context-menu - Archive of obsolete content
declarative contexts you can specify some simple, declarative contexts when you create a menu item by setting the context property of the options object passed to its constructor, like this: var cm = require("sdk/context-menu"); cm.item({ label: "my menu item", context: cm.urlcontext("*.mozilla.org") }); constructor description pagecontext() the page context.
...the example above works because <img> elements can't contain other elements, but in the example below, node.nodename is not guaranteed to be "p" - for example, it won't be "p" if the user context-clicked a link inside a paragraph: var cm = require("sdk/context-menu"); cm.item({ label: "a paragraph", context: cm.selectorcontext("p"), contentscript: 'self.on("context", function (node) {' + ' console.log(node.nodename);' + ' return true;' + '});' }); the content script is executed for every page that a context menu is shown for.
... for example, suppose your add-on looks like this: var script = "self.on('click', function (node, data) {" + " console.log('clicked: ' + node.nodename);" + "});"; var cm = require("sdk/context-menu"); cm.item({ label: "body context", context: cm.selectorcontext("body"), contentscript: script }); this add-on creates a context-menu item that uses selectorcontext to display the item whenever the context menu is activated on any descendant of the <body> element.

Handling common JavaScript problems - Learn web development
storically, javascript was plagued with cross-browser compatibility problems — back in the 1990s, the main browser choices back then (internet explorer and netscape) had scripting implemented in different language flavours (netscape had javascript, ie had jscript and also offered vbscript as an option), and while at least javascript and jscript were compatible to some degree (both based on the ecmascript specification), things were often implemented in conflicting, incompatible ways, causing developers many nightmares.
... when developers make use of new/nascent javascript features (for example ecmascript 6 / ecmascript next features, modern web apis...) in their code, and find that such features don't work in older browsers.
...the javascript/ecmascript linters we'd recommend are jshint and eslint; these can be used in a variety of ways, some of which we'll detail below.

Function - MDN Web Docs Glossary: Definitions of Web-related terms
only function expressions can be anonymous, function declarations must have a name: // when used as a function expression (function () {}); // or using the ecmascript 2015 arrow notation () => {}; the following terms are not used in the ecmascript language specification, they're jargon used to refer to different types of functions.
... a named function is a function with a function name: // function declaration function foo() {}; // named function expression (function bar() {}); // or using the ecmascript 2015 arrow notation const foo = () => {}; an inner function is a function inside another function (square in this case).
... an outer function is a function containing a function (addsquares in this case): function addsquares(a,b) { function square(x) { return x * x; } return square(a) + square(b); }; //using ecmascript 2015 arrow notation const addsquares = (a,b) => { const square = x => x*x; return square(a) + square(b); }; a recursive function is a function that calls itself.
... function loop(x) { if (x >= 10) return; loop(x + 1); }; //using ecmascript 2015 arrow notation const loop = x => { if (x >= 10) return; loop(x + 1); }; an immediately invoked function expressions (iife) is a function that is called directly after the function is loaded into the browser’s compiler.

Command line crash course - Learn web development
the next images show the command prompts available in windows — there’s a good range of options from the "cmd" program to "powershell" — which can be run from the start menu by typing the program name.
... windows has traditionally had its own terminal-like program called cmd (“the command prompt”) for a long time, but this definitely doesn’t have parity with unix commands, and is equivalent to the old-style windows dos prompt.
...you could stick with the default command prompt (cmd), and many tools will work ok, but you’ll find everything easier if you have better parity with unix tools.
...note that this won’t work if you’re using the default windows command prompt (cmd) — the equivalent there is dir.

