250 * Binds a handler to a particular event (like click) for each matched element.
251 * The event handler is passed an event object that you can use to prevent
252 * default behaviour. To stop both default action and event bubbling, your handler
253 * has to return false.
255 * In most cases, you can define your event handlers as anonymous functions
256 * (see first example). In cases where that is not possible, you can pass additional
257 * data as the second parameter (and the handler function as the third), see
260 * Calling bind with an event type of "unload" will automatically
261 * use the one method instead of bind to prevent memory leaks.
263 * @example $("p").bind("click", function(){
264 * alert( $(this).text() );
266 * @before <p>Hello</p>
267 * @result alert("Hello")
269 * @example function handler(event) {
270 * alert(event.data.foo);
272 * $("p").bind("click", {foo: "bar"}, handler)
273 * @result alert("bar")
274 * @desc Pass some additional data to the event handler.
276 * @example $("form").bind("submit", function() { return false; })
277 * @desc Cancel a default action and prevent it from bubbling by returning false
278 * from your function.
280 * @example $("form").bind("submit", function(event){
281 * event.preventDefault();
283 * @desc Cancel only the default action by using the preventDefault method.
286 * @example $("form").bind("submit", function(event){
287 * event.stopPropagation();
289 * @desc Stop only an event from bubbling by using the stopPropagation method.
293 * @param String type An event type
294 * @param Object data (optional) Additional data passed to the event handler as event.data
295 * @param Function fn A function to bind to the event on each of the set of matched elements
298 bind: function( type, data, fn ) {
299 return type == "unload" ? this.one(type, data, fn) : this.each(function(){
300 jQuery.event.add( this, type, fn || data, fn && data );
305 * Binds a handler to a particular event (like click) for each matched element.
306 * The handler is executed only once for each element. Otherwise, the same rules
307 * as described in bind() apply.
308 * The event handler is passed an event object that you can use to prevent
309 * default behaviour. To stop both default action and event bubbling, your handler
310 * has to return false.
312 * In most cases, you can define your event handlers as anonymous functions
313 * (see first example). In cases where that is not possible, you can pass additional
314 * data as the second paramter (and the handler function as the third), see
317 * @example $("p").one("click", function(){
318 * alert( $(this).text() );
320 * @before <p>Hello</p>
321 * @result alert("Hello")
325 * @param String type An event type
326 * @param Object data (optional) Additional data passed to the event handler as event.data
327 * @param Function fn A function to bind to the event on each of the set of matched elements
330 one: function( type, data, fn ) {
331 return this.each(function(){
332 jQuery.event.add( this, type, function(event) {
333 jQuery(this).unbind(event);
334 return (fn || data).apply( this, arguments);
340 * The opposite of bind, removes a bound event from each of the matched
343 * Without any arguments, all bound events are removed.
345 * If the type is provided, all bound events of that type are removed.
347 * If the function that was passed to bind is provided as the second argument,
348 * only that specific event handler is removed.
350 * @example $("p").unbind()
351 * @before <p onclick="alert('Hello');">Hello</p>
352 * @result [ <p>Hello</p> ]
354 * @example $("p").unbind( "click" )
355 * @before <p onclick="alert('Hello');">Hello</p>
356 * @result [ <p>Hello</p> ]
358 * @example $("p").unbind( "click", function() { alert("Hello"); } )
359 * @before <p onclick="alert('Hello');">Hello</p>
360 * @result [ <p>Hello</p> ]
364 * @param String type (optional) An event type
365 * @param Function fn (optional) A function to unbind from the event on each of the set of matched elements
368 unbind: function( type, fn ) {
369 return this.each(function(){
370 jQuery.event.remove( this, type, fn );
375 * Trigger a type of event on every matched element. This will also cause
376 * the default action of the browser with the same name (if one exists)
377 * to be executed. For example, passing 'submit' to the trigger()
378 * function will also cause the browser to submit the form. This
379 * default action can be prevented by returning false from one of
380 * the functions bound to the event.
382 * You can also trigger custom events registered with bind.
