85 * The current SVN version of jQuery.
95 * The number of elements currently matched.
97 * @example $("img").length;
98 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
107 * The number of elements currently matched.
109 * @example $("img").size();
110 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
121 * Access all matched elements. This serves as a backwards-compatible
122 * way of accessing all matched elements (other than the jQuery object
123 * itself, which is, in fact, an array of elements).
125 * @example $("img").get();
126 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
127 * @result [ <img src="test1.jpg"/> <img src="test2.jpg"/> ]
130 * @type Array<Element>
134 * Access a single matched element. <tt>num</tt> is used to access the
135 * <tt>num</tt>th element matched.
137 * @example $("img").get(1);
138 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
139 * @result [ <img src="test1.jpg"/> ]
143 * @param Number num Access the element in the <tt>num</tt>th position.
147 * Set the jQuery object to an array of elements.
149 * @example $("img").get([ document.body ]);
150 * @result $("img").get() == [ document.body ]
155 * @param Elements elems An array of elements
157 get: function( num ) {
158 // Watch for when an array (of elements) is passed in
159 if ( num && num.constructor == Array ) {
161 // Use a tricky hack to make the jQuery object
162 // look and feel like an array
164 [].push.apply( this, num );
168 return num == undefined ?
170 // Return a 'clean' array
171 jQuery.map( this, function(a){ return a } ) :
173 // Return just the object
178 * Execute a function within the context of every matched element.
179 * This means that every time the passed-in function is executed
180 * (which is once for every element matched) the 'this' keyword
181 * points to the specific element.
183 * Additionally, the function, when executed, is passed a single
184 * argument representing the position of the element in the matched
187 * @example $("img").each(function(){ this.src = "test.jpg"; });
188 * @before <img/> <img/>
189 * @result <img src="test.jpg"/> <img src="test.jpg"/>
193 * @param Function fn A function to execute
195 each: function( fn, args ) {
196 // Iterate through all of the matched elements
197 for ( var i = 0; i < this.length; i++ )
199 // Execute the function within the context of each element
200 fn.apply( this[i], args || [i] );
206 * Access a property on the first matched element.
207 * This method makes it easy to retreive a property value
208 * from the first matched element.
210 * @example $("img").attr("src");
211 * @before <img src="test.jpg"/>
216 * @param String name The name of the property to access.
220 * Set a hash of key/value object properties to all matched elements.
221 * This serves as the best way to set a large number of properties
222 * on all matched elements.
224 * @example $("img").attr({ src: "test.jpg", alt: "Test Image" });
226 * @result <img src="test.jpg" alt="Test Image"/>
230 * @param Hash prop A set of key/value pairs to set as object properties.
234 * Set a single property to a value, on all matched elements.
236 * @example $("img").attr("src","test.jpg");
238 * @result <img src="test.jpg"/>
242 * @param String key The name of the property to set.
243 * @param Object value The value to set the property to.
245 attr: function( key, value, type ) {
246 // Check to see if we're setting style values

250 if ( value == undefined )

261 type ? this.style : this,
266 // Look for the case where we're accessing a style value
267 jQuery[ type || "attr" ]( this[0], key );
271 * Access a style property on the first matched element.
272 * This method makes it easy to retreive a style property value
273 * from the first matched element.
275 * @example $("p").css("red");
276 * @before <p style="color:red;">Test Paragraph.</p>
281 * @param String name The name of the property to access.
285 * Set a hash of key/value style properties to all matched elements.
286 * This serves as the best way to set a large number of style properties
287 * on all matched elements.
289 * @example $("p").css({ color: "red", background: "blue" });
290 * @before <p>Test Paragraph.</p>
291 * @result <p style="color:red; background:blue;">Test Paragraph.</p>
295 * @param Hash prop A set of key/value pairs to set as style properties.
299 * Set a single style property to a value, on all matched elements.
301 * @example $("p").css("color","red");
302 * @before <p>Test Paragraph.</p>
303 * @result <p style="color:red;">Test Paragraph.</p>
307 * @param String key The name of the property to set.
308 * @param Object value The value to set the property to.
310 css: function( key, value ) {
311 return this.attr( key, value, "curCSS" );
315 * Retreive the text contents of all matched elements. The result is
316 * a string that contains the combined text contents of all matched
317 * elements. This method works on both HTML and XML documents.
