71 * This function accepts a string containing a CSS or
72 * basic XPath selector which is then used to match a set of elements.
74 * The core functionality of jQuery centers around this function.
75 * Everything in jQuery is based upon this, or uses this in some way.
76 * The most basic use of this function is to pass in an expression
77 * (usually consisting of CSS or XPath), which then finds all matching
80 * By default, $() looks for DOM elements within the context of the
81 * current HTML document.
83 * @example $("div > p")
84 * @desc Finds all p elements that are children of a div element.
85 * @before <p>one</p> <div><p>two</p></div> <p>three</p>
86 * @result [ <p>two</p> ]
88 * @example $("input:radio", document.forms[0])
89 * @desc Searches for all inputs of type radio within the first form in the document
91 * @example $("div", xml.responseXML)
92 * @desc This finds all div elements within the specified XML document.
95 * @param String expr An expression to search with
96 * @param Element|jQuery context (optional) A DOM Element, Document or jQuery to use as context
100 * @see $(Element<Array>)
104 * Create DOM elements on-the-fly from the provided String of raw HTML.
106 * @example $("<div><p>Hello</p></div>").appendTo("#body")
107 * @desc Creates a div element (and all of its contents) dynamically,
108 * and appends it to the element with the ID of body. Internally, an
109 * element is created and it's innerHTML property set to the given markup.
110 * It is therefore both quite flexible and limited.
113 * @param String html A string of HTML to create on the fly.
116 * @see appendTo(String)
120 * Wrap jQuery functionality around a single or multiple DOM Element(s).
122 * This function also accepts XML Documents and Window objects
123 * as valid arguments (even though they are not DOM Elements).
125 * @example $(document.body).background( "black" );
126 * @desc Sets the background color of the page to black.
128 * @example $( myForm.elements ).hide()
129 * @desc Hides all the input elements within a form
132 * @param Element|Array<Element> elems DOM element(s) to be encapsulated by a jQuery object.
138 * A shorthand for $(document).ready(), allowing you to bind a function
139 * to be executed when the DOM document has finished loading. This function
140 * behaves just like $(document).ready(), in that it should be used to wrap
141 * all of the other $() operations on your page. While this function is,
142 * technically, chainable - there really isn't much use for chaining against it.
143 * You can have as many $(document).ready events on your page as you like.
145 * See ready(Function) for details about the ready event.
147 * @example $(function(){
148 * // Document is ready
150 * @desc Executes the function when the DOM is ready to be used.
152 * @example jQuery(function($) {
153 * // Your code using failsafe $ alias here...
155 * @desc Uses both the shortcut for $(document).ready() and the argument
156 * to write failsafe jQuery code using the $ alias, without relying on the
160 * @param Function fn The function to execute when the DOM is ready.
163 * @see ready(Function)
166 jQuery.fn = jQuery.prototype = {
168 * The current version of jQuery.
179 * The number of elements currently matched.
181 * @example $("img").length;
182 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
192 * The number of elements currently matched.
194 * @example $("img").size();
195 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
209 * Access all matched elements. This serves as a backwards-compatible
210 * way of accessing all matched elements (other than the jQuery object
211 * itself, which is, in fact, an array of elements).
213 * @example $("img").get();
214 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
215 * @result [ <img src="test1.jpg"/> <img src="test2.jpg"/> ]
216 * @desc Selects all images in the document and returns the DOM Elements as an Array
219 * @type Array<Element>
224 * Access a single matched element. num is used to access the
225 * Nth element matched.
227 * @example $("img").get(0);
228 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
229 * @result [ <img src="test1.jpg"/> ]
230 * @desc Selects all images in the document and returns the first one
234 * @param Number num Access the element in the Nth position.
237 get: function( num ) {
238 return num == undefined ?
240 // Return a 'clean' array
241 jQuery.makeArray( this ) :
243 // Return just the object
248 * Set the jQuery object to an array of elements, while maintaining
251 * @example $("img").pushStack([ document.body ]);
252 * @result $("img").pushStack() == [ document.body ]
257 * @param Elements elems An array of elements
260 pushStack: function( a ) {
261 var ret = jQuery(this);
262 ret.prevObject = this;
263 return ret.setArray( a );
267 * Set the jQuery object to an array of elements. This operation is
268 * completely destructive - be sure to use .pushStack() if you wish to maintain
271 * @example $("img").setArray([ document.body ]);
272 * @result $("img").setArray() == [ document.body ]
277 * @param Elements elems An array of elements
280 setArray: function( a ) {
282 [].push.apply( this, a );
287 * Execute a function within the context of every matched element.
288 * This means that every time the passed-in function is executed
289 * (which is once for every element matched) the 'this' keyword
290 * points to the specific element.
292 * Additionally, the function, when executed, is passed a single
293 * argument representing the position of the element in the matched
296 * @example $("img").each(function(i){
297 * this.src = "test" + i + ".jpg";
299 * @before <img/><img/>
300 * @result <img src="test0.jpg"/><img src="test1.jpg"/>
301 * @desc Iterates over two images and sets their src property
305 * @param Function fn A function to execute
308 each: function( fn, args ) {
309 return jQuery.each( this, fn, args );
313 * Searches every matched element for the object and returns
314 * the index of the element, if found, starting with zero.
315 * Returns -1 if the object wasn't found.
317 * @example $("*").index( $('#foobar')[0] )
318 * @before <div id="foobar"><b></b><span id="foo"></span></div>
320 * @desc Returns the index for the element with ID foobar
322 * @example $("*").index( $('#foo')[0] )
323 * @before <div id="foobar"><b></b><span id="foo"></span></div>
325 * @desc Returns the index for the element with ID foo within another element
327 * @example $("*").index( $('#bar')[0] )
328 * @before <div id="foobar"><b></b><span id="foo"></span></div>
330 * @desc Returns -1, as there is no element with ID bar
334 * @param Element subject Object to search for
337 index: function( obj ) {
339 this.each(function(i){
340 if ( this == obj ) pos = i;
346 * Access a property on the first matched element.
347 * This method makes it easy to retrieve a property value
348 * from the first matched element.
350 * @example $("img").attr("src");
351 * @before <img src="test.jpg"/>
353 * @desc Returns the src attribute from the first image in the document.
357 * @param String name The name of the property to access.
358 * @cat DOM/Attributes
362 * Set a key/value object as properties to all matched elements.
364 * This serves as the best way to set a large number of properties
365 * on all matched elements.
367 * @example $("img").attr({ src: "test.jpg", alt: "Test Image" });
369 * @result <img src="test.jpg" alt="Test Image"/>
370 * @desc Sets src and alt attributes to all images.
374 * @param Map properties Key/value pairs to set as object properties.
375 * @cat DOM/Attributes
379 * Set a single property to a value, on all matched elements.
381 * Can compute values provided as ${formula}, see second example.
383 * Note that you can't set the name property of input elements in IE.
384 * Use $(html) or .append(html) or .html(html) to create elements
385 * on the fly including the name property.
387 * @example $("img").attr("src","test.jpg");
389 * @result <img src="test.jpg"/>
390 * @desc Sets src attribute to all images.
392 * @example $("img").attr("title", "${this.src}");
393 * @before <img src="test.jpg" />
394 * @result <img src="test.jpg" title="test.jpg" />
395 * @desc Sets title attribute from src attribute, a shortcut for attr(String,Function)
399 * @param String key The name of the property to set.
400 * @param Object value The value to set the property to.
401 * @cat DOM/Attributes
405 * Set a single property to a computed value, on all matched elements.
407 * Instead of a value, a function is provided, that computes the value.
409 * @example $("img").attr("title", function() { return this.src });
410 * @before <img src="test.jpg" />
411 * @result <img src="test.jpg" title="test.jpg" />
412 * @desc Sets title attribute from src attribute.

