99 * The current SVN version of jQuery.
110 * The number of elements currently matched.
112 * @example $("img").length;
113 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
116 * @test cmpOK( $("div").length, "==", 2, "Get Number of Elements Found" );
125 * The number of elements currently matched.
127 * @example $("img").size();
128 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
131 * @test cmpOK( $("div").size(), "==", 2, "Get Number of Elements Found" );
142 * Access all matched elements. This serves as a backwards-compatible
143 * way of accessing all matched elements (other than the jQuery object
144 * itself, which is, in fact, an array of elements).
146 * @example $("img").get();
147 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
148 * @result [ <img src="test1.jpg"/> <img src="test2.jpg"/> ]
150 * @test isSet( $("div").get(), q("main","foo"), "Get All Elements" );
153 * @type Array<Element>
158 * Access a single matched element. num is used to access the
159 * Nth element matched.
161 * @example $("img").get(1);
162 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
163 * @result [ <img src="test1.jpg"/> ]
165 * @test cmpOK( $("div").get(0), "==", document.getElementById("main"), "Get A Single Element" );
169 * @param Number num Access the element in the Nth position.
174 * Set the jQuery object to an array of elements.
176 * @example $("img").get([ document.body ]);
177 * @result $("img").get() == [ document.body ]
182 * @param Elements elems An array of elements
185 get: function( num ) {
186 // Watch for when an array (of elements) is passed in
187 if ( num && num.constructor == Array ) {
189 // Use a tricky hack to make the jQuery object
190 // look and feel like an array
192 [].push.apply( this, num );
196 return num == undefined ?
198 // Return a 'clean' array
199 jQuery.map( this, function(a){ return a } ) :
201 // Return just the object
206 * Execute a function within the context of every matched element.
207 * This means that every time the passed-in function is executed
208 * (which is once for every element matched) the 'this' keyword
209 * points to the specific element.
211 * Additionally, the function, when executed, is passed a single
212 * argument representing the position of the element in the matched
215 * @example $("img").each(function(){ this.src = "test.jpg"; });
216 * @before <img/> <img/>
217 * @result <img src="test.jpg"/> <img src="test.jpg"/>
219 * @test var div = $("div");
220 * div.each(function(){this.foo = 'zoo';});
222 * for ( var i = 0; i < div.size(); i++ ) {
223 * if ( div.get(i).foo != "zoo" ) pass = false;
225 * ok( pass, "Execute a function, Relative" );
229 * @param Function fn A function to execute
232 each: function( fn, args ) {
233 return jQuery.each( this, fn, args );
237 * Access a property on the first matched element.
238 * This method makes it easy to retreive a property value
239 * from the first matched element.
241 * @example $("img").attr("src");
242 * @before <img src="test.jpg"/>
247 * @param String name The name of the property to access.
252 * Set a hash of key/value object properties to all matched elements.
253 * This serves as the best way to set a large number of properties
254 * on all matched elements.
256 * @example $("img").attr({ src: "test.jpg", alt: "Test Image" });
258 * @result <img src="test.jpg" alt="Test Image"/>
260 * @test var div = $("div");
261 * div.attr({foo: 'baz', zoo: 'ping'});
263 * for ( var i = 0; i < div.size(); i++ ) {
264 * if ( div.get(i).foo != "baz" && div.get(i).zoo != "ping" ) pass = false;
266 * ok( pass, "Set Multiple Attributes" );
270 * @param Hash prop A set of key/value pairs to set as object properties.
275 * Set a single property to a value, on all matched elements.
277 * @example $("img").attr("src","test.jpg");
279 * @result <img src="test.jpg"/>
281 * @test var div = $("div");
282 * div.attr("foo", "bar");
284 * for ( var i = 0; i < div.size(); i++ ) {
285 * if ( div.get(i).foo != "bar" ) pass = false;
287 * ok( pass, "Set Attribute" );
291 * @param String key The name of the property to set.
292 * @param Object value The value to set the property to.

