty trick is that you can access global stores just as easily as using reactive local variables.
...you will get something like this: svelte stores provide a very simple and lightweight, but extremely powerful, way to handle complex app state from a global data store in a reactive way.

Mozilla accessibility architecture
three levels of the accessibility cache there are three levels in the accessibility cache: global cache of doc accessibles (gglobaldocaccessiblecache), used to get the accessible for any document.
...we must first get the document accessible from the global cache for the node's document, and then use that document accessible's specific cache to check for an entry for the dom node.
...the weak pres shell is used to create a hash key to get the doc accessible from gglobaldocaccessiblecache.
... at program shutdown, when the nsaccessibilityservice observes ns_xpcom_shutdown_observer_id, it iterates through the doc accessibles in gglobaldocaccessiblecache and destroys all of the doc accessibles them.

Creating Sandboxed HTTP Connections

...since the channel that causes the notification is passed in as the first argument, comparing it to the globally stored channel (gchannel) in the previous section (which also gets updated each time a redirect happens).

Communicating with frame scripts
asynchronous messaging to send an asynchronous message the frame script uses the global sendasyncmessage() function: // frame script sendasyncmessage("my-addon@me.org:my-e10s-extension-message"); sendasyncmessage() takes one mandatory parameter, which is the name of the message.
... synchronous messaging to send a synchronous message, the frame script uses the global sendsyncmessage() function: // frame script sendsyncmessage("my-addon@me.org:my-e10s-extension-message"); when a chrome script receives a synchronous message, it should return a value from its message listener: // chrome script messagemanager.addmessagelistener("my-addon@me.org:my-e10s-extension-message", listener); function listener(message) { return "value from chrome"; } this value is t...
...if it's a browser message manager, you can use the message manager's sendasyncmessage method: // chrome script browser.messagemanager.sendasyncmessage("my-addon@me.org:message-from-chrome"); if you have a window or a global message manager, you need to use the broadcastasyncmessage method: // chrome script window.messagemanager.broadcastasyncmessage("my-addon@me.org:message-from-chrome"); these methods takes one mandatory parameter, which is the message name.
... after the message name, you can pass detailed data as a string or a json-serializable object: // chrome script messagemanager.sendasyncmessage("my-addon@me.org:message-from-chrome", { details : "some more details" }); to receive a message from chrome, a frame script uses the global addmessagelistener() function.

Process scripts
for example, if you call the global frame message manager's loadframescript() function, then the script will be loaded separately into all open tabs.
... this can then cause a problem the frame scripts are interacting with a global service in the content process.
...the following code uses the global parent process message manager, which will load the script into the the chrome process and any child processes: // chrome code let ppmm = cc["@mozilla.org/parentprocessmessagemanager;1"] .getservice(ci.nsiprocessscriptloader); ppmm.loadprocessscript("chrome://whatever/process-script.js", true); ppmm.addmessagelistener("hello", function(msg) { ...
... }); the process script's global is a child process message manager, which enables the process script to receive messages from the chrome side, and to send messages to the chrome side: // process-script.js if (services.appinfo.processtype == services.appinfo.process_type_content) { dump("welcome to the process script in a content process"); } else { dump("welcome to the process script in the main process"); } // message is sent using contentprocessmessagemanager sendasyncmessage("hello"); in this example, the dump() statement will run once in each content process as well as in the main process.

Functions
since it will never need to walk the scope chain, its parent is the global object.
...the function object's parent is the global object.
...outside all functions, if a name definitely refers to a global for which we have seen a var, const, or function declaration, then we emit a js_defvar instruction in the script prelude and access the global using jsop_{get,set,call}gvar.
... this is fast if the global either doesn't exist before the script runs (the script creates it) or it's a non-configurable data property (which amounts to the same thing).

XUL Overlays
note: the master skin is not the same as the global skin.

Debugger-API - Firefox Developer Tools
environments may belong to a running stack frame, captured by a function closure, or reflect some global object’s properties as variables.
... the debugger instance itself is not really a shadow of anything in the debuggee; rather, it maintains the set of global objects which are to be considered debuggees.
... a debugger observes only execution taking place in the scope of these global objects.
... gecko-specific features while the debugger core api deals only with concepts common to any javascript implementation, it also includes some gecko-specific features: [global tracking][global] supports debugging all the code running in a gecko instance at once—the ‘chrome debugging’ model.

CanvasRenderingContext2D - Web APIs
compositing canvasrenderingcontext2d.globalalpha alpha value that is applied to shapes and images before they are composited onto the canvas.
... canvasrenderingcontext2d.globalcompositeoperation with globalalpha applied this sets how shapes and images are drawn onto the existing bitmap.
... canvasrenderingcontext2d.setalpha() use canvasrenderingcontext2d.globalalpha instead.
... canvasrenderingcontext2d.setcompositeoperation() use canvasrenderingcontext2d.globalcompositeoperation instead.

