label: "hello from xpcom", icon: "./icon-16.png", onclick: function() { promptsvc.alert(null, "my add-on", "hello from xpcom"); } }); it's good practice to encapsulate code which uses xpcom by packaging it in its own module.
... getservice(ci.nsipromptservice); exports.alert = function(title, text) { promptsvc.alert(null, title, text); }; if we save this as "alert.js" in our add-on's lib directory, we can rewrite main.js to use it as follows: require("sdk/ui/button/action").actionbutton({ id: "xpcom-example",
label: "hello from xpcom", icon: "./icon-16.png", onclick: function() { require("./alert").alert("my add-on", "hello from xpcom"); } }); one of the benefits of this is that we can control which parts of the add-on are granted chrome privileges, making it easier to review and secure the code.

Creating localizable web applications
so in order to display a localized
label of a category or a tab, you should create a mapping between the non-localizable english names used in the urls and the localizable english strings used in the interface.
...good: $tab_
labels = array( "popular" => _('popular'), "recent" => _('recent'), "all" => _('all'), "my" => _('my'), "favorites" => _('favorites') ); list($category, $tab, $page) = explode('/', $path); if ($tab == 'popular') { // $tab is always english // ....
... echo $tab_
labels($tab); // this will display the translation } indicate the language of the pages you link to indicate the language of the pages you link to if it is different from the user's current language.
...for instance, "log in" as a button
label might be translated by a localizer as the imperative, but for a dialog title, the localizer may choose to use a different form, like gerund (much like "logging in").

XForms Accessibility
name it is formed from value of child xforms
label element if the element doesn't have
labelledby attribute.
...
label specifies the
label for the xforms control (see the spec, the docs).
... every form control other than the output element must contain a
label element.
... the value of
label element is used as name of accessible object.
Accessibility Inspector - Firefox Developer Tools
the name depends on the element; for example, the name of most text elements is simply their textcontent, whereas form elements' names are the contents of their associated <
label>.
...for example, in a form, an entry item could have a "
labelled by" relation with a
label item, which in turn has a "
label for" relation to the entry item.
...the available menu items include: none — don't show the possible list of issues all issues — check for all types of issues contrast — check for issues with visual contrast keyboard — check for issues with navigating via a keyboard text
labels — check for issues with missing text
labels when you one of the menu items, firefox scans your document for the type of issues you selected.
...for a start, you can investigate items that don't have a proper text equivalent — images without alt text and form elements without proper
labels have a name property of null, for example.
Console.table() - Web APIs
the first column in the table will be
labeled (index).
...note that (in firefox) console.table is limited to displaying 1000 rows (first row is the
labeled index).
..., "doe"], ["emily", "jones"]] console.table(people); // an array of objects function person(firstname, lastname) { this.firstname = firstname; this.lastname = lastname; } var john = new person("john", "smith"); var jane = new person("jane", "doe"); var emily = new person("emily", "jones"); console.table([john, jane, emily]); note that if the array contains objects, then the columns are
labeled with the property name.
...objects, logging only firstname function person(firstname, lastname) { this.firstname = firstname; this.lastname = lastname; } var john = new person("john", "smith"); var jane = new person("jane", "doe"); var emily = new person("emily", "jones"); console.table([john, jane, emily], ["firstname"]); sorting columns you can sort the table by a particular column by clicking on that column's
label.

Using the MediaStream Recording API - Web APIs
checkbox hack for showing/hiding this is fairly well documented already, but we thought we'd give a mention to the checkbox hack, which abuses the fact that you can click on the <
label> of a checkbox to toggle it checked/unchecked.
...first of all, we style the <
label> how we want it, making sure that it has enough z-index to always sit above the other elements and therefore be focusable/clickable:
label { font-family: 'notocoloremoji'; font-size: 3rem; position: absolute; top: 2px; right: 3px; z-index: 5; cursor: pointer; } then we hide the actual checkbox, because we don't want it cluttering up our ui: input[type=checkbox] { position: absolute; top: -100px; } next, we style the information screen (wrapped in an <aside> element) how we want it, give it fixed position so that it doesn't appear in the layout flow and affect the main ui, transform it...
...oth showing/hiding: aside { position: fixed; top: 0; left: 0; text-shadow: 1px 1px 1px black; width: 100%; height: 100%; transform: translatex(100%); transition: 0.6s all; background-color: #999; background-image: linear-gradient(to top right, rgba(0,0,0,0), rgba(0,0,0,0.5)); } last, we write a rule to say that when the checkbox is checked (when we click/focus the
label), the adjacent <aside> element will have its horizontal translation value changed and transition smoothly into view: input[type=checkbox]:checked ~ aside { transform: translatex(0); } basic app setup to grab the media stream we want to capture, we use getusermedia().
...we register an event handler for this using mediarecorder.onstop, and finalize our blob there from all the chunks we have received: mediarecorder.onstop = function(e) { console.log("recorder stopped"); const clipname = prompt('enter a name for your sound clip'); const clipcontainer = document.createelement('article'); const clip
label = document.createelement('p'); const audio = document.createelement('audio'); const deletebutton = document.createelement('button'); clipcontainer.classlist.add('clip'); audio.setattribute('controls', ''); deletebutton.innerhtml = "delete"; clip