311 type ? this.style : this,
316 // Look for the case where we're accessing a style value
317 jQuery[ type || "attr" ]( this[0], key );
321 * Access a style property on the first matched element.
322 * This method makes it easy to retreive a style property value
323 * from the first matched element.
325 * @example $("p").css("red");
326 * @before <p style="color:red;">Test Paragraph.</p>
331 * @param String name The name of the property to access.
336 * Set a hash of key/value style properties to all matched elements.
337 * This serves as the best way to set a large number of style properties
338 * on all matched elements.
340 * @example $("p").css({ color: "red", background: "blue" });
341 * @before <p>Test Paragraph.</p>
342 * @result <p style="color:red; background:blue;">Test Paragraph.</p>
346 * @param Hash prop A set of key/value pairs to set as style properties.
351 * Set a single style property to a value, on all matched elements.
353 * @example $("p").css("color","red");
354 * @before <p>Test Paragraph.</p>
355 * @result <p style="color:red;">Test Paragraph.</p>
359 * @param String key The name of the property to set.
360 * @param Object value The value to set the property to.
363 css: function( key, value ) {
364 return this.attr( key, value, "curCSS" );
368 * Retreive the text contents of all matched elements. The result is
369 * a string that contains the combined text contents of all matched
370 * elements. This method works on both HTML and XML documents.
372 * @example $("p").text();
373 * @before <p>Test Paragraph.</p>
374 * @result Test Paragraph.
383 for ( var j = 0; j < e.length; j++ ) {
384 var r = e[j].childNodes;
385 for ( var i = 0; i < r.length; i++ )
386 t += r[i].nodeType != 1 ?
387 r[i].nodeValue : jQuery.fn.text([ r[i] ]);
393 * Wrap all matched elements with a structure of other elements.
394 * This wrapping process is most useful for injecting additional
395 * stucture into a document, without ruining the original semantic
396 * qualities of a document.
398 * The way that is works is that it goes through the first element argument
399 * provided and finds the deepest element within the structure - it is that
400 * element that will en-wrap everything else.
402 * @example $("p").wrap("<div class='wrap'></div>");
403 * @before <p>Test Paragraph.</p>
404 * @result <div class='wrap'><p>Test Paragraph.</p></div>
408 * @any String html A string of HTML, that will be created on the fly and wrapped around the target.
409 * @any Element elem A DOM element that will be wrapped.
410 * @any Array<Element> elems An array of elements, the first of which will be wrapped.
411 * @any Object obj Any object, converted to a string, then a text node.
412 * @cat DOM/Manipulation
415 // The elements to wrap the target around
416 var a = jQuery.clean(arguments);
418 // Wrap each of the matched elements individually
419 return this.each(function(){
420 // Clone the structure that we're using to wrap
421 var b = a[0].cloneNode(true);
423 // Insert it before the element to be wrapped
424 this.parentNode.insertBefore( b, this );
426 // Find he deepest point in the wrap structure
427 while ( b.firstChild )
430 // Move the matched element to within the wrap structure
431 b.appendChild( this );
436 * Append any number of elements to the inside of all matched elements.
437 * This operation is similar to doing an appendChild to all the
438 * specified elements, adding them into the document.
440 * @example $("p").append("<b>Hello</b>");
441 * @before <p>I would like to say: </p>
442 * @result <p>I would like to say: <b>Hello</b></p>
446 * @any String html A string of HTML, that will be created on the fly and appended to the target.
447 * @any Element elem A DOM element that will be appended.
448 * @any Array<Element> elems An array of elements, all of which will be appended.
449 * @any Object obj Any object, converted to a string, then a text node.
450 * @cat DOM/Manipulation
453 return this.domManip(arguments, true, 1, function(a){
454 this.appendChild( a );
459 * Prepend any number of elements to the inside of all matched elements.
460 * This operation is the best way to insert a set of elements inside, at the
461 * beginning, of all the matched element.
463 * @example $("p").prepend("<b>Hello</b>");
464 * @before <p>, how are you?</p>
465 * @result <p><b>Hello</b>, how are you?</p>
469 * @any String html A string of HTML, that will be created on the fly and prepended to the target.