Compositing and clipping - Web APIs
we can, however, change this behaviour by setting the globalcompositeoperation property.
... globalcompositeoperation we can not only draw new shapes behind existing shapes but we can also use it to mask off certain areas, clear sections from the canvas (not limited to rectangles like the clearrect() method does) and more.
... globalcompositeoperation = type this sets the type of compositing operation to apply when drawing new shapes, where type is a string identifying which of the twelve compositing operations to use.
... if we compare clipping paths to the globalcompositeoperation property we've seen above, we see two compositing modes that achieve more or less the same effect in source-in and source-atop.

Introduction to the File and Directory Entries API - Web APIs
global methods of the asynchronous and synchronous apis.
... the asynchronous api has the following global methods: requestfilesystem() and resolvelocalfilesystemurl().
... these methods are members of both the window object and the worker global scope.
...these synchronous methods are members of the worker's global scope only, not the window object.

Pinch zoom gestures - Web APIs

WebGLRenderingContext.getUniformLocation() - Web APIs
gl.useprogram(shaderprogram); uscalingfactor = gl.getuniformlocation(shaderprogram, "uscalingfactor"); uglobalcolor = gl.getuniformlocation(shaderprogram, "uglobalcolor"); urotationvector = gl.getuniformlocation(shaderprogram, "urotationvector") gl.uniform2fv(uscalingfactor, currentscale); gl.uniform2fv(urotationvector, currentrotation); gl.uniform4fv(uglobalcolor, [0.1, 0.7, 0.2, 1.0]); this code snippet is taken from the function animatescene() in "a basic 2d webgl animation example." see that...
... after setting the current shading program to shaderprogram, this code fetches the three uniforms "uscalingfactor", "uglobalcolor", and "urotationvector", calling getuniformlocation() once for each uniform.
... finally, the uniform uglobalcolor is set to the color [0.1, 0.7, 0.2, 1.0], the components in this 4-component vector represent the values of red, green, blue, and alpha, respectively.
... having done this, the next time the shading functions are called, their own variables named uscalingfactor, uglobalcolor, and urotationvector will all have the values provided by the javascript code.

Window.window - Web APIs
in web pages, the window object is also a global object.
... this means: global variables of your script are in fact properties of window: var global = {data: 0}; alert(global === window.global); // displays "true" you can access built-in properties of the window object without having to type window.
...alert(window === window.window); // displays "true" the point of having the window property refer to the object itself, was likely to make it easy to refer to the global object.
...for example, if we refer to "this.window.location.href", a javascript module could define a property called "window" inside of a class it defined (since no global "window" variable exists for it by default) which could be created after passing in a window object to the module class' constructor.

<custom-ident> - CSS: Cascading Style Sheets
to prevent ambiguity, each property that uses <custom-ident> forbids the use of specific values: animation-name forbids the global css values (unset, initial, and inherit), as well as none.
... counter-reset counter-increment forbids the global css values (unset, initial, and inherit), as well as none.
... @counter-style list-style-type forbids the global css values (unset, initial, and inherit), as well as the values none, inline, and outside.
... will-change forbids the global css values (unset, initial, and inherit), as well as the values will-change, auto, scroll-position, and contents.

Writing forward-compatible websites - Developer guides
javascript prefix all global variable access in onfoo attributes with “window.” when an event handler content attribute (onclick, onmouseover, and so forth) is used on html element, all name lookup in the attribute first happens on the element itself, then on the element's form if the element is a form control, then on the document, and then on the window (where the global variables you have defined are).
...this happens even if there is a var ownerdocument declared in global scope.
... what this means is that any time you access a global variable in an event handler content attribute, including calling any function declared globally, you can end up with a name collision if a specification adds a new dom property to elements or documents which has the same name as your function or variable, and a browser implements it.
... to avoid this, fully qualify global variable access using "window.", like so: <script> function localname() { alert('function localname has been called'); } </script> <div onclick="window.localname()">clicking me should show an alert<div> don't concatenate scripts you don't control the "use strict;" directive in ecmascript, when used on the file level, applies to everything in the file.

itemid - HTML: Hypertext Markup Language
the itemid global attribute provides microdata in the form of a unique, global identifier of an item.
...also, itemid can only be specified on elements that possess an itemscope attribute whose corresponding itemtype refers to or defines a vocabulary that supports global identifiers.
... the exact meaning of an itemtype's global identifier is provided by the definition of that identifier within the specified vocabulary.
... the vocabulary defines whether several items with the same global identifier can coexist and, if so, how items with the same identifier are handled.

itemtype - HTML: Hypertext Markup Language
the global attribute itemtype specifies the url of the vocabulary that will be used to define itemprop's (item properties) in the data structure.
...they must only be specified on elements with an itemscope attribute, whose itemtype attribute specifies a vocabulary not supporting global identifiers for items, as defined by that vocabulary's specification.
... the exact meaning of a global identifier is determined by the vocabulary's specification.
... it is left to such specifications to define whether multiple items of the same global identifier (whether on the same page or different pages) are allowed to exist, and what processing rules for that vocabulary are, with respect to handling the case of multiple items with the same id.