git can be downloaded and installed via the git-scm website — download the relevant installer for your system, run it, and follow the on-screen prompts.
... to configure prettier, give .prettierrc.json the following contents: { "singlequote": true, "trailingcomma": "es5" } with these settings, when prettier formats javascript for you it will use single quotes for all your quoted values, and it won't use trailing commas (a newer feature of ecmascript that will cause errors in older browsers).
... next up, we’ll configure eslint — create another file in the root of your will-it-miss directory called .eslintrc.json, and give it the following contents: { "env": { "es6": true, "browser": true }, "extends": "eslint:recommended", "parseroptions": { "ecmaversion": 6, "sourcetype": "module" }, "rules": { "no-console": 0 } } the above eslint configuration says that we want to use the "recommended" eslint settings, that we're going to allow usage of es6 features (such as map() or set()), that we can use module import statements, and that using console.log() is allowed.
... the final config file should look like this — add in the bolded parts and save it: { "env": { "es6": true, "browser": true }, "extends": ["eslint:recommended", "plugin:react/recommended"], "parseroptions": { "ecmaversion": 6, "sourcetype": "module", "ecmafeatures": { "jsx": true } }, "plugins": ["react"], "rules": { "semi": "error", "no-console": 0, "react/jsx-uses-vars": "error" } } as the configuration now uses a plugin called "react", this development dependency also needs to be installed, so that the code is there to actually run that part of the linting proces...

Cross Process Object Wrappers
passing cpows from frame scripts frame scripts can send messages to chrome using one of two global functions: sendasyncmessage() or sendsyncmessage().
...for example, this frame script sends a dom node to chrome when the user clicks it, as the clicked property of the third argument: // frame script addeventlistener("click", function (event) { sendasyncmessage("my-e10s-extension-message", {}, { clicked : event.target }); }, false); in the chrome script, the dom node is now accessible through a cross process object wrapper, as a property of the objects property of the message.
...*/ var button = content.document.getelementbyid("click-me"); button.addeventlistener("mouseover", function (event) { sendasyncmessage("my-addon-message", {}, { element : event.target }); }, false); // chrome script /* load the frame script, then listen for the message.
...consider this code: mm.addmessagelistener("gotloadevent", function (msg) { mm.sendasyncmessage("changedocumenturi", {newuri: "hello.com"}); let uri = msg.objects.document.documenturi; dump("received load event: " + uri + "\n"); }); this sends a message asking the frame script to change the current document uri, then accesses the current document uri via a cpow.

An overview of NSS Internals
the file could be named secmod.db, but in newer database generations a file named pkcs11.txt is used.
...nss has an ssl/tls module that implements the secure sockets layer/transport layer security network protocols, an s/mime module that implements cms messaging used by secure email and some instant messaging implementations, a dbm library that implements the classic database storage, and finally a core nss library for the big set of “everything else”.
... when dealing with certificates (x.509), file formats such as pkcs#12 (certificates and keys), pkcs#7 (signed data), and message formats as cms, we should mention asn.1, which is a syntax for storing structured data in a very efficient (small sized) presentation.
...there are tools for managing nss databases, for dumping or verifying certificates, for registering pkcs#11 modules with a database, for processing cms encrypted/signed messages, etc.

Inheritance in JavaScript - Learn web development
in addition, we present some advice on when and where you might use oojs, and look at how classes are dealt with in modern ecmascript syntax.
... you might also be interested in checking out some of the new ecmascript features that allow us to do inheritance more cleanly in javascript (see classes).
... ecmascript 2015 classes ecmascript 2015 introduces class syntax to javascript as a way to write reusable classes using easier, cleaner syntax, which is more similar to classes in c++ or java.

Object prototypes - Learn web development
in the next article, we talk about the modern way of doing things, which provides easier syntax to achieve the same things — see ecmascript 2015 classes.
... note: before ecmascript 2015, there wasn't officially a way to access an object's prototype directly — the "links" between the items in the chain are defined in an internal property, referred to as [[prototype]] in the specification for the javascript language (see ecmascript).
... since ecmascript 2015, you can access an object's prototype object indirectly via object.getprototypeof(obj).

Introduction to client-side frameworks - Learn web development
s to client-side frameworks if you’re looking for tools to expedite the web development process, and you know your project isn’t going to require intensive client-side javascript, you could reach for one of a handful of other solutions for building the web: a content management system server-side rendering a static site generator content management systems content-management systems (cmses) are any tools that allow a user to create content for the web without directly writing code themselves.
...they do, however, require a significant amount of time to set up, and utilizing a cms means that you surrender at least some measure of control over the final output of your website.
... for example: if your chosen cms doesn't author accessible content by default, it's often difficult to improve this.