470 * @any Element elem A DOM element that will be prepended.
471 * @any Array<Element> elems An array of elements, all of which will be prepended.
472 * @any Object obj Any object, converted to a string, then a text node.
473 * @cat DOM/Manipulation
475 prepend: function() {
476 return this.domManip(arguments, true, -1, function(a){
477 this.insertBefore( a, this.firstChild );
482 * Insert any number of elements before each of the matched elements.
484 * @example $("p").before("<b>Hello</b>");
485 * @before <p>how are you?</p>
486 * @result <b>Hello</b><p>how are you?</p>
490 * @any String html A string of HTML, that will be created on the fly and inserted.
491 * @any Element elem A DOM element that will beinserted.
492 * @any Array<Element> elems An array of elements, all of which will be inserted.
493 * @any Object obj Any object, converted to a string, then a text node.
494 * @cat DOM/Manipulation
497 return this.domManip(arguments, false, 1, function(a){
498 this.parentNode.insertBefore( a, this );
503 * Insert any number of elements after each of the matched elements.
505 * @example $("p").after("<p>I'm doing fine.</p>");
506 * @before <p>How are you?</p>
507 * @result <p>How are you?</p><p>I'm doing fine.</p>
511 * @any String html A string of HTML, that will be created on the fly and inserted.
512 * @any Element elem A DOM element that will beinserted.
513 * @any Array<Element> elems An array of elements, all of which will be inserted.
514 * @any Object obj Any object, converted to a string, then a text node.
515 * @cat DOM/Manipulation
518 return this.domManip(arguments, false, -1, function(a){
519 this.parentNode.insertBefore( a, this.nextSibling );
524 * End the most recent 'destructive' operation, reverting the list of matched elements
525 * back to its previous state. After an end operation, the list of matched elements will
526 * revert to the last state of matched elements.
528 * @example $("p").find("span").end();
529 * @before <p><span>Hello</span>, how are you?</p>
530 * @result $("p").find("span").end() == [ <p>...</p> ]
534 * @cat DOM/Traversing
537 return this.get( this.stack.pop() );
541 * Searches for all elements that match the specified expression.
542 * This method is the optimal way of finding additional descendant
543 * elements with which to process.
545 * All searching is done using a jQuery expression. The expression can be
546 * written using CSS 1-3 Selector syntax, or basic XPath.
548 * @example $("p").find("span");
549 * @before <p><span>Hello</span>, how are you?</p>
550 * @result $("p").find("span") == [ <span>Hello</span> ]
554 * @param String expr An expression to search with.
555 * @cat DOM/Traversing
558 return this.pushStack( jQuery.map( this, function(a){
559 return jQuery.find(t,a);
564 * Removes all elements from the set of matched elements that do not
565 * match the specified expression. This method is used to narrow down
566 * the results of a search.
568 * All searching is done using a jQuery expression. The expression
569 * can be written using CSS 1-3 Selector syntax, or basic XPath.
571 * @example $("p").filter(".selected")
572 * @before <p class="selected">Hello</p><p>How are you?</p>
573 * @result $("p").filter(".selected") == [ <p class="selected">Hello</p> ]
577 * @param String expr An expression to search with.
578 * @cat DOM/Traversing
582 * Removes all elements from the set of matched elements that do not
583 * match at least one of the expressions passed to the function. This
584 * method is used when you want to filter the set of matched elements
585 * through more than one expression.
587 * Elements will be retained in the jQuery object if they match at
588 * least one of the expressions passed.
590 * @example $("p").filter([".selected", ":first"])
591 * @before <p>Hello</p><p>Hello Again</p><p class="selected">And Again</p>
592 * @result $("p").filter([".selected", ":first"]) == [ <p>Hello</p>, <p class="selected">And Again</p> ]
596 * @param Array<String> exprs A set of expressions to evaluate against
597 * @cat DOM/Traversing
599 filter: function(t) {

609 ( t ? this.get() : [] ) ||
611 t.constructor == Function &&
612 jQuery.grep( this, t ) ||
614 jQuery.filter(t,this).r, arguments );
618 * Removes the specified Element from the set of matched elements. This
619 * method is used to remove a single Element from a jQuery object.
