80 * The current SVN version of jQuery.
91 * The number of elements currently matched.
93 * @example $("img").length;

97 * @test cmpOK( $("div").length, "==", 2, "Get Number of Elements Found" );
106 * The number of elements currently matched.

109 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
112 * @test cmpOK( $("div").size(), "==", 2, "Get Number of Elements Found" );
123 * Access all matched elements. This serves as a backwards-compatible
124 * way of accessing all matched elements (other than the jQuery object
125 * itself, which is, in fact, an array of elements).
127 * @example $("img").get();
128 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
129 * @result [ <img src="test1.jpg"/> <img src="test2.jpg"/> ]
131 * @test isSet( $("div").get(), q("main","foo"), "Get All Elements" );
134 * @type Array<Element>
139 * Access a single matched element. num is used to access the
140 * Nth element matched.
142 * @example $("img").get(1);
143 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
144 * @result [ <img src="test1.jpg"/> ]
146 * @test cmpOK( $("div").get(0), "==", document.getElementById("main"), "Get A Single Element" );
150 * @param Number num Access the element in the Nth position.
155 * Set the jQuery object to an array of elements.
157 * @example $("img").get([ document.body ]);
158 * @result $("img").get() == [ document.body ]
163 * @param Elements elems An array of elements
166 get: function( num ) {
167 // Watch for when an array (of elements) is passed in
168 if ( num && num.constructor == Array ) {
170 // Use a tricky hack to make the jQuery object
171 // look and feel like an array
173 [].push.apply( this, num );

179 // Return a 'clean' array
180 jQuery.map( this, function(a){ return a } ) :
182 // Return just the object
187 * Execute a function within the context of every matched element.
188 * This means that every time the passed-in function is executed
189 * (which is once for every element matched) the 'this' keyword
190 * points to the specific element.
192 * Additionally, the function, when executed, is passed a single
193 * argument representing the position of the element in the matched
196 * @example $("img").each(function(){
197 * this.src = "test.jpg";
199 * @before <img/> <img/>
200 * @result <img src="test.jpg"/> <img src="test.jpg"/>

203 * alert( "Image #" + i + " is " + this );
205 * @before <img/> <img/>
206 * @result <img src="test.jpg"/> <img src="test.jpg"/>
208 * @test var div = $("div");

212 * if ( div.get(i).foo != "zoo" ) pass = false;
214 * ok( pass, "Execute a function, Relative" );
218 * @param Function fn A function to execute
221 each: function( fn, args ) {

227 this.each(function(i){
228 if ( this == obj ) pos = i;
234 * Access a property on the first matched element.
235 * This method makes it easy to retreive a property value
236 * from the first matched element.
238 * @example $("img").attr("src");
239 * @before <img src="test.jpg"/>
244 * @param String name The name of the property to access.
249 * Set a hash of key/value object properties to all matched elements.
250 * This serves as the best way to set a large number of properties
251 * on all matched elements.
253 * @example $("img").attr({ src: "test.jpg", alt: "Test Image" });
255 * @result <img src="test.jpg" alt="Test Image"/>

265 * @param Hash prop A set of key/value pairs to set as object properties.
270 * Set a single property to a value, on all matched elements.
272 * @example $("img").attr("src","test.jpg");
274 * @result <img src="test.jpg"/>
276 * @test var div = $("div");
277 * div.attr("foo", "bar");
279 * for ( var i = 0; i < div.size(); i++ ) {
280 * if ( div.get(i).getAttribute('foo') != "bar" ) pass = false;
282 * ok( pass, "Set Attribute" );
286 * @param String key The name of the property to set.
287 * @param Object value The value to set the property to.

