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.

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 ) {

198 // Return a 'clean' array
199 jQuery.map( this, function(a){ return a } ) :

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';});

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 ) {

236 index: function( obj ) {
238 this.each(function(i){
239 if ( this == obj ) pos = i;
245 * Access a property on the first matched element.
246 * This method makes it easy to retreive a property value
247 * from the first matched element.
249 * @example $("img").attr("src");
250 * @before <img src="test.jpg"/>
255 * @param String name The name of the property to access.
260 * Set a hash of key/value object properties to all matched elements.
261 * This serves as the best way to set a large number of properties
262 * on all matched elements.
264 * @example $("img").attr({ src: "test.jpg", alt: "Test Image" });
266 * @result <img src="test.jpg" alt="Test Image"/>
268 * @test var pass = true;
269 * $("div").attr({foo: 'baz', zoo: 'ping'}).each(function(){
270 * if ( this.getAttribute('foo') != "baz" && this.getAttribute('zoo') != "ping" ) pass = false;
272 * ok( pass, "Set Multiple Attributes" );
276 * @param Hash prop A set of key/value pairs to set as object properties.
281 * Set a single property to a value, on all matched elements.
283 * @example $("img").attr("src","test.jpg");
285 * @result <img src="test.jpg"/>
287 * @test var div = $("div");
288 * div.attr("foo", "bar");
290 * for ( var i = 0; i < div.size(); i++ ) {
291 * if ( div.get(i).getAttribute('foo') != "bar" ) pass = false;
293 * ok( pass, "Set Attribute" );
297 * @param String key The name of the property to set.
298 * @param Object value The value to set the property to.

317 type ? this.style : this,
322 // Look for the case where we're accessing a style value
323 jQuery[ type || "attr" ]( this[0], key );
327 * Access a style property on the first matched element.
328 * This method makes it easy to retreive a style property value
329 * from the first matched element.
331 * @example $("p").css("red");
332 * @before <p style="color:red;">Test Paragraph.</p>
337 * @param String name The name of the property to access.
342 * Set a hash of key/value style properties to all matched elements.
343 * This serves as the best way to set a large number of style properties
344 * on all matched elements.
346 * @example $("p").css({ color: "red", background: "blue" });
347 * @before <p>Test Paragraph.</p>
348 * @result <p style="color:red; background:blue;">Test Paragraph.</p>
352 * @param Hash prop A set of key/value pairs to set as style properties.
357 * Set a single style property to a value, on all matched elements.
359 * @example $("p").css("color","red");
360 * @before <p>Test Paragraph.</p>
361 * @result <p style="color:red;">Test Paragraph.</p>
365 * @param String key The name of the property to set.
366 * @param Object value The value to set the property to.
369 css: function( key, value ) {
370 return this.attr( key, value, "curCSS" );
374 * Retreive the text contents of all matched elements. The result is
375 * a string that contains the combined text contents of all matched
376 * elements. This method works on both HTML and XML documents.
378 * @example $("p").text();
379 * @before <p>Test Paragraph.</p>
380 * @result Test Paragraph.
389 for ( var j = 0; j < e.length; j++ ) {