Movement, orientation, and motion: A WebXR example - Web APIs
function setupxrbutton() { if (navigator.xr.issessionsupported) { navigator.xr.issessionsupported(session_type) .then((supported) => { xrbutton.disabled = !supported; }); } else { navigator.xr.supportssession(session_type) .then(() => { xrbutton.disabled = false; }) .catch(() => { xrbutton.disabled = true; }); } } the
label of the button gets adjusted in the code that handles actuallys ttarting and stopping the webxr session; we'll see that below.
... the webxr session is toggled on and off by the handler for click events on the button, whose
label is appropriately set to either "enter webxr" or "exit webxr".
... viewerstartorientation); xrsession.requestreferencespace(refspacetype) .then((refspace) => { xrreferencespace = refspace.getoffsetreferencespace( new xrrigidtransform(viewerstartposition, cubeorientation)); animationframerequestid = xrsession.requestanimationframe(drawframe); }); return xrsession; } after storing the newly-created xrsession object into xrsession, the
label of the button is set to "exit webxr" to indicate its new function after starting the scene, and a handler is installed for the end event, so we get notified when the xrsession ends.
...in either case, the
label of the button is updated to indicate that a click will start a session, and then, if there is a pending request for an animation frame, we cancel it by calling cancelanimationframe once that's done, the value of xrsession is changed to null to indicate that we're done with the session.

Extra lives - Game development

label that displays the number of lives that remain, and a text
label that will be shown on screen when the player loses one of their lives.
... defining the new text
labels defining the texts look like something we already did in the score lesson.
...to make it easier for us to maintain in the future we can create a separate variable that will hold our styling, let's call it textstyle and place it before the text definitions: textstyle = { font: '18px arial', fill: '#0095dd' }; we can now use this variable when stlying our text
labels — update your code so that the multiple instances of the text styling are replaced with the variable: scoretext = game.add.text(5, 5, 'points: 0', textstyle); livestext = game.add.text(game.world.width-5, 5, 'lives: '+lives, textstyle); livestext.anchor.set(1,0); lifelosttext = game.add.text(game.world.width*0.5, game.world.height*0.5, 'life lost, click to continue', textstyle); lifelosttext.
Assessment: Accessibility troubleshooting - Learn web development
the forms the <input> element in the search form at the top could do with a
label, but we don't want to add a visible text
label that would potentially spoil the design and isn't really needed by sighted users.
... how can you add a
label that is only accessible to screenreaders?
... the two <input> elements in the comment form have visible text
labels, but they are not unambiguously associated with their
labels — how do you achieve this?
Accessible multimedia - Learn web development
we will first need to store references to each of the controls — add the following to the top of your javascript file: const playpausebtn = document.queryselector('.playpause'); const stopbtn = document.queryselector('.stop'); const rwdbtn = document.queryselector('.rwd'); const fwdbtn = document.queryselector('.fwd'); const time
label = document.queryselector('.time'); next, we need to grab a reference to the video/audio player itself — add this line below the previous lines: const player = document.queryselector('video'); this holds a reference to a htmlmediaelement object, which has several useful properties and methods available on it that can be used to wire up functionality to our buttons.
... let minutes = math.floor(player.currenttime / 60); let seconds = math.floor(player.currenttime - minutes * 60); let minutevalue; let secondvalue; if (minutes<10) { minutevalue = "0" + minutes; } else { minutevalue = minutes; } if (seconds<10) { secondvalue = "0" + seconds; } else { secondvalue = seconds; } mediatime = minutevalue + ":" + secondvalue; time
label.textcontent = mediatime; }; each time the time updates (once per second), we fire this function.
... it works out the number of minutes and seconds from the given currenttime value (which is in seconds), adds a leading 0 if either the minute or second value is less than 10, and then creates the display readout and adds it to the time
label.
The HTML5 input types - Learn web development