311 // Look for the case where we're accessing a style value
312 jQuery[ type || "attr" ]( this[0], key );
316 * Access a style property on the first matched element.
317 * This method makes it easy to retreive a style property value
318 * from the first matched element.
320 * @example $("p").css("red");
321 * @before <p style="color:red;">Test Paragraph.</p>
326 * @param String name The name of the property to access.
331 * Set a hash of key/value style properties to all matched elements.
332 * This serves as the best way to set a large number of style properties
333 * on all matched elements.
335 * @example $("p").css({ color: "red", background: "blue" });
336 * @before <p>Test Paragraph.</p>
337 * @result <p style="color:red; background:blue;">Test Paragraph.</p>
341 * @param Hash prop A set of key/value pairs to set as style properties.
346 * Set a single style property to a value, on all matched elements.
348 * @example $("p").css("color","red");
349 * @before <p>Test Paragraph.</p>
350 * @result <p style="color:red;">Test Paragraph.</p>
354 * @param String key The name of the property to set.
355 * @param Object value The value to set the property to.
358 css: function( key, value ) {
359 return this.attr( key, value, "curCSS" );
363 * Retreive the text contents of all matched elements. The result is
364 * a string that contains the combined text contents of all matched
365 * elements. This method works on both HTML and XML documents.
367 * @example $("p").text();
368 * @before <p>Test Paragraph.</p>
369 * @result Test Paragraph.

381 t += r[i].nodeType != 1 ?
382 r[i].nodeValue : jQuery.fn.text([ r[i] ]);
388 * Wrap all matched elements with a structure of other elements.
389 * This wrapping process is most useful for injecting additional
390 * stucture into a document, without ruining the original semantic
391 * qualities of a document.
393 * The way that is works is that it goes through the first element argument
394 * provided and finds the deepest element within the structure - it is that
395 * element that will en-wrap everything else.
397 * @example $("p").wrap("<div class='wrap'></div>");
398 * @before <p>Test Paragraph.</p>
399 * @result <div class='wrap'><p>Test Paragraph.</p></div>
403 * @any String html A string of HTML, that will be created on the fly and wrapped around the target.
404 * @any Element elem A DOM element that will be wrapped.
405 * @any Array<Element> elems An array of elements, the first of which will be wrapped.
406 * @any Object obj Any object, converted to a string, then a text node.
407 * @cat DOM/Manipulation
410 // The elements to wrap the target around
411 var a = jQuery.clean(arguments);
413 // Wrap each of the matched elements individually
414 return this.each(function(){
415 // Clone the structure that we're using to wrap
416 var b = a[0].cloneNode(true);
418 // Insert it before the element to be wrapped
419 this.parentNode.insertBefore( b, this );
421 // Find he deepest point in the wrap structure
422 while ( b.firstChild )
425 // Move the matched element to within the wrap structure
426 b.appendChild( this );
431 * Append any number of elements to the inside of all matched elements.
432 * This operation is similar to doing an appendChild to all the
433 * specified elements, adding them into the document.
435 * @example $("p").append("<b>Hello</b>");
436 * @before <p>I would like to say: </p>
437 * @result <p>I would like to say: <b>Hello</b></p>
441 * @any String html A string of HTML, that will be created on the fly and appended to the target.
442 * @any Element elem A DOM element that will be appended.
443 * @any Array<Element> elems An array of elements, all of which will be appended.
444 * @any Object obj Any object, converted to a string, then a text node.
445 * @cat DOM/Manipulation
448 return this.domManip(arguments, true, 1, function(a){
449 this.appendChild( a );
454 * Prepend any number of elements to the inside of all matched elements.
455 * This operation is the best way to insert a set of elements inside, at the
456 * beginning, of all the matched element.
458 * @example $("p").prepend("<b>Hello</b>");
459 * @before <p>, how are you?</p>
460 * @result <p><b>Hello</b>, how are you?</p>
464 * @any String html A string of HTML, that will be created on the fly and prepended to the target.
465 * @any Element elem A DOM element that will be prepended.
466 * @any Array<Element> elems An array of elements, all of which will be prepended.
467 * @any Object obj Any object, converted to a string, then a text node.
468 * @cat DOM/Manipulation
470 prepend: function() {
471 return this.domManip(arguments, true, -1, function(a){
472 this.insertBefore( a, this.firstChild );
477 * Insert any number of elements before each of the matched elements.
479 * @example $("p").before("<b>Hello</b>");
480 * @before <p>how are you?</p>
481 * @result <b>Hello</b><p>how are you?</p>
485 * @any String html A string of HTML, that will be created on the fly and inserted.
486 * @any Element elem A DOM element that will beinserted.
487 * @any Array<Element> elems An array of elements, all of which will be inserted.
488 * @any Object obj Any object, converted to a string, then a text node.
489 * @cat DOM/Manipulation
492 return this.domManip(arguments, false, 1, function(a){
493 this.parentNode.insertBefore( a, this );
498 * Insert any number of elements after each of the matched elements.
500 * @example $("p").after("<p>I'm doing fine.</p>");
501 * @before <p>How are you?</p>
502 * @result <p>How are you?</p><p>I'm doing fine.</p>
506 * @any String html A string of HTML, that will be created on the fly and inserted.
507 * @any Element elem A DOM element that will beinserted.
508 * @any Array<Element> elems An array of elements, all of which will be inserted.
509 * @any Object obj Any object, converted to a string, then a text node.
510 * @cat DOM/Manipulation
513 return this.domManip(arguments, false, -1, function(a){
514 this.parentNode.insertBefore( a, this.nextSibling );
519 * End the most recent 'destructive' operation, reverting the list of matched elements
520 * back to its previous state. After an end operation, the list of matched elements will
521 * revert to the last state of matched elements.
523 * @example $("p").find("span").end();
524 * @before <p><span>Hello</span>, how are you?</p>
525 * @result $("p").find("span").end() == [ <p>...</p> ]
529 * @cat DOM/Traversing
532 return this.get( this.stack.pop() );
536 * Searches for all elements that match the specified expression.
537 * This method is the optimal way of finding additional descendant
538 * elements with which to process.
540 * All searching is done using a jQuery expression. The expression can be
541 * written using CSS 1-3 Selector syntax, or basic XPath.
543 * @example $("p").find("span");
544 * @before <p><span>Hello</span>, how are you?</p>
545 * @result $("p").find("span") == [ <span>Hello</span> ]
549 * @param String expr An expression to search with.
550 * @cat DOM/Traversing
553 return this.pushStack( jQuery.map( this, function(a){
554 return jQuery.find(t,a);
558 clone: function(deep) {
559 return this.pushStack( jQuery.map( this, function(a){
560 return a.cloneNode( deep != undefined ? deep : true );
565 * Removes all elements from the set of matched elements that do not
566 * match the specified expression. This method is used to narrow down
567 * the results of a search.
569 * All searching is done using a jQuery expression. The expression
570 * can be written using CSS 1-3 Selector syntax, or basic XPath.
572 * @example $("p").filter(".selected")
573 * @before <p class="selected">Hello</p><p>How are you?</p>
574 * @result $("p").filter(".selected") == [ <p class="selected">Hello</p> ]
578 * @param String expr An expression to search with.
579 * @cat DOM/Traversing
583 * Removes all elements from the set of matched elements that do not
584 * match at least one of the expressions passed to the function. This
585 * method is used when you want to filter the set of matched elements
586 * through more than one expression.
588 * Elements will be retained in the jQuery object if they match at
589 * least one of the expressions passed.
591 * @example $("p").filter([".selected", ":first"])
592 * @before <p>Hello</p><p>Hello Again</p><p class="selected">And Again</p>
593 * @result $("p").filter([".selected", ":first"]) == [ <p>Hello</p>, <p class="selected">And Again</p> ]
597 * @param Array<String> exprs A set of expressions to evaluate against
598 * @cat DOM/Traversing