319 * @example $("p").text();
320 * @before <p>Test Paragraph.</p>
321 * @result Test Paragraph.

332 t += r[i].nodeType != 1 ?
333 r[i].nodeValue : jQuery.fn.text([ r[i] ]);
339 * Wrap all matched elements with a structure of other elements.
340 * This wrapping process is most useful for injecting additional
341 * stucture into a document, without ruining the original semantic
342 * qualities of a document.
344 * The way that is works is that it goes through the first element argument
345 * provided and finds the deepest element within the structure - it is that
346 * element that will en-wrap everything else.
348 * @example $("p").wrap("<div class='wrap'></div>");
349 * @before <p>Test Paragraph.</p>
350 * @result <div class='wrap'><p>Test Paragraph.</p></div>
354 * @any String html A string of HTML, that will be created on the fly and wrapped around the target.
355 * @any Element elem A DOM element that will be wrapped.
356 * @any Array<Element> elems An array of elements, the first of which will be wrapped.
357 * @any Object obj Any object, converted to a string, then a text node.
360 // The elements to wrap the target around
361 var a = jQuery.clean(arguments);
363 // Wrap each of the matched elements individually
364 return this.each(function(){
365 // Clone the structure that we're using to wrap
366 var b = a[0].cloneNode(true);
368 // Insert it before the element to be wrapped
369 this.parentNode.insertBefore( b, this );
371 // Find he deepest point in the wrap structure
372 while ( b.firstChild )
375 // Move the matched element to within the wrap structure
376 b.appendChild( this );
381 * Append any number of elements to the inside of all matched elements.
382 * This operation is similar to doing an <tt>appendChild</tt> to all the
383 * specified elements, adding them into the document.
385 * @example $("p").append("<b>Hello</b>");
386 * @before <p>I would like to say: </p>
387 * @result <p>I would like to say: <b>Hello</b></p>
391 * @any String html A string of HTML, that will be created on the fly and appended to the target.
392 * @any Element elem A DOM element that will be appended.
393 * @any Array<Element> elems An array of elements, all of which will be appended.
394 * @any Object obj Any object, converted to a string, then a text node.
397 return this.domManip(arguments, true, 1, function(a){
398 this.appendChild( a );
403 * Prepend any number of elements to the inside of all matched elements.
404 * This operation is the best way to insert a set of elements inside, at the
405 * beginning, of all the matched element.
407 * @example $("p").prepend("<b>Hello</b>");
408 * @before <p>, how are you?</p>
409 * @result <p><b>Hello</b>, how are you?</p>
413 * @any String html A string of HTML, that will be created on the fly and prepended to the target.
414 * @any Element elem A DOM element that will be prepended.
415 * @any Array<Element> elems An array of elements, all of which will be prepended.
416 * @any Object obj Any object, converted to a string, then a text node.
418 prepend: function() {
419 return this.domManip(arguments, true, -1, function(a){
420 this.insertBefore( a, this.firstChild );
425 * Insert any number of elements before each of the matched elements.
427 * @example $("p").before("<b>Hello</b>");
428 * @before <p>how are you?</p>
429 * @result <b>Hello</b><p>how are you?</p>
433 * @any String html A string of HTML, that will be created on the fly and inserted.
434 * @any Element elem A DOM element that will beinserted.
435 * @any Array<Element> elems An array of elements, all of which will be inserted.
436 * @any Object obj Any object, converted to a string, then a text node.
439 return this.domManip(arguments, false, 1, function(a){
440 this.parentNode.insertBefore( a, this );
445 * Insert any number of elements after each of the matched elements.
447 * @example $("p").after("<p>I'm doing fine.</p>");
448 * @before <p>How are you?</p>
449 * @result <p>How are you?</p><p>I'm doing fine.</p>
453 * @any String html A string of HTML, that will be created on the fly and inserted.
454 * @any Element elem A DOM element that will beinserted.
455 * @any Array<Element> elems An array of elements, all of which will be inserted.
456 * @any Object obj Any object, converted to a string, then a text node.
459 return this.domManip(arguments, false, -1, function(a){
460 this.parentNode.insertBefore( a, this.nextSibling );
465 * End the most recent 'destructive' operation, reverting the list of matched elements
466 * back to its previous state. After an end operation, the list of matched elements will
467 * revert to the last state of matched elements.