Numbers and dates - JavaScript
this includes using numbers written in various bases including decimal, binary, and hexadecimal, as well as the use of the global math object to perform a wide variety of mathematical operations on numbers.
... same as the global parsefloat() function.
... same as the global parseint() function.
...more robust version of the original global isnan().

Regular expressions - JavaScript
if escape strings are not already part of your pattern you can add them using string.replace: function escaperegexp(string) { return string.replace(/[.*+\-?^${}()|[\]\\]/g, '\\$&'); // $& means the whole matched string } the "g" after the regular expression is an option or flag that performs a global search, looking in the whole string and returning all matches.
... advanced searching with flags regular expressions have six optional flags that allow for functionality like global and case insensitive searching.
... regular expression flags flag description corresponding property g global search.
... regexp.prototype.global i case-insensitive search.

String.prototype.replace() - JavaScript
to perform a global search and replace, include the g switch in the regular expression.
...(note: the above-mentioned special replacement patterns do not apply in this case.) note that the function will be invoked multiple times for each full match to be replaced if the regular expression in the first parameter is global.
... using global and ignore with replace() global replace can only be done with a regular expression.
... in the following example, the regular expression includes the global and ignore case flags which permits replace() to replace each occurrence of 'apples' in the string with 'oranges'.

WebAssembly - JavaScript
unlike most other global objects, webassembly is not a constructor (it is not a function object).
... webassembly.global() represents a global variable instance, accessible from both javascript and importable/exportable across one or more webassembly.module instances.
...because the instantiatestreaming() function accepts a promise for a response object, you can directly pass it a windoworworkerglobalscope.fetch() call, and it will pass the response into the function when it fulfills.

Transitioning to strict mode - JavaScript
} f(42); this used to change a value on the global object which is rarely the expected effect.
... if you really want to set a value to the global object, pass it as an argument and explicitly assign it as a property: var global = this; // in the top-level context, "this" always // refers to the global object function f(x) { 'use strict'; var a = 12; global.b = a + x * 35; } f(42); trying to delete a non-configurable property 'use strict'; delete object.prototype; // error!
... this in function calls in function calls like f(), the this value was the global object.
...when a function was called with call or apply, if the value was a primitive value, this one was boxed into an object (or the global object for undefined and null).

Understanding WebAssembly text format - WebAssembly
declaring globals in webassembly webassembly has the ability to create global variable instances, accessible from both javascript and importable/exportable across one or more webassembly.module instances.
... in webassembly text format, it looks something like this (see global.wat in our github repo; also see global.html for a live javascript example): (module (global $g (import "js" "global") (mut i32)) (func (export "getglobal") (result i32) (global.get $g)) (func (export "incglobal") (global.set $g (i32.add (global.get $g) (i32.const 1)))) ) this looks similar to what we've seen before, except that we specify a global value using the keyword global, and we also specify the keyword mut along with the value's datatype if we want it to be mutable.
... to create an equivalent value using javascript, you'd use the webassembly.global() constructor: const global = new webassembly.global({value: "i32", mutable: true}, 0); webassembly memory the above example is a pretty terrible logging function: it only prints a single integer!
... in a normal compiled c program, you’d call a function to allocate some memory for the string, but since we’re just writing our own assembly here and we own the entire linear memory, we can just write the string contents into global memory using a data section.

Interacting with page scripts - Archive of obsolete content
page scripts how to send messages between content scripts and page scripts sharing objects with page scripts there are two possible cases here: a content script might want to access an object defined by a page script a content script might want to expose an object to a page script access objects defined by page scripts to access page script objects from content scripts, you can use the global unsafewindow object.
...instead, you need to use the global cloneinto() function to clone the object into the page script's scope.
...from firefox 30 this sharing requires an extra step: the content script needs to explicitly clone the message payload into the page script's scope using the global cloneinto() function: var messenger = document.getelementbyid("message"); messenger.addeventlistener("click", sendcustomevent, false); function sendcustomevent() { var greeting = {"greeting" : "hello world"}; var cloned = cloneinto(greeting, document.defaultview); var event = new customevent("addon-message", { bubbles: true, detail: cloned }); document.documentelement.dispatchevent(event...