612 t.constructor == Function &&
613 jQuery.grep( this, t ) ||
615 jQuery.filter(t,this).r, arguments );
619 * Removes the specified Element from the set of matched elements. This
620 * method is used to remove a single Element from a jQuery object.
622 * @example $("p").not( document.getElementById("selected") )
623 * @before <p>Hello</p><p id="selected">Hello Again</p>
624 * @result [ <p>Hello</p> ]
628 * @param Element el An element to remove from the set
629 * @cat DOM/Traversing
633 * Removes elements matching the specified expression from the set
634 * of matched elements. This method is used to remove one or more
635 * elements from a jQuery object.
637 * @example $("p").not("#selected")
638 * @before <p>Hello</p><p id="selected">Hello Again</p>
639 * @result [ <p>Hello</p> ]
643 * @param String expr An expression with which to remove matching elements
644 * @cat DOM/Traversing
647 return this.pushStack( t.constructor == String ?
648 jQuery.filter(t,this,false).r :
649 jQuery.grep(this,function(a){ return a != t; }), arguments );
653 * Adds the elements matched by the expression to the jQuery object. This
654 * can be used to concatenate the result sets of two expressions.
656 * @example $("p").add("span")
657 * @before <p>Hello</p><p><span>Hello Again</span></p>
658 * @result [ <p>Hello</p>, <span>Hello Again</span> ]
662 * @param String expr An expression whose matched elements are added
663 * @cat DOM/Traversing
667 * Adds each of the Elements in the array to the set of matched elements.
668 * This is used to add a set of Elements to a jQuery object.
670 * @example $("p").add([document.getElementById("a"), document.getElementById("b")])
671 * @before <p>Hello</p><p><span id="a">Hello Again</span><span id="b">And Again</span></p>
672 * @result [ <p>Hello</p>, <span id="a">Hello Again</span>, <span id="b">And Again</span> ]
676 * @param Array<Element> els An array of Elements to add
677 * @cat DOM/Traversing
681 * Adds a single Element to the set of matched elements. This is used to
682 * add a single Element to a jQuery object.
684 * @example $("p").add( document.getElementById("a") )
685 * @before <p>Hello</p><p><span id="a">Hello Again</span></p>