621 * @example $("p").not( document.getElementById("selected") )
622 * @before <p>Hello</p><p id="selected">Hello Again</p>
623 * @result [ <p>Hello</p> ]
627 * @param Element el An element to remove from the set
628 * @cat DOM/Traversing
632 * Removes elements matching the specified expression from the set
633 * of matched elements. This method is used to remove one or more
634 * elements from a jQuery object.
636 * @example $("p").not("#selected")
637 * @before <p>Hello</p><p id="selected">Hello Again</p>
638 * @result [ <p>Hello</p> ]
642 * @param String expr An expression with which to remove matching elements
643 * @cat DOM/Traversing
646 return this.pushStack( t.constructor == String ?
647 jQuery.filter(t,this,false).r :
648 jQuery.grep(this,function(a){ return a != t; }), arguments );
652 * Adds the elements matched by the expression to the jQuery object. This
653 * can be used to concatenate the result sets of two expressions.
655 * @example $("p").add("span")
656 * @before <p>Hello</p><p><span>Hello Again</span></p>
657 * @result [ <p>Hello</p>, <span>Hello Again</span> ]
661 * @param String expr An expression whose matched elements are added
662 * @cat DOM/Traversing
666 * Adds each of the Elements in the array to the set of matched elements.
667 * This is used to add a set of Elements to a jQuery object.
669 * @example $("p").add([document.getElementById("a"), document.getElementById("b")])
670 * @before <p>Hello</p><p><span id="a">Hello Again</span><span id="b">And Again</span></p>
671 * @result [ <p>Hello</p>, <span id="a">Hello Again</span>, <span id="b">And Again</span> ]
675 * @param Array<Element> els An array of Elements to add
680 * Adds a single Element to the set of matched elements. This is used to
681 * add a single Element to a jQuery object.
683 * @example $("p").add( document.getElementById("a") )
684 * @before <p>Hello</p><p><span id="a">Hello Again</span></p>
685 * @result [ <p>Hello</p>, <span id="a">Hello Again</span> ]
689 * @param Element el An Element to add
693 return this.pushStack( jQuery.merge( this, t.constructor == String ?

703 * @param {String} expr The expression with which to filter
708 return expr ? jQuery.filter(expr,this).r.length > 0 : this.length > 0;
717 * @param Boolean table
719 * @param Function fn The function doing the DOM manipulation.

2561 * @example $("form").bind( "submit", function() { e.preventDefault(); } )
2563 * Stop an event from bubbling by using the stopPropogation method.
2565 * @example $("form").bind( "submit", function() { e.stopPropogation(); } )
2569 * @param String type An event type
2570 * @param Function fn A function to bind to the event on each of the set of matched elements

2580 * The opposite of bind, removes a bound event from each of the matched
2581 * elements. You must pass the identical function that was used in the original
2584 * @example $("p").unbind( "click", function() { alert("Hello"); } )

2586 * @result [ <p>Hello</p> ]
2590 * @param String type An event type
2591 * @param Function fn A function to unbind from the event on each of the set of matched elements
2596 * Removes all bound events of a particular type from each of the matched
2599 * @example $("p").unbind( "click" )
2600 * @before <p onclick="alert('Hello');">Hello</p>
2601 * @result [ <p>Hello</p> ]
2605 * @param String type An event type
2610 * Removes all bound events from each of the matched elements.
2612 * @example $("p").unbind()
2613 * @before <p onclick="alert('Hello');">Hello</p>
2614 * @result [ <p>Hello</p> ]
2620 unbind: function( type, fn ) {
2621 jQuery.event.remove( this, type, fn );
2625 * Trigger a type of event on every matched element.
2627 * @example $("p").trigger("click")
2628 * @before <p click="alert('hello')">Hello</p>
2629 * @result alert('hello')
2633 * @param String type An event type to trigger.