Handling common accessibility problems - Learn web development
you might have inherited a site where the semantics are not very good (perhaps you've ended up with a horrible cms that generates buttons made with <div>s), or you are using a complex control that does not have keyboard accessibility built in, like the html5 <video> element (amazingly, opera is the only browser that allows you to tab through the <video> element's default browser controls).

Self-hosted builtins in SpiderMonkey
self-hosted functions by default are not constructors and do not have a prototype property, so that they meet the requirements for standard built-in functions as described in the ecmascript language specification 5.1, clause 15.
...some general-purpose functions provided in this way are: the abstract operations toobject, tointeger, and iscallable specified in the ecmascript language specification.
...of note, it provides implementations of list and record, types defined in the ecmascript specifications that are similar to array and object, but can't be modified by application code.

JSClass.flags
(ecmascript specifies a single global object, but in spidermonkey the global object is the last object in the scope chain, which can be different objects at different times.
...js_setglobalobject sets an object which is sometimes used as the global object, as a last resort.) enable standard ecmascript behavior for setting the prototype of certain objects, such as function objects.
... if the global object does not have this flag, then scripts may cause nonstandard behavior by replacing standard constructors or prototypes (such as function.prototype.) objects that can end up with the wrong prototype object, if this flag is not present, include: arguments objects (ecma 262-3 §10.1.8 specifies "the original object prototype"), function objects (ecma 262-3 §13.2 specifies "the original function prototype"), and objects created by many standard constructors (ecma 262-3 §15.4.2.1 and others).

JS_DefaultValue
ecmascript specifies that all objects have a [[defaultvalue]] hook.
... objects with classes defined by ecmascript itself all use the [[defaultvalue]] algorithm specified in §8.12.8 (but note the algorithm's special case for date objects).
...behavior when the convert hook is js_convertstub is identical to that for objects defined by ecmascript.

JS_SealObject
as of spidermonkey 1.8.5, js_sealobject has been removed from the jsapi, because ecmascript 5 includes a "seal" concept (namely, that of object.seal) which is quite different from that of js_sealobject.
... moreover, js_sealobject's exact semantics are subtly incompatible with ecmascript.
... js_freezeobject and js_deepfreezeobject are near-substitutes compatible with ecmascript semantics, implementing semantics compatible with those of object.freeze.

JS_ValueToNumber

Control flow and error handling - JavaScript
important: javascript before ecmascript2015 (6th edition) does not have block scope!
...(in c or java, the equivalent code would have outputted 1.) since ecmascript2015, the let and const variable declarations are block-scoped.
...while it is common to throw numbers or strings as errors, it is frequently more effective to use one of the exception types specifically created for this purpose: ecmascript exceptions domexception and domerror throw statement use the throw statement to throw an exception.

Numbers and dates - JavaScript
var n = 0755; // 493 var m = 0644; // 420 strict mode in ecmascript 5 forbids octal syntax.
... octal syntax isn't part of ecmascript 5, but it's supported in all browsers by prefixing the octal number with a zero: 0644 === 420 and "\045" === "%".
... in ecmascript 2015, octal numbers are supported if they are prefixed with 0o, e.g.: var a = 0o10; // es2015: 8 hexadecimal numbers hexadecimal number syntax uses a leading zero followed by a lowercase or uppercase latin letter "x" (0x or 0x).

Classes - JavaScript
strict mode the body of a class is executed in strict mode, i.e., code written here is subject to stricter syntax for increased performance, some otherwise silent errors will be thrown, and certain keywords are reserved for future versions of ecmascript.
...an ecmascript class can only have a single superclass, so multiple inheritance from tooling classes, for example, is not possible.
... a function with a superclass as input and a subclass extending that superclass as output can be used to implement mix-ins in ecmascript: let calculatormixin = base => class extends base { calc() { } }; let randomizermixin = base => class extends base { randomize() { } }; a class that uses these mix-ins can then be written like this: class foo { } class bar extends calculatormixin(randomizermixin(foo)) { } specifications specification ecmascript (ecma-262)the definition of 'class definitions' in that specification.