2542 * @before <p class="hello">Hello</p> how are <p>you?</p>
2543 * @result how are <p>you?</p>
2547 * @param String expr A jQuery expression to filter elements by.
2548 * @cat DOM/Manipulation
2550 remove: function(a){
2551 if ( !a || jQuery.filter( [this], a ).r )
2552 this.parentNode.removeChild( this );
2556 * Removes all child nodes from the set of matched elements.
2558 * @example $("p").empty()
2559 * @before <p>Hello, <span>Person</span> <a href="#">and person</a></p>
2560 * @result [ <p></p> ]
2564 * @cat DOM/Manipulation
2567 while ( this.firstChild )
2568 this.removeChild( this.firstChild );
2572 * Binds a particular event (like click) to a each of a set of match elements.
2574 * @example $("p").bind( "click", function() { alert("Hello"); } )
2575 * @before <p>Hello</p>
2576 * @result [ <p>Hello</p> ]
2578 * Cancel a default action and prevent it from bubbling by returning false
2579 * from your function.
2581 * @example $("form").bind( "submit", function() { return false; } )
2583 * Cancel a default action by using the preventDefault method.
2585 * @example $("form").bind( "submit", function() { e.preventDefault(); } )
2587 * Stop an event from bubbling by using the stopPropogation method.
2589 * @example $("form").bind( "submit", function() { e.stopPropogation(); } )
2593 * @param String type An event type
2594 * @param Function fn A function to bind to the event on each of the set of matched elements
2597 bind: function( type, fn ) {
2598 if ( fn.constructor == String )
2599 fn = new Function("e", ( !fn.indexOf(".") ? "$(this)" : "return " ) + fn);
2600 jQuery.event.add( this, type, fn );
2604 * The opposite of bind, removes a bound event from each of the matched
2605 * elements. You must pass the identical function that was used in the original
2608 * @example $("p").unbind( "click", function() { alert("Hello"); } )
2609 * @before <p onclick="alert('Hello');">Hello</p>
2610 * @result [ <p>Hello</p> ]
2614 * @param String type An event type
2615 * @param Function fn A function to unbind from the event on each of the set of matched elements
2620 * Removes all bound events of a particular type from each of the matched
2623 * @example $("p").unbind( "click" )
2624 * @before <p onclick="alert('Hello');">Hello</p>
2625 * @result [ <p>Hello</p> ]
2629 * @param String type An event type
2634 * Removes all bound events from each of the matched elements.
2636 * @example $("p").unbind()
2637 * @before <p onclick="alert('Hello');">Hello</p>
2638 * @result [ <p>Hello</p> ]
2644 unbind: function( type, fn ) {
2645 jQuery.event.remove( this, type, fn );
2649 * Trigger a type of event on every matched element.
2651 * @example $("p").trigger("click")
2652 * @before <p click="alert('hello')">Hello</p>
2653 * @result alert('hello')
2657 * @param String type An event type to trigger.
2660 trigger: function( type, data ) {