384 * @example $("p").trigger("click")
385 * @before <p click="alert('hello')">Hello</p>
386 * @result alert('hello')
388 * @example $("p").click(function(event, a, b) {
389 * // when a normal click fires, a and b are undefined
390 * // for a trigger like below a refers too "foo" and b refers to "bar"
391 * }).trigger("click", ["foo", "bar"]);
392 * @desc Example of how to pass arbitrary data to an event
394 * @example $("p").bind("myEvent",function(event,message1,message2) {
395 * alert(message1 + ' ' + message2);
397 * $("p").trigger("myEvent",["Hello","World"]);
398 * @result alert('Hello World') // One for each paragraph
402 * @param String type An event type to trigger.
403 * @param Array data (optional) Additional data to pass as arguments (after the event object) to the event handler
406 trigger: function( type, data ) {
407 return this.each(function(){
408 jQuery.event.trigger( type, data, this );
413 * Toggle between two function calls every other click.
414 * Whenever a matched element is clicked, the first specified function
415 * is fired, when clicked again, the second is fired. All subsequent
416 * clicks continue to rotate through the two functions.
418 * Use unbind("click") to remove.
420 * @example $("p").toggle(function(){
421 * $(this).addClass("selected");
423 * $(this).removeClass("selected");
428 * @param Function even The function to execute on every even click.
429 * @param Function odd The function to execute on every odd click.
433 // Save reference to arguments for access in closure
436 return this.click(function(e) {
437 // Figure out which function to execute
438 this.lastToggle = 0 == this.lastToggle ? 1 : 0;
440 // Make sure that clicks stop
443 // and execute the function
444 return a[this.lastToggle].apply( this, [e] ) || false;
449 * A method for simulating hovering (moving the mouse on, and off,
450 * an object). This is a custom method which provides an 'in' to a
453 * Whenever the mouse cursor is moved over a matched
454 * element, the first specified function is fired. Whenever the mouse
455 * moves off of the element, the second specified function fires.
456 * Additionally, checks are in place to see if the mouse is still within
457 * the specified element itself (for example, an image inside of a div),
458 * and if it is, it will continue to 'hover', and not move out
459 * (a common error in using a mouseout event handler).
461 * @example $("p").hover(function(){
462 * $(this).addClass("hover");
464 * $(this).removeClass("hover");
469 * @param Function over The function to fire whenever the mouse is moved over a matched element.
470 * @param Function out The function to fire whenever the mouse is moved off of a matched element.
473 hover: function(f,g) {
475 // A private function for handling mouse 'hovering'
476 function handleHover(e) {
477 // Check if mouse(over|out) are still within the same parent element
478 var p = e.relatedTarget;
480 // Traverse up the tree
481 while ( p && p != this ) try { p = p.parentNode; } catch(e) { p = this; };
483 // If we actually just moused on to a sub-element, ignore it
484 if ( p == this ) return false;
486 // Execute the right function
487 return (e.type == "mouseover" ? f : g).apply(this, [e]);
490 // Bind the function to the two event listeners
491 return this.mouseover(handleHover).mouseout(handleHover);
495 * Bind a function to be executed whenever the DOM is ready to be
496 * traversed and manipulated. This is probably the most important
497 * function included in the event module, as it can greatly improve
498 * the response times of your web applications.
500 * In a nutshell, this is a solid replacement for using window.onload,
501 * and attaching a function to that. By using this method, your bound function
502 * will be called the instant the DOM is ready to be read and manipulated,
503 * which is when what 99.99% of all JavaScript code needs to run.
505 * There is one argument passed to the ready event handler: A reference to
506 * the jQuery function. You can name that argument whatever you like, and
507 * can therefore stick with the $ alias without risk of naming collisions.
509 * Please ensure you have no code in your <body> onload event handler,
510 * otherwise $(document).ready() may not fire.
512 * You can have as many $(document).ready events on your page as you like.
513 * The functions are then executed in the order they were added.
515 * @example $(document).ready(function(){ Your code here... });
517 * @example jQuery(function($) {
518 * // Your code using failsafe $ alias here...
520 * @desc Uses both the [[Core#.24.28_fn_.29|shortcut]] for $(document).ready() and the argument
521 * to write failsafe jQuery code using the $ alias, without relying on the
526 * @param Function fn The function to be executed when the DOM is ready.