Communicating using "port" - Archive of obsolete content
accessing port accessing port in the content script note that the global self object is completely different from the self module, which provides an api for an add-on to access its data files and id.
... in the content script the port object is available as a property of the global self object.
...for example, to receive the context message in a content script associated with a context menu object, you would call the on function attached to the global self object: self.on("context", function() { // handle the message }); so the port property is essentially used here as a namespace for user-defined messages.

...to fix this issue you need to copy the following file from the latest version of firefox to your theme: chrome://global/content/aboutmemory.css.
...source file: chrome://global/skin/media/videocontrols.css the solution to this issue is to add the following name space to the second line of the file right after, and in addition to, the existing @namespace: @namespace html url("http://www.w3.org/1999/xhtml"); you can generate the error console message by going to mozilla's mission page.

Common causes of memory leaks in extensions - Extensions
for example: var windows = []; function injavascriptcodemodule(window) { // forgetting or failing to pop the window again windows.push(window); } both of these cases can happen if you forget to declare local variables with var or let, which means they end up belonging to the global scope.
... for example: function implicitdeclarationleak(window) { // implicit variable declaration in the js global, holding a strong ref to the document doc = window.document; } implicitly declared variables can be avoided by using ecmascript 5's strict mode.
...another solution would be to use the setinterval()/settimeout() instances content windows provide, but there is a big drawback with this idea: if the user disables javascript globally or locally (such as by using an add-on like noscript), then using the content window functions won't work.

Symbol - MDN Web Docs Glossary: Definitions of Web-related terms
global symbol registry there is a global symbol registry holding all available symbols.
... the methods that access the registry are symbol.for() and symbol.keyfor(); these mediate between the global symbol table (or "registry") and the run-time environment.
... the global symbol registry is mostly built by javascript's compiler infrastructure, and the global symbol registry's content is not available to javascript's run-time infrastructure, except through these reflective methods.

Sending form data - Learn web development
an http request consists of two parts: a header that contains a set of global metadata about the browser's capabilities, and a body that can contain information necessary for the server to process the specific request.
... example: raw php php offers some global objects to access the data.
... <?php // the global $_post variable allows you to access the data sent with the post method by name // to access the data sent with the get method, you can use $_get $say = htmlspecialchars($_post['say']); $to = htmlspecialchars($_post['to']); echo $say, ' ', $to; ?> this example displays a page with the data we sent.

Package management basics - Learn web development
as we touched on in the previous article, dependencies can be installed globally or locally to your project.
... although there tend to be more pros for installing globally, the pros for installing locally are more important — such as code portability and version locking.
... in our previous chapter we installed prettier as a global tool.

Chrome Worker Modules
this defines a global value require(), that you may now use as follows: // import the module // (here, we import the core of os.file) let core = require("resource://gre/modules/osfile/osfile_shared_allthreads.jsm"); // we may now use module core.
...to make the value public, you just have to add it to either global value exports, as follows: /* file mymodule.js */ let secretkey = "this is a secret"; let publickey = "this is public"; exports.key = publickey; // secretkey is not exported // publickey is exported with name "key" alternatively, if you prefer that style, you may write // variable |module| is a special global introduced by require() module.exports = { key: publickey }; once this is done, we...
...in particular, globals (string, math, object, self) and the worker global scope itself (this) are shared between workers.

ESLint
here are some common issues: my script is imported into the global browser.xul scope.
... add a line to tell eslint to use the frame-script environment: /* eslint-env mozilla/frame-script */ my script is a worker: add a line to tell eslint to use the worker environment: /* eslint-env worker */ or, to use a chrome worker environment: /* eslint-env mozilla/chrome-worker */ my file uses chrome/xbl specific globals either, specify the global at the top of the file: /* globals mychromeglobal */ or, add to the global section toolkit/.eslintrc.js if it is widely used.
... you'll need to include the following just above it: /* import-globals-from relative/path/to/file.js */ do_check_eq, add_task not defined in a test directory.

Limitations of chrome scripts
however, you must listen to content-document-global-created and document-element-inserted in a frame script.
... to make the shim unnecessary: register event listeners on the global object inside a frame script.
... javascript code modules (jsms) in single-process firefox, you can use javascript code modules (jsms) to maintain global state.