391 for ( var i = 0; i < r.length; i++ )
392 t += r[i].nodeType != 1 ?
393 r[i].nodeValue : jQuery.fn.text([ r[i] ]);
399 * Wrap all matched elements with a structure of other elements.
400 * This wrapping process is most useful for injecting additional
401 * stucture into a document, without ruining the original semantic
402 * qualities of a document.
404 * The way that is works is that it goes through the first element argument
405 * provided and finds the deepest element within the structure - it is that
406 * element that will en-wrap everything else.
408 * @example $("p").wrap("<div class='wrap'></div>");
409 * @before <p>Test Paragraph.</p>
410 * @result <div class='wrap'><p>Test Paragraph.</p></div>
414 * @any String html A string of HTML, that will be created on the fly and wrapped around the target.
415 * @any Element elem A DOM element that will be wrapped.
416 * @any Array<Element> elems An array of elements, the first of which will be wrapped.
417 * @any Object obj Any object, converted to a string, then a text node.
418 * @cat DOM/Manipulation
421 // The elements to wrap the target around
422 var a = jQuery.clean(arguments);
424 // Wrap each of the matched elements individually
425 return this.each(function(){
426 // Clone the structure that we're using to wrap
427 var b = a[0].cloneNode(true);
429 // Insert it before the element to be wrapped
430 this.parentNode.insertBefore( b, this );
432 // Find he deepest point in the wrap structure
433 while ( b.firstChild )
436 // Move the matched element to within the wrap structure
437 b.appendChild( this );
442 * Append any number of elements to the inside of all matched elements.
443 * This operation is similar to doing an appendChild to all the
444 * specified elements, adding them into the document.
446 * @example $("p").append("<b>Hello</b>");
447 * @before <p>I would like to say: </p>
448 * @result <p>I would like to say: <b>Hello</b></p>
452 * @any String html A string of HTML, that will be created on the fly and appended to the target.
453 * @any Element elem A DOM element that will be appended.
454 * @any Array<Element> elems An array of elements, all of which will be appended.
455 * @any Object obj Any object, converted to a string, then a text node.
456 * @cat DOM/Manipulation
459 return this.domManip(arguments, true, 1, function(a){
460 this.appendChild( a );
465 * Prepend any number of elements to the inside of all matched elements.
466 * This operation is the best way to insert a set of elements inside, at the
467 * beginning, of all the matched element.
469 * @example $("p").prepend("<b>Hello</b>");
470 * @before <p>, how are you?</p>
471 * @result <p><b>Hello</b>, how are you?</p>
475 * @any String html A string of HTML, that will be created on the fly and prepended to the target.
476 * @any Element elem A DOM element that will be prepended.
477 * @any Array<Element> elems An array of elements, all of which will be prepended.
478 * @any Object obj Any object, converted to a string, then a text node.
479 * @cat DOM/Manipulation
481 prepend: function() {
482 return this.domManip(arguments, true, -1, function(a){
483 this.insertBefore( a, this.firstChild );
488 * Insert any number of elements before each of the matched elements.
490 * @example $("p").before("<b>Hello</b>");
491 * @before <p>how are you?</p>
492 * @result <b>Hello</b><p>how are you?</p>
496 * @any String html A string of HTML, that will be created on the fly and inserted.
497 * @any Element elem A DOM element that will beinserted.
498 * @any Array<Element> elems An array of elements, all of which will be inserted.
499 * @any Object obj Any object, converted to a string, then a text node.
500 * @cat DOM/Manipulation
503 return this.domManip(arguments, false, 1, function(a){
504 this.parentNode.insertBefore( a, this );
509 * Insert any number of elements after each of the matched elements.
511 * @example $("p").after("<p>I'm doing fine.</p>");
512 * @before <p>How are you?</p>
513 * @result <p>How are you?</p><p>I'm doing fine.</p>
517 * @any String html A string of HTML, that will be created on the fly and inserted.
518 * @any Element elem A DOM element that will beinserted.
519 * @any Array<Element> elems An array of elements, all of which will be inserted.
520 * @any Object obj Any object, converted to a string, then a text node.
521 * @cat DOM/Manipulation
524 return this.domManip(arguments, false, -1, function(a){
525 this.parentNode.insertBefore( a, this.nextSibling );
530 * End the most recent 'destructive' operation, reverting the list of matched elements
531 * back to its previous state. After an end operation, the list of matched elements will
532 * revert to the last state of matched elements.
534 * @example $("p").find("span").end();
535 * @before <p><span>Hello</span>, how are you?</p>
536 * @result $("p").find("span").end() == [ <p>...</p> ]
540 * @cat DOM/Traversing
543 return this.get( this.stack.pop() );
547 * Searches for all elements that match the specified expression.
548 * This method is the optimal way of finding additional descendant
549 * elements with which to process.
551 * All searching is done using a jQuery expression. The expression can be
552 * written using CSS 1-3 Selector syntax, or basic XPath.
554 * @example $("p").find("span");
555 * @before <p><span>Hello</span>, how are you?</p>
556 * @result $("p").find("span") == [ <span>Hello</span> ]
560 * @param String expr An expression to search with.
561 * @cat DOM/Traversing
564 return this.pushStack( jQuery.map( this, function(a){
565 return jQuery.find(t,a);
569 clone: function(deep) {
570 return this.pushStack( jQuery.map( this, function(a){
571 return a.cloneNode( deep != undefined ? deep : true );
576 * Removes all elements from the set of matched elements that do not
577 * match the specified expression. This method is used to narrow down
578 * the results of a search.
580 * All searching is done using a jQuery expression. The expression
581 * can be written using CSS 1-3 Selector syntax, or basic XPath.
583 * @example $("p").filter(".selected")
584 * @before <p class="selected">Hello</p><p>How are you?</p>
585 * @result $("p").filter(".selected") == [ <p class="selected">Hello</p> ]
589 * @param String expr An expression to search with.
590 * @cat DOM/Traversing
594 * Removes all elements from the set of matched elements that do not
595 * match at least one of the expressions passed to the function. This
596 * method is used when you want to filter the set of matched elements
597 * through more than one expression.
599 * Elements will be retained in the jQuery object if they match at
600 * least one of the expressions passed.
602 * @example $("p").filter([".selected", ":first"])
603 * @before <p>Hello</p><p>Hello Again</p><p class="selected">And Again</p>
604 * @result $("p").filter([".selected", ":first"]) == [ <p>Hello</p>, <p class="selected">And Again</p> ]
608 * @param Array<String> exprs A set of expressions to evaluate against
609 * @cat DOM/Traversing