528 * @see $.noConflict()
532 // Attach the listeners
535 // If the DOM is already ready
536 if ( jQuery.isReady )
537 // Execute the function immediately
538 f.apply( document, [jQuery] );
540 // Otherwise, remember the function for later
542 // Add the function to the wait list
543 jQuery.readyList.push( function() { return f.apply(this, [jQuery]); } );
551 * All the code that makes DOM Ready work nicely.
556 // Handle when the DOM is ready
558 // Make sure that the DOM is not already loaded
559 if ( !jQuery.isReady ) {
560 // Remember that the DOM is ready
561 jQuery.isReady = true;
563 // If there are functions bound, to execute
564 if ( jQuery.readyList ) {
565 // Execute all of them
566 jQuery.each( jQuery.readyList, function(){
567 this.apply( document );
570 // Reset the list of functions
571 jQuery.readyList = null;
573 // Remove event listener to avoid memory leak
574 if ( jQuery.browser.mozilla || jQuery.browser.opera )
575 document.removeEventListener( "DOMContentLoaded", jQuery.ready, false );
577 // Remove script element used by IE hack
578 if( !window.frames.length ) // don't remove if frames are present (#1187)
579 jQuery(window).load(function(){ jQuery("#__ie_init").remove(); });
585 * Bind a function to the scroll event of each matched element.
587 * @example $("p").scroll( function() { alert("Hello"); } );
588 * @before <p>Hello</p>
589 * @result <p onscroll="alert('Hello');">Hello</p>
593 * @param Function fn A function to bind to the scroll event on each of the matched elements.
598 * Bind a function to the submit event of each matched element.
600 * @example $("#myform").submit( function() {
601 * return $("input", this).val().length > 0;
603 * @before <form id="myform"><input /></form>
604 * @desc Prevents the form submission when the input has no value entered.
608 * @param Function fn A function to bind to the submit event on each of the matched elements.
613 * Trigger the submit event of each matched element. This causes all of the functions
614 * that have been bound to that submit event to be executed, and calls the browser's
615 * default submit action on the matching element(s). This default action can be prevented
616 * by returning false from one of the functions bound to the submit event.
618 * Note: This does not execute the submit method of the form element! If you need to
619 * submit the form via code, you have to use the DOM method, eg. $("form")[0].submit();
621 * @example $("form").submit();
622 * @desc Triggers all submit events registered to the matched form(s), and submits them.
630 * Bind a function to the focus event of each matched element.
632 * @example $("p").focus( function() { alert("Hello"); } );

634 * @result <p onfocus="alert('Hello');">Hello</p>
638 * @param Function fn A function to bind to the focus event on each of the matched elements.
643 * Trigger the focus event of each matched element. This causes all of the functions
644 * that have been bound to thet focus event to be executed.
646 * Note: This does not execute the focus method of the underlying elements! If you need to
647 * focus an element via code, you have to use the DOM method, eg. $("#myinput")[0].focus();
649 * @example $("p").focus();
650 * @before <p onfocus="alert('Hello');">Hello</p>
651 * @result alert('Hello');
659 * Bind a function to the keydown event of each matched element.
661 * @example $("p").keydown( function() { alert("Hello"); } );
662 * @before <p>Hello</p>

706 * @param Function fn A function to bind to the error event on each of the matched elements.
711 * Bind a function to the blur event of each matched element.
713 * @example $("p").blur( function() { alert("Hello"); } );
714 * @before <p>Hello</p>
715 * @result <p onblur="alert('Hello');">Hello</p>
719 * @param Function fn A function to bind to the blur event on each of the matched elements.
724 * Trigger the blur event of each matched element. This causes all of the functions
725 * that have been bound to that blur event to be executed, and calls the browser's
726 * default blur action on the matching element(s). This default action can be prevented
727 * by returning false from one of the functions bound to the blur event.
729 * Note: This does not execute the blur method of the underlying elements! If you need to
730 * blur an element via code, you have to use the DOM method, eg. $("#myinput")[0].blur();
732 * @example $("p").blur();
733 * @before <p onblur="alert('Hello');">Hello</p>