arguments.callee - JavaScript
warning: the 5th edition of ecmascript (es5) forbids use of arguments.callee() in strict mode.
...l due to checks that would not otherwise be necessary.) the other major issue is that the recursive call will get a different this value, e.g.: var global = this; var sillyfunction = function(recursed) { if (!recursed) { return arguments.callee(true); } if (this !== global) { alert('this is: ' + this); } else { alert('this is the global'); } } sillyfunction(); ecmascript 3 resolved these issues by allowing named function expressions.
... however, in a case like the following, there are not alternatives to arguments.callee, so its deprecation could be a bug (see bug 725398): function createperson(sidentity) { var operson = new function('alert(arguments.callee.identity);'); operson.identity = sidentity; return operson; } var john = createperson('john smith'); john(); specifications specification ecmascript (ecma-262)the definition of 'arguments exotic objects' in that specification.

Building up a basic demo with Three.js - Game development
let's play with the last two later, but for now, the basic one should be enough: var basicmaterial = new three.meshbasicmaterial({color: 0x0095dd}); add this line below the previously added.
...this takes on a shape, and adds the specified material to every face: var cube = new three.mesh(boxgeometry, basicmaterial); again, add this line below the one you previously added.

GLSL Shaders - Game development
applying the shaders to actually apply the newly created shaders to the cube, comment out the basicmaterial definition first: // var basicmaterial = new three.meshbasicmaterial({color: 0x0095dd}); then, create the shadermaterial: var shadermaterial = new three.shadermaterial( { vertexshader: document.getelementbyid( 'vertexshader' ).textcontent, fragmentshader: document.getelementbyid( 'fragmentshader' ).textcontent }); this shader material takes the code from the scripts and applies it ...
... then, in the line that defines the cube we need to replace the basicmaterial: var cube = new three.mesh(boxgeometry, basicmaterial); ...with the newly created shadermaterial: var cube = new three.mesh(boxgeometry, shadermaterial); three.js compiles and runs the shaders attached to the mesh to which this material is given.

SpiderMonkey Internals
in addition to the interpreter, spidermonkey contains a just-in-time (jit) compiler, a garbage collector, code implementing the basic behavior of javascript values, a standard library implementing ecma 262-5.1 §15 with various extensions, and a few public apis.
...(otherwise, spidermonkey converts primitive values to objects before invoking their methods, per ecma 262-3 §11.2.1.) error handling spidermonkey has two interdependent error-handling systems: javascript exceptions (which are not implemented with, or even compatible with, any kind of native c/c++ exception handling) and error reporting.

JSAPI User Guide
for maximum ecmascript standard compliance, applications should also use js_setoptions to enable jsoption_varobjfix.

JSObjectOps.defaultValue
description the jsobjectops.defaultvalue callback corresponds to the [[defaultvalue]] method defined in ecma 262-3 §8.6.2.6.
... many expressions in the ecmascript language, such as a+b, involve implicit conversion of the operands using [[defaultvalue]].

JSPropertyOp
this is typically the value of the left-hand side after assignment, as opposed to the value of the right-hand side, as required by ecma 262-3 §11.13.
... this ecmascript incompatibility is observable when assigning to the length property of an array, for example.

eval() - JavaScript
var expression = new string('2 + 2'); eval(expression.tostring()); // returns 4 if you use the eval function indirectly, by invoking it via a reference other than eval, as of ecmascript 5 it works in the global scope rather than the local scope.
...turns 2 console.log('b is : ' + b); a = false; b = eval(str); // returns 3 console.log('b is : ' + b); eval as a string defining function requires "(" and ")" as prefix and suffix var fctstr1 = 'function a() {}' var fctstr2 = '(function a() {})' var fct1 = eval(fctstr1) // return undefined var fct2 = eval(fctstr2) // return a function specifications specification ecmascript (ecma-262)the definition of 'eval' in that specification.

Iteration protocols - JavaScript
as a couple of additions to ecmascript 2015, iteration protocols aren't new built-ins or syntax, but protocols.
...onsole.log(ageneratorobject[symbol.iterator]() === ageneratorobject); // true, because its @@iterator method returns itself (an iterator), so it's an well-formed iterable console.log([...ageneratorobject]); // [1, 2, 3] console.log(symbol.iterator in ageneratorobject) // true, because @@iterator method is a property of ageneratorobject specifications specification ecmascript (ecma-262)the definition of 'iteration' in that specification.