415 * @before <img title="pic" /><img title="pic" /><img title="pic" />
416 * @result <img title="pic1" /><img title="pic2" /><img title="pic3" />
417 * @desc Enumerate title attribute.
421 * @param String key The name of the property to set.
422 * @param Function value A function returning the value to set.
423 * Scope: Current element, argument: Index of current element

466 * @param String name The name of the property to access.
471 * Set a key/value object as style properties to all matched elements.
473 * This serves as the best way to set a large number of style properties
474 * on all matched elements.
476 * @example $("p").css({ color: "red", background: "blue" });
477 * @before <p>Test Paragraph.</p>
478 * @result <p style="color:red; background:blue;">Test Paragraph.</p>
479 * @desc Sets color and background styles to all p elements.
483 * @param Map properties Key/value pairs to set as style properties.
488 * Set a single style property to a value, on all matched elements.
489 * If a number is provided, it is automatically converted into a pixel value.
491 * @example $("p").css("color","red");
492 * @before <p>Test Paragraph.</p>
493 * @result <p style="color:red;">Test Paragraph.</p>
494 * @desc Changes the color of all paragraphs to red

504 * @param String|Number value The value to set the property to.
507 css: function( key, value ) {
508 return this.attr( key, value, "curCSS" );
512 * Get the text contents of all matched elements. The result is
513 * a string that contains the combined text contents of all matched
514 * elements. This method works on both HTML and XML documents.
516 * @example $("p").text();
517 * @before <p><b>Test</b> Paragraph.</p><p>Paraparagraph</p>
518 * @result Test Paragraph.Paraparagraph
519 * @desc Gets the concatenated text of all paragraphs

563 * Wrap all matched elements with a structure of other elements.
564 * This wrapping process is most useful for injecting additional
565 * stucture into a document, without ruining the original semantic
566 * qualities of a document.
568 * This works by going through the first element
569 * provided (which is generated, on the fly, from the provided HTML)
570 * and finds the deepest ancestor element within its
571 * structure - it is that element that will en-wrap everything else.
573 * This does not work with elements that contain text. Any necessary text
574 * must be added after the wrapping is done.