623 t.constructor == Function &&
624 jQuery.grep( this, t ) ||
626 jQuery.filter(t,this).r, arguments );
630 * Removes the specified Element from the set of matched elements. This
631 * method is used to remove a single Element from a jQuery object.
633 * @example $("p").not( document.getElementById("selected") )
634 * @before <p>Hello</p><p id="selected">Hello Again</p>
635 * @result [ <p>Hello</p> ]
639 * @param Element el An element to remove from the set
640 * @cat DOM/Traversing
644 * Removes elements matching the specified expression from the set
645 * of matched elements. This method is used to remove one or more
646 * elements from a jQuery object.
648 * @example $("p").not("#selected")
649 * @before <p>Hello</p><p id="selected">Hello Again</p>
650 * @result [ <p>Hello</p> ]
654 * @param String expr An expression with which to remove matching elements
655 * @cat DOM/Traversing
658 return this.pushStack( t.constructor == String ?
659 jQuery.filter(t,this,false).r :
660 jQuery.grep(this,function(a){ return a != t; }), arguments );
664 * Adds the elements matched by the expression to the jQuery object. This
665 * can be used to concatenate the result sets of two expressions.
667 * @example $("p").add("span")
668 * @before <p>Hello</p><p><span>Hello Again</span></p>
669 * @result [ <p>Hello</p>, <span>Hello Again</span> ]
673 * @param String expr An expression whose matched elements are added
674 * @cat DOM/Traversing
678 * Adds each of the Elements in the array to the set of matched elements.
679 * This is used to add a set of Elements to a jQuery object.
681 * @example $("p").add([document.getElementById("a"), document.getElementById("b")])
682 * @before <p>Hello</p><p><span id="a">Hello Again</span><span id="b">And Again</span></p>
683 * @result [ <p>Hello</p>, <span id="a">Hello Again</span>, <span id="b">And Again</span> ]
687 * @param Array<Element> els An array of Elements to add
692 * Adds a single Element to the set of matched elements. This is used to
693 * add a single Element to a jQuery object.
695 * @example $("p").add( document.getElementById("a") )
696 * @before <p>Hello</p><p><span id="a">Hello Again</span></p>
697 * @result [ <p>Hello</p>, <span id="a">Hello Again</span> ]
701 * @param Element el An Element to add

2585 * @example $("form").bind( "submit", function() { e.stopPropogation(); } )
2589 * @param String type An event type
2590 * @param Function fn A function to bind to the event on each of the set of matched elements

2600 * The opposite of bind, removes a bound event from each of the matched
2601 * elements. You must pass the identical function that was used in the original
2604 * @example $("p").unbind( "click", function() { alert("Hello"); } )
2605 * @before <p onclick="alert('Hello');">Hello</p>
2606 * @result [ <p>Hello</p> ]
2610 * @param String type An event type
2611 * @param Function fn A function to unbind from the event on each of the set of matched elements
2616 * Removes all bound events of a particular type from each of the matched
2619 * @example $("p").unbind( "click" )
2620 * @before <p onclick="alert('Hello');">Hello</p>
2621 * @result [ <p>Hello</p> ]
2625 * @param String type An event type
2630 * Removes all bound events from each of the matched elements.

2640 unbind: function( type, fn ) {
2641 jQuery.event.remove( this, type, fn );
2645 * Trigger a type of event on every matched element.
2647 * @example $("p").trigger("click")
2648 * @before <p click="alert('hello')">Hello</p>
2649 * @result alert('hello')
2653 * @param String type An event type to trigger.