469 * @example $("p").find("span").end();
470 * @before <p><span>Hello</span>, how are you?</p>
471 * @result $("p").find("span").end() == [ <p>...</p> ]
477 return this.get( this.stack.pop() );
481 * Searches for all elements that match the specified expression.
482 * This method is the optimal way of finding additional descendant
483 * elements with which to process.
485 * All searching is done using a jQuery expression. The expression can be
486 * written using CSS 1-3 Selector syntax, or basic XPath.
488 * @example $("p").find("span");
489 * @before <p><span>Hello</span>, how are you?</p>
490 * @result $("p").find("span") == [ <span>Hello</span> ]
494 * @param String expr An expression to search with.
497 return this.pushStack( jQuery.map( this, function(a){
498 return jQuery.find(t,a);
503 * Removes all elements from the set of matched elements that do not
504 * match the specified expression. This method is used to narrow down
505 * the results of a search.
507 * All searching is done using a jQuery expression. The expression
508 * can be written using CSS 1-3 Selector syntax, or basic XPath.
510 * @example $("p").filter(".selected")
511 * @before <p class="selected">Hello</p><p>How are you?</p>
512 * @result $("p").filter(".selected") == [ <p class="selected">Hello</p> ]
516 * @param String expr An expression to search with.
520 * Removes all elements from the set of matched elements that do not
521 * match at least one of the expressions passed to the function. This
522 * method is used when you want to filter the set of matched elements
523 * through more than one expression.
525 * Elements will be retained in the jQuery object if they match at
526 * least one of the expressions passed.
528 * @example $("p").filter([".selected", ":first"])
529 * @before <p>Hello</p><p>Hello Again</p><p class="selected">And Again</p>
530 * @result $("p").filter([".selected", ":first"]) == [ <p>Hello</p>, <p class="selected">And Again</p> ]
534 * @param Array<String> exprs A set of expressions to evaluate against
536 filter: function(t) {
537 return this.pushStack(
538 t.constructor == Array &&

546 ( t ? this.get() : [] ) ||
548 t.constructor == Function &&
549 jQuery.grep( this, t ) ||
551 jQuery.filter(t,this).r, arguments );
555 * Removes the specified Element from the set of matched elements. This
556 * method is used to remove a single Element from a jQuery object.
558 * @example $("p").not( document.getElementById("selected") )
559 * @before <p>Hello</p><p id="selected">Hello Again</p>
560 * @result [ <p>Hello</p> ]
564 * @param Element el An element to remove from the set
568 * Removes elements matching the specified expression from the set
569 * of matched elements. This method is used to remove one or more
570 * elements from a jQuery object.
572 * @example $("p").not("#selected")
573 * @before <p>Hello</p><p id="selected">Hello Again</p>
574 * @result [ <p>Hello</p> ]
578 * @param String expr An expression with which to remove matching elements
581 return this.pushStack( t.constructor == String ?
582 jQuery.filter(t,this,false).r :
583 jQuery.grep(this,function(a){ return a != t; }), arguments );
587 * Adds the elements matched by the expression to the jQuery object. This
588 * can be used to concatenate the result sets of two expressions.
590 * @example $("p").add("span")
591 * @before <p>Hello</p><p><span>Hello Again</span></p>
592 * @result [ <p>Hello</p>, <span>Hello Again</span> ]
596 * @param String expr An expression whose matched elements are added
600 * Adds each of the Elements in the array to the set of matched elements.
601 * This is used to add a set of Elements to a jQuery object.
603 * @example $("p").add([document.getElementById("a"), document.getElementById("b")])
604 * @before <p>Hello</p><p><span id="a">Hello Again</span><span id="b">And Again</span></p>
605 * @result [ <p>Hello</p>, <span id="a">Hello Again</span>, <span id="b">And Again</span> ]
609 * @param Array<Element> els An array of Elements to add
613 * Adds a single Element to the set of matched elements. This is used to
614 * add a single Element to a jQuery object.
616 * @example $("p").add( document.getElementById("a") )
617 * @before <p>Hello</p><p><span id="a">Hello Again</span></p>
618 * @result [ <p>Hello</p>, <span id="a">Hello Again</span> ]
622 * @param Element el An Element to add
625 return this.pushStack( jQuery.merge( this, t.constructor == String ?