Destructuring assignment - JavaScript
let key = 'z'; let {[key]: foo} = {z: 'bar'}; console.log(foo); // "bar" rest in object destructuring the rest/spread properties for ecmascript proposal (stage 4) adds the rest syntax to destructuring.

Property accessors - JavaScript
(in the ecmascript standard, the names of properties are technically "identifiernames", not "identifiers", so reserved words can be used but are not recommended).
...it is better to use bracket notation instead: x = document.forms['form_name'].elements[strformcontrol].value specifications specification ecmascript (ecma-262)the definition of 'property accessors' in that specification.

class expression - JavaScript
the class expression is one way to define a class in ecmascript 2015.

delete operator - JavaScript
console.log(delete func); // false cross-browser notes although ecmascript makes iteration order of objects implementation-dependent, it may appear that all major browsers support an iteration order based on the earliest added property coming first (at least for properties not on the prototype).
...in the following example, trees[3] is removed from the array completely using splice(): var trees = ['redwood', 'bay', 'cedar', 'oak', 'maple']; trees.splice(3,1); console.log(trees); // ["redwood", "bay", "cedar", "maple"] specifications specification ecmascript (ecma-262)the definition of 'the delete operator' in that specification.

this - JavaScript
function bar() { console.log(object.prototype.tostring.call(this)); } bar.call(7); // [object number] bar.call('foo'); // [object string] bar.call(undefined); // [object global] the bind method ecmascript 5 introduced function.prototype.bind().

label - JavaScript
foo: { console.log('face'); break foo; console.log('this will not be executed'); } console.log('swap'); // this will log: // "face" // "swap" labeled function declarations starting with ecmascript 2015, labeled function declarations are now standardized for non-strict code in the web compatibility annex of the specification.
... l: function f() {} in strict mode code, however, this will throw a syntaxerror: 'use strict'; l: function f() {} // syntaxerror: functions cannot be labelled generator functions can neither be labeled in strict code, nor in non-strict code: l: function* f() {} // syntaxerror: generator functions cannot be labelled specifications specification ecmascript (ecma-262)the definition of 'labelled statement' in that specification.

switch - JavaScript
block-scope variables within switch statements with ecmascript 2015 (es6) support made available in most modern browsers, there will be cases where you would want to use let and const statements to declare block-scoped variables.
... specifications specification ecmascript (ecma-262)the definition of 'switch statement' in that specification.

Transitioning to strict mode - JavaScript
ecmascript 5 introduced strict mode which is now implemented in all major browsers (including ie10).
... differences from non-strict to strict syntax errors when adding 'use strict';, the following cases will throw a syntaxerror before the script is executing: octal syntax var n = 023; with statement using delete on a variable name delete myvariable; using eval or arguments as variable or function argument name using one of the newly reserved keywords (in prevision for ecmascript 2015): implements, interface, let, package, private, protected, public, static, and yield declaring function in blocks if (a < b) { function f() {} } obvious errors declaring twice the same name for a property name in an object literal {a: 1, b: 3, a: 7} this is no longer the case in ecmascript 2015 (bug 1041128).

Test your skills: CSS and JavaScript accessibility - Learn web development
we'd like you to assume that the existing ruleset with the a selector is supplied by some cms, and that you can't change it — instead, you need to create new rules to make the links look and behave like links, and for the user to be able to tell where they are in the list.

Cascade and inheritance - Learn web development
one situation in which you may have to use it is when you are working on a cms where you can't edit the core css modules, and you really want to override a style that can't be overridden in any other way.

Debugging CSS - Learn web development

Combinators - Learn web development
that said, your knowledge of combinators will come in very useful if you need to get to something in your document and are unable to access the html, perhaps due to it being generated by a cms.

Pseudo-classes and pseudo-elements - Learn web development
instead of adding the class, we could use the :first-child pseudo-class selector — this will always target the first child element in the article, and we will no longer need to edit the html (this may not always be possible anyway, maybe due to it being generated by a cms.) all pseudo-classes behave in this same kind of way.