...you could display an input value or the output of a calculation inside any element, but <output> is special — like <

Using the alertdialog role - Accessibility
this means that most of the instructions provided in the 'using the dialog role' technique are applicable to the alertdialog role as well: the alert dialog must always be given an accessible name (through aria-

Control flow and error handling - JavaScript
' + `${document.form1.threechar.value} is not valid.`); return false; } } switch statement a switch statement allows a program to evaluate an expression and attempt to match the expression's value to a case
label.
... a switch statement looks like this: switch (expression) { case
label_1: statements_1 [break;] case
label_2: statements_2 [break;] … default: statements_def [break;] } javascript evaluates the above switch statement as follows: the program first looks for a case clause with a
label matching the value of expression and then transfers control to that clause, executing the associated statements.
... if no matching
label is found, the program looks for the optional default clause: if a default clause is found, the program transfers control to that clause, executing the associated statements.
block - JavaScript
the block is delimited by a pair of braces ("curly brackets") and may optionally be
labelled: the source for this interactive example is stored in a github repository.
... syntax block statement { statementlist }
labelled block statement
labelidentifier: { statementlist } statementlist statements grouped within the block statement.
...
labelidentifier an optional
label for visual identification or as a target for break.
Statements and declarations - JavaScript
break terminates the current loop, switch, or
label statement and transfers program control to the statement following the terminated statement.
... continue terminates execution of the statements in the current iteration of the current or
labeled loop, and continues execution of the loop with the next iteration.
...
label provides a statement with an identifier that you can refer to using a break or continue statement.

Sending forms through JavaScript - Learn web development
the html is typical: <form id="myform"> <
label for="myname">send me your name:</
label> <input id="myname" name="name" value="john"> <input type="submit" value="send me!"> </form> but javascript takes over the form: window.addeventlistener( "load", function () { function senddata() { const xhr = new xmlhttprequest(); // bind the formdata object and the form element const fd = new formdata( form ); // define what happe...
... in the following example, we use the filereader api to access binary data and then build the multi-part form data request by hand: <form id="theform"> <p> <
label for="thetext">text data:</
label> <input id="thetext" name="mytext" value="some text data" type="text"> </p> <p> <
label for="thefile">file data:</
label> <input id="thefile" name="myfile" type="file"> </p> <button>send me!</button> </form> as you see, the html is a standard <form>.
Creating hyperlinks - Learn web development
keep your link
label as short as possible — this is helpful because screen readers need to interpret the entire link text.
...this can cause problems for screen reader users, if there's a list of links out of context that are
labeled "click here", "click here", "click here".

Basic math in JavaScript — numbers and operators - Learn web development
for example, booleans can be used to: display the correct text
label on a button depending on whether a feature is turned on or off display a game over message if a game is over or a victory message if the game has been won display the correct seasonal greeting depending what holiday season it is zoom a map in or out depending on what zoom level is selected we'll look at how to code such logic when we look at conditional statements in a future article.
...if the button is currently saying "start machine" when it is pressed, we change its
label to "stop machine", and update the
label as appropriate.
Ember interactivity: Events, classes and state - Learn web development
add the new line shown below to your header.hbs file: <input class='new-todo' aria-
label='what needs to be done?' placeholder='what needs to be done?' autofocus {{on 'keydown' this.onkeydown}} > this new attribute is inside double curly braces, which tells you it is part of ember's dynamic templating syntax.
... this is because the text
label inside each list item is hardcoded to that text, as seen in todo.hbs: <
label>buy movie tickets</
label> update this line to use the argument @todo — which will represent the todo that we passed in to this component when it was invoked in todo-list.hbs, in the line <todo @todo={{todo}} />: <
label>{{@todo.text}}</
label> ok, try it again.
React interactivity: Events and state - Learn web development
your form.js file should now read like this: import react, { usestate } from "react"; function form(props) { const [name, setname] = usestate(""); function handlechange(e) { setname(e.target.value); } function handlesubmit(e) { e.preventdefault(); props.addtask(name); setname(""); } return ( <form onsubmit={handlesubmit}> <h2 classname="
label-wrapper"> <
label htmlfor="new-todo-input" classname="
label__lg"> what needs to be done?
... </
label> </h2> <input type="text" id="new-todo-input" classname="input input__lg" name="text" autocomplete="off" value={name} onchange={handlechange} /> <button type="submit" classname="btn btn__primary btn__lg"> add </button> </form> ); } export default form; putting it all together: adding a task now that we've practiced with events, callback props, and hooks we're ready to write functionality that will allow a user to add a new task from their browser.
Getting started with Svelte - Learn web development
label, and choosing inspect: when compiling the app, svelte changes our h1 styles definition to h1.svelte-1tky8bj, and then modifies every <h1> element in our component to <h1 class="svelte-1tky8bj">, so that it picks up the styles as required.
... as you can see, the <h1>
label is automatically updated.
Handling common HTML and CSS problems - Learn web development