Frame script loading and lifetime
the script just writes "foo" to the command line: // chrome script var mm = gbrowser.selectedbrowser.messagemanager; mm.loadframescript('data:,dump("foo\\n")', true); loadframescript() takes two mandatory parameters: a url that points to the frame script you want to load a boolean flag, allowdelayedload note: if the message manager is a global frame message manager or a window message manager, loadframescript() may load the script multiple times, once in each applicable frame.
... to define the mapping between a chrome:// url and a frame script packaged with an extension, use a "chrome.manifest" file to register a chrome url: // chrome.manifest content my-e10s-extension chrome/content/ // chrome script mm.loadframescript("chrome://my-e10s-extension/content/content.js", true); allowdelayedload if the message manager is a global frame message manager or a window message manager then: if allowdelayedload is true, the frame script will be loaded into any new frame, which has opened after the loadframescript() call.
...{ receivemessage: function() { console.log('incoming message from frame script:', amsg.data); } }, true // must set this argument to true, otherwise sending message from framescript will not work during and after the unload event on the contentmessagemanager triggers ); then in your frame script, listen for the unload event of the message manager (which is the global this), and sending a message.

AddonManager
the addonmanager object is the global api used to access information about add-ons installed in the application and to manipulate them.
... autoupdate_default indicates that the add-on should update automatically only if that's the global default.
... scope_system 8 this add-on is installed somewhere global to the system (installed for all users of the computer).

...} importrelative() imports a javascript code module given the calling javascript code module's global object (you should specify this) and a path relative to that module.
... void importrelative( that, path, scope ); parameters that the javascript object of the calling javascript code module's global scope.

Localization and Plurals
if you're here for pluralrule in the chrome/global/intl.properties file, you'll need to figure out what plural rule to choose for your localization.
...if you don't know how many plural forms you need, check the pluralrule number in chrome/global/intl.properties, and look up the corresponding entry in the following list of plural rules.
... components.utils.import("resource://gre/modules/pluralform.jsm"); methods: get these methods make use of the browser's current locale specified by chrome://global/locale/intl.properties's pluralrule value.

Investigating leaks using DMD heap scan mode
if you are investigating a leak of www.example.com, then from $logdir you can do "grep nsglobalwindow cc-edges* | grep example.com".
... the result of that grep will contain output that looks something like this: cc-edges.15873.log:0x7f0897082c00 [rc=1285] nsglobalwindowinner # 2147483662 inner https://www.example.com/ * cc-edges.15873.log: the first part is the file name where it was found.

L20n Javascript API
alternatively, you can register callbacks to execute when the context is ready (or when globals change and translations need to be updated) with ctx.localize.
... returns an object with the following properties: value: the string value of the entity, attributes: an object of evaluated attributes of the entity, globals: a list of global variables used while evaluating the entity, locale: locale code of the language the entity is in; it can be different than the first locale in the current fallback chain if the entity couldn't be evaluated and a fallback translation had to be used.
... the reason object can be: { locales: array<string> } if callback was invoked because of a change of the current locale (see requestlocales), { global: string } if callback was invoked because the value of one of the globals used in the translation of ids has changed.

nss tech note8
since nss 1.0, up until nss 3.4, there were two global variables that contained the expected session lifetimes for ssl2 and ssl3 sessions.
...if zero, then the called cache function would compute the correct expiration time by adding the chosen timeout (from one of those two global variables) to the sid's creationtime, giving the expirationtime.
... so, in nss 3.4, the global variables ssl3_sid_timeout and ssl_sid_timeout were intended to become the definitions for the client cache only, and each server cache had its own new pair of variables for ssl2 and ssl3 session lifetimes, i.e., cache->ssl2timeout and cache->ssl3timeout.

JS::CloneFunctionObject
if scopechain is omitted, it creates a new function object in cx's global.

... examples this code snippet is from the service worker prefetch sample (see prefetch example live.) the code calls extendableevent.waituntil() in serviceworkerglobalscope.oninstall, delaying treating the serviceworkerregistration.installing worker as installed until the passed promise resolves successfully.

Fetch API - Web APIs
for making a request and fetching a resource, use the windoworworkerglobalscope.fetch() method.
... it is implemented in multiple interfaces, specifically window and workerglobalscope.
... fetch interfaces windoworworkerglobalscope.fetch() the fetch() method used to fetch a resource.

In depth: Microtasks and the JavaScript runtime environment - Web APIs
there are three types of code that create a new execution context: the global context is the execution context created to run the main body of your code; that is, any code that exists outside of a javascript function.
... upon starting the program, the global context is created.
...by using the contexts and the context stack in this manner, many of the fundamentals of how a program operates can be managed, including local and global variables, function calls and returns, and so forth.

Pointer events - Web APIs
interfaces the primary interface is the pointerevent interface which has a constructor plus several event types and associated global event handlers.
... event types and global event handlers pointer events have ten event types, seven of which have similar semantics to their mouse event counterparts (down, up, move, over, out, enter, and leave).
... below is a short description of each event type and its associated global event handler.