label,...
... input { margin-bottom: 20px; } div { clear: both; margin: 10px; } body { width: 400px; margin: 0 auto; } <form> <div> <

gettext
for instance, "log in" as a button
label might be translated by a localizer as the imperative, but for a dialog title, the localizer may choose to use a different form, like gerund (much like "logging in").
...in the po file, msgctxt looks like this: msgctxt "button
label" msgid "log in" msgstr "" msgctxt "dialog title" msgid "log in" msgstr "" you can add context to your strings by passing an additional argument to the gettext function call and then having xgettext extract it as the context.

Index - Firefox Developer Tools
after firefox 48, the default view is the tree map view, and you can switch to the aggregate view using the dropdown
labeled "view:": 39 basic operations before firefox 50, the memory tool is not enabled by default.
...then record a profile as usual, and you will see a new tab
labeled "allocations" in the toolbar: 84 call tree javascript, performance, memory the call tree is a sampling profiler.
Aggregate view - Firefox Developer Tools
after firefox 48, the default view is the tree map view, and you can switch to the aggregate view using the dropdown
labeled "view:": the aggregate view looks something like this: it presents a breakdown of the heap's contents, as a table.
... there are three main ways to group the data: type call stack inverted call stack you can switch between them using the dropdown menu
labeled "group by:" located at the top of the panel: there's also a box
labeled "filter" at the top-right of the pane.
Basic operations - Firefox Developer Tools
to load a snapshot from an existing .fxsnapshot file, click the import button, which looks like a rectangle with an arrow rising from it (before firefox 49, this button was
labeled with the text "import..."): you'll be prompted to find a snapshot file on disk.
...to do this, check "record call stacks" (before firefox 49 this was
labeled "record allocation stacks"): ...
Allocations - Firefox Developer Tools
then record a profile as usual, and you will see a new tab
labeled "allocations" in the toolbar: anatomy of the allocations view the allocations view looks something like this: the allocations view periodically samples allocations that are made over the recording.
... if a gc event was caused by allocation pressure, then the sidebar on the right of the marker in the waterfall view contains a link
labeled "show allocation triggers".

labeled "use requestanimationframe" and capture another profile.
Taking screenshots - Firefox Developer Tools
to enable it: visit the settings page find the section
labeled "available toolbox buttons" check the box
labeled "take a screenshot of the entire page".
...just check the box in settings
labeled "screenshot to clipboard": now, whenever you take a screenshot, the screenshot is also copied to the clipboard.
View Source - Firefox Developer Tools
for example view-source:https://www.mozilla.org/#line100 view selection source if you select part of a web page and conext-click, you'll see a context menu item
labeled "view selection source", that behaves just like "view page source", except you only see the source for the selection.
... view mathml source if you context-click while the mouse is over some mathml, you'll see a context menu item
labeled "view mathml source": click it to see the mathml source.
Web Audio Editor - Firefox Developer Tools
now there should be an extra tab in the toolbox toolbar
labeled "web audio".
...if, instead, you've connected a node to an audioparam in another node, then the connection is shown as a dashed line between the nodes, and is
labeled with the name of the audioparam: inspecting and modifying audionodes if you click on a node, it's highlighted and you get a node inspector on the right hand side.

How to turn off form autocompletion - Web security
disabling autocompletion to disable autocompletion in forms, you can set the autocomplete attribute to "off": autocomplete="off" you can do this either for an entire form, or for specific input elements in a form: <form method="post" action="/form" autocomplete="off"> […] </form> <form method="post" action="/form"> […] <div> <
label for="cc">credit card:</
label> <input type="text" id="cc" name="cc" autocomplete="off"> </div> </form> setting autocomplete="off" on fields has two effects: it tells the browser not to save data inputted by the user for later autocompletion on similar forms, though heuristics for complying vary by browser.