Using Service Workers - Web APIs
if successful, the service worker is executed in a serviceworkerglobalscope; this is basically a special kind of worker context, running off the main script execution thread, with no dom access.
...bear in mind therefore that you need to be careful with global variables in the service worker script: each page doesn’t get its own unique worker.
...to do this, we use service worker’s brand new storage api — cache — a global object on the service worker that allows us to store assets delivered by responses, and keyed by their requests.

Window.open() - Web APIs
best practices <script type="text/javascript"> var windowobjectreference = null; // global variable function openffpromotionpopup() { if(windowobjectreference == null || windowobjectreference.closed) /* if the pointer to the window object in memory does not exist or if such pointer exists but the window was closed */ { windowobjectreference = window.open("http://www.spreadfirefox.com/", "promotefirefoxwindowname", "resizable,scrollbars,status"); /* then create i...
... you can also parameterize the function to make it versatile, functional in more situations, therefore re-usable in scripts and webpages: <script type="text/javascript"> var windowobjectreference = null; // global variable function openrequestedpopup(url, windowname) { if(windowobjectreference == null || windowobjectreference.closed) { windowobjectreference = window.open(url, windowname, "resizable,scrollbars,status"); } else { windowobjectreference.focus(); }; } </script> (...) <p><a href="http://www.spreadfirefox.com/" target="promotefirefoxwindow" onclick="openrequestedpop...

init() - Web APIs
[noscript] void init( in nsiprincipal principal, in nsiscriptcontext scriptcontext, in nsiglobalobject globalobject, in nsiuri baseuri, [optional] in nsiloadgroup loadgroup ); parameters principal the principal to use for the request; this must not be null.
... globalobject the object to use as the global for our request.
...if this is specified, it is used even if the global has a window with a load group already established.

Date and time formats used in HTML - HTML: Hypertext Markup Language
global date and time strings a global date and time string specifies a date and time as well as the time zone in which it occurs.

<a>: The Anchor element - HTML: Hypertext Markup Language
attributes this element's attributes include the global attributes.
...allowed values are the same as the global lang attribute.
... note: use the global attribute id instead.

itemscope - HTML: Hypertext Markup Language
itemscope is a boolean global attribute that defines the scope of associated metadata.
...you can use the id attribute to set a global identifier for the new item.
... a global identifier allows the item to relate to other items found on pages across the web.

Closures - JavaScript
they also provide a powerful way of managing your global namespace.
... closure scope chain every closure has three scopes: local scope (own scope) outer functions scope global scope a common mistake is not realizing that, in the case where the outer function is itself a nested function, access to the outer function's scope includes the enclosing scope of the outer function—effectively creating a chain of function scopes.
... // global scope var e = 10; function sum(a){ return function(b){ return function(c){ // outer functions scope return function(d){ // local scope return a + b + c + d + e; } } } } console.log(sum(1)(2)(3)(4)); // log 20 // you can also write without anonymous functions: // global scope var e = 10; function sum(a){ return function sum2(b){ return function sum3(c){ // outer functions scope return function sum4(d){ // local scope return a + b + c + d + e; } } } } var s = sum(1); var s1 = s(2); var s2 = s1(3); var s3 = s2(4); console.log(s3) //log 20 in the example above, there's a series of nested functions, all of which have access to the outer fun...

Memory Management - JavaScript
in this context, the notion of an "object" is extended to something broader than regular javascript objects and also contain function scopes (or the global lexical scope).
...in javascript, the root is the global object.
... cycles are no longer a problem in the first example above, after the function call returns, the two objects are no longer referenced by any resource that is reachable from the global object.

TypeError: "x" is read-only - JavaScript
the javascript strict mode-only exception "is read-only" occurs when a global variable or object property that was assigned to is a read-only property.
... the global variable or object property that was assigned to is a read-only property.
... the global variable undefined is also read-only, so you can't silence the infamous "undefined is not a function" error by doing this: 'use strict'; undefined = function() {}; // typeerror: "undefined" is read-only valid cases 'use strict'; var obj = object.freeze({name: 'score', points: 157}); obj = {name: obj.name, points: 0}; // replacing it with a new object works 'use strict'; var lung_count = 2...

AsyncFunction - JavaScript
note that asyncfunction is not a global object.
... note: async functions created with the asyncfunction constructor do not create closures to their creation contexts; they are always created in the global scope.
... when running them, they will only be able to access their own local variables and global ones, not the ones from the scope in which the asyncfunction constructor was called.

GeneratorFunction - JavaScript
note that generatorfunction is not a global object.
... note: generator function created with the generatorfunction constructor do not create closures to their creation contexts; they are always created in the global scope.
... when running them, they will only be able to access their own local variables and global ones, not the ones from the scope in which the generatorfunction constructor was called.

Infinity - JavaScript
the global property infinity is a numeric value representing infinity.
... description infinity is a property of the global object.
... in other words, it is a variable in global scope.

NaN - JavaScript
the global nan property is a value representing not-a-number.
... description nan is a property of the global object.
... in other words, it is a variable in global scope.

Number.isNaN() - JavaScript
it is a more robust version of the original, global isnan().
... in comparison to the global isnan() function, number.isnan() doesn't suffer the problem of forcefully converting the parameter to a number.
...these would have been true with global isnan() number.isnan('nan'); // false number.isnan(undefined); // false number.isnan({}); // false number.isnan('blabla'); // false // these all return false number.isnan(true); number.isnan(null); number.isnan(37); number.isnan('37'); number.isnan('37.37'); number.isnan(''); number.isnan(' '); specifications specification ecmascript (ecma-262)the defin...

RegExp.prototype.exec() - JavaScript
javascript regexp objects are stateful when they have the global or sticky flags set (e.g.
... true global indicates if the g flag was used for a global match.
... also, be sure that the global flag ("g") is set, or it will also cause an infinite loop.

RegExp.prototype.test() - JavaScript
(this is similar to the string.prototype.match() method.) as with exec() (or in combination with it), test() called multiple times on the same global regular expression instance will advance past the previous match.
...'hello world!'; const result = /^hello/.test(str); console.log(result); // true the following example logs a message which depends on the success of the test: function testinput(re, str) { let midstring; if (re.test(str)) { midstring = 'contains'; } else { midstring = 'does not contain'; } console.log(`${str} ${midstring} ${re.source}`); } using test() on a regex with the "global" flag when a regex has the global flag set, test() will advance the lastindex of the regex.
... the following example demonstrates this behaviour: const regex = /foo/g; // the "global" flag is set // regex.lastindex is at 0 regex.test('foo') // true // regex.lastindex is now at 3 regex.test('foo') // false // regex.lastindex is at 0 regex.test('barfoo') // true // regex.lastindex is at 6 regex.test('foobar') //false // regex.lastindex is at 0 // (...and so on) specifications specification ecmascript (ecma-262)the definition of 'regexp.te...

RegExp - JavaScript
regexp.prototype.global whether to test the regular expression against all possible matches in a string, or only against the first.
... let str = '#foo#' let regex = /foo/y regex.lastindex = 1 regex.test(str) // true regex.lastindex = 5 regex.test(str) // false (lastindex is taken into account with sticky flag) regex.lastindex // 0 (reset after match failure) the difference between the sticky flag and the global flag with the sticky flag y, the next match has to happen at the lastindex position, while with the global flag g, the match can happen at the lastindex position or later: re = /\d/y; while (r = re.exec("123 456")) console.log(r, "and re.lastindex", re.lastindex); // [ '1', index: 0, input: '123 456', groups: undefined ] and re.lastindex 1 // [ '2', index: 1, input: '123 456', groups: undefine...
... with the global flag g, all 6 digits would be matched, not just 3.

String.prototype.match() - JavaScript
return value an array whose contents depend on the presence or absence of the global (g) flag, or null if no matches are found.
... if you want to obtain capture groups and the global flag is set, you need to use regexp.exec() or string.prototype.matchall() instead.
... using global and ignore case flags with match() the following example demonstrates the use of the global and ignore case flags with match().

Symbol.keyFor() - JavaScript
the symbol.keyfor(sym) method retrieves a shared symbol key from the global symbol registry for the given symbol.
... return value a string representing the key for the given symbol if one is found on the global registry; otherwise, undefined.
... examples using keyfor var globalsym = symbol.for('foo'); // create a new global symbol symbol.keyfor(globalsym); // "foo" var localsym = symbol(); symbol.keyfor(localsym); // undefined // well-known symbols are not symbols registered // in the global symbol registry symbol.keyfor(symbol.iterator) // undefined specifications specification ecmascript (ecma-262)the definition of 'symbol.keyfor' in that specification.

TypedArray - JavaScript
there is no global property named typedarray, nor is there a directly visible typedarray constructor.
... instead, there are a number of different global properties, whose values are typed array constructors for specific element types, listed below.
... this constructor is not directly exposed: there is no global %typedarray% or typedarray property.

const - JavaScript
description this declaration creates a constant whose scope can be either global or local to the block in which it is declared.
... global constants do not become properties of the window object, unlike var variables.
... if (my_fav === 7) { // this is fine and creates a block scoped my_fav variable // (works equally well with let to declare a block scoped non const variable) let my_fav = 20; // my_fav is now 20 console.log('my favorite number is ' + my_fav); // this gets hoisted into the global context and throws an error var my_fav = 20; } // my_fav is still 7 console.log('my favorite number is ' + my_fav); const needs to be initialized // throws an error // uncaught syntaxerror: missing initializer in const declaration const foo; const in objects and arrays const also works on objects and arrays.

Leak-hunting strategies and tips
because (1) large graphs of leaked objects tend to include some objects pointed to by global variables that confuse gc-based leak detectors, which can make leaks look smaller (as in bug 99180) or hide them completely and (2) large graphs of leaked objects tend to hide smaller ones, it's much better to go after the large graphs of leaks first.
...seeing a leaked globalwindowimpl, nsxulpdglobalobject, nsxbldocglobalobject, or nsxpcwrappedjs is a sign that there could be significant numbers of js objects leaked.) for example, start with bringing up the mail window and closing the window without doing anything.

Python binding for NSS
the python global interpreter lock (gil) is released prior to calling nss/nspr c functions and reaquired after the nss/nspr c function returns.
...also, any "global" values which are set in python-nss are actually thread-local.

sslintro.html
initialization initialization includes setting up configuration files, setting global defaults, and setting up callback functions.
...sets the global callback function to obtain passwords for pkcs #11 modules.

Rhino Examples
multithreaded script execution dynamicscopes.java is a program that creates a single global scope object and then shares it across multiple threads.
... sharing the global scope allows both information to be shared across threads, and amortizes the cost of context.initstandardobjects by only performing that expensive operation once.

Rhino JavaScript compiler
each global function in the source file is made a method of the generated class, overriding any methods in the base class by the same name.
...each global function in the source file is made a method of the generated class, implementing any methods in the interface by the same name.

Performance Hints
for example, you could rewrite function sum(a) { result = 0; for (i=0; i < a.length; i++) result += a[i]; return result; } as function sum(a) { var result = 0; for (var i=0; i < a.length; i++) result += a[i]; return result; } this is not equivalent code because the second version does not modify global variables result and i.
... however, if you don't intend for any other function to access these variables, then storing them globally is probably wrong anyway (what if you called another function that had a loop like the one in sum!).

Scripting Java
for example: js> javastring.match(/a.*/) ava javaimporter constructor javaimporter is a new global constructor that allows to omit explicit package names when scripting java: var swinggui = javaimporter(packages.javax.swing, packages.javax.swing.event, packages.javax.swing.border, java.awt.event, java.awt.point, java.awt.rectangle, ...
...the class provides additional importpackage() and importclass() global functions for scripts but their extensive usage has tendency to pollute the global name space with names of java classes and prevents loaded classes from garbage collection.

SpiderMonkey compartments

Property cache
↓ o ----> o ----> o ----> o ^global ^x' (----> indicates proto as before; downward arrows ↓ indicate the parent relation) method guarantee — if at time t0 the object x has shape s; and x has an own property p that is a method property (transparently joined function); and at time t1 an object y has shape s; and no shape-regenerating gc occurred; then at time t1 y's own property p is the same method property.
... does the global object always have a unique shape?

JSClass.call
var custom = new specialcustomobject(); custom(); // the jsclass.call hook receives the global object as the obj parameter.
... new custom(); // the jsclass.construct hook receives the global object as the obj parameter.

JSSecurityCallbacks.contentSecurityPolicyAllows
description check whether runtime code generation is allowed for the current global.
... jssecuritycallbacks.contentsecuritypolicyallows is invoked once per global object upon the first attempt to evaluate js code from a string (either through eval or the function constructor).

JS_CloneFunctionObject
this can be helpful if funobj is an extant function that you wish to use as if it were enclosed by a newly-created global object.
...js_clonefunctionobject takes care to choose a prototype that shares a global object with the given parent whenever possible.

JS_ExecuteScript
in the simplest cases, this should just be the embedding's global object.
...scopechain must not include the global object on it; that's implicit.

...when we have js scriptable profiling options available for all tier 1 platforms, we'll look at adding global start/stop profiling functions.

Web Replay
accesses on atomic variables/fields are recorded in a global data stream, as if they were all protected by a global lock.
... similarly, atomic accesses which were included in the recording will occur in the same order during replay, as if they were all protected by a single global lock.

... * * users of the service manager must first obtain a pointer to the * global service manager by calling ns_getservicemanager.

Components.utils.createObjectIn
this function is made available as a global in sandboxes which have the wantexporthelpers option set in the sandbox() constructor.
... to create an object with a specified name, use defineas: var foo = components.utils.createobjectin(mywindow, {defineas: "foo"}); now the target compartment's window has a new global object named foo.
