70 * This function accepts a string containing a CSS or
71 * basic XPath selector which is then used to match a set of elements.
73 * The core functionality of jQuery centers around this function.
74 * Everything in jQuery is based upon this, or uses this in some way.
75 * The most basic use of this function is to pass in an expression
76 * (usually consisting of CSS or XPath), which then finds all matching
79 * By default, if no context is specified, $() looks for DOM elements within the context of the
80 * current HTML document. If you do specify a context, such as a DOM
81 * element or jQuery object, the expression will be matched against
82 * the contents of that context.
84 * See [[DOM/Traversing/Selectors]] for the allowed CSS/XPath syntax for expressions.
86 * @example $("div > p")
87 * @desc Finds all p elements that are children of a div element.
88 * @before <p>one</p> <div><p>two</p></div> <p>three</p>
89 * @result [ <p>two</p> ]
91 * @example $("input:radio", document.forms[0])
92 * @desc Searches for all inputs of type radio within the first form in the document
94 * @example $("div", xml.responseXML)
95 * @desc This finds all div elements within the specified XML document.
98 * @param String expr An expression to search with
99 * @param Element|jQuery context (optional) A DOM Element, Document or jQuery to use as context
103 * @see $(Element<Array>)
107 * Create DOM elements on-the-fly from the provided String of raw HTML.
109 * @example $("<div><p>Hello</p></div>").appendTo("body")
110 * @desc Creates a div element (and all of its contents) dynamically,
111 * and appends it to the body element. Internally, an
112 * element is created and its innerHTML property set to the given markup.
113 * It is therefore both quite flexible and limited.
116 * @param String html A string of HTML to create on the fly.
119 * @see appendTo(String)
123 * Wrap jQuery functionality around a single or multiple DOM Element(s).
125 * This function also accepts XML Documents and Window objects
126 * as valid arguments (even though they are not DOM Elements).
128 * @example $(document.body).css( "background", "black" );
129 * @desc Sets the background color of the page to black.
131 * @example $( myForm.elements ).hide()
132 * @desc Hides all the input elements within a form
135 * @param Element|Array<Element> elems DOM element(s) to be encapsulated by a jQuery object.
141 * A shorthand for $(document).ready(), allowing you to bind a function
142 * to be executed when the DOM document has finished loading. This function
143 * behaves just like $(document).ready(), in that it should be used to wrap
144 * other $() operations on your page that depend on the DOM being ready to be
145 * operated on. While this function is, technically, chainable - there really
146 * isn't much use for chaining against it.
148 * You can have as many $(document).ready events on your page as you like.
150 * See ready(Function) for details about the ready event.
152 * @example $(function(){
153 * // Document is ready
155 * @desc Executes the function when the DOM is ready to be used.
157 * @example jQuery(function($) {
158 * // Your code using failsafe $ alias here...
160 * @desc Uses both the shortcut for $(document).ready() and the argument
161 * to write failsafe jQuery code using the $ alias, without relying on the
165 * @param Function fn The function to execute when the DOM is ready.
168 * @see ready(Function)
171 jQuery.fn = jQuery.prototype = {
173 * The current version of jQuery.
184 * The number of elements currently matched. The size function will return the same value.
186 * @example $("img").length;
187 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
197 * Get the number of elements currently matched. This returns the same
198 * number as the 'length' property of the jQuery object.
200 * @example $("img").size();
201 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
215 * Access all matched DOM elements. This serves as a backwards-compatible
216 * way of accessing all matched elements (other than the jQuery object
217 * itself, which is, in fact, an array of elements).
219 * It is useful if you need to operate on the DOM elements themselves instead of using built-in jQuery functions.
221 * @example $("img").get();
222 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
223 * @result [ <img src="test1.jpg"/> <img src="test2.jpg"/> ]
224 * @desc Selects all images in the document and returns the DOM Elements as an Array
227 * @type Array<Element>
232 * Access a single matched DOM element at a specified index in the matched set.
233 * This allows you to extract the actual DOM element and operate on it
234 * directly without necessarily using jQuery functionality on it.
236 * @example $("img").get(0);
237 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
238 * @result <img src="test1.jpg"/>
239 * @desc Selects all images in the document and returns the first one
243 * @param Number num Access the element in the Nth position.
246 get: function( num ) {
247 return num == undefined ?
249 // Return a 'clean' array
250 jQuery.makeArray( this ) :
252 // Return just the object
257 * Set the jQuery object to an array of elements, while maintaining
260 * @example $("img").pushStack([ document.body ]);
261 * @result $("img").pushStack() == [ document.body ]
266 * @param Elements elems An array of elements
269 pushStack: function( a ) {
271 ret.prevObject = this;
276 * Set the jQuery object to an array of elements. This operation is
277 * completely destructive - be sure to use .pushStack() if you wish to maintain
280 * @example $("img").setArray([ document.body ]);
281 * @result $("img").setArray() == [ document.body ]
286 * @param Elements elems An array of elements
289 setArray: function( a ) {
291 [].push.apply( this, a );
296 * Execute a function within the context of every matched element.
297 * This means that every time the passed-in function is executed
298 * (which is once for every element matched) the 'this' keyword
299 * points to the specific DOM element.
301 * Additionally, the function, when executed, is passed a single
302 * argument representing the position of the element in the matched
303 * set (integer, zero-index).
305 * @example $("img").each(function(i){
306 * this.src = "test" + i + ".jpg";
308 * @before <img/><img/>
309 * @result <img src="test0.jpg"/><img src="test1.jpg"/>
310 * @desc Iterates over two images and sets their src property
314 * @param Function fn A function to execute
317 each: function( fn, args ) {
318 return jQuery.each( this, fn, args );
322 * Searches every matched element for the object and returns
323 * the index of the element, if found, starting with zero.
324 * Returns -1 if the object wasn't found.
326 * @example $("*").index( $('#foobar')[0] )
327 * @before <div id="foobar"><b></b><span id="foo"></span></div>
329 * @desc Returns the index for the element with ID foobar
331 * @example $("*").index( $('#foo')[0] )
332 * @before <div id="foobar"><b></b><span id="foo"></span></div>
334 * @desc Returns the index for the element with ID foo within another element
336 * @example $("*").index( $('#bar')[0] )
337 * @before <div id="foobar"><b></b><span id="foo"></span></div>
339 * @desc Returns -1, as there is no element with ID bar
343 * @param Element subject Object to search for
346 index: function( obj ) {
348 this.each(function(i){
349 if ( this == obj ) pos = i;
355 * Access a property on the first matched element.
356 * This method makes it easy to retrieve a property value
357 * from the first matched element.
359 * @example $("img").attr("src");
360 * @before <img src="test.jpg"/>
362 * @desc Returns the src attribute from the first image in the document.
366 * @param String name The name of the property to access.
367 * @cat DOM/Attributes
371 * Set a key/value object as properties to all matched elements.
373 * This serves as the best way to set a large number of properties
374 * on all matched elements.
376 * @example $("img").attr({ src: "test.jpg", alt: "Test Image" });
378 * @result <img src="test.jpg" alt="Test Image"/>
379 * @desc Sets src and alt attributes to all images.
383 * @param Map properties Key/value pairs to set as object properties.
384 * @cat DOM/Attributes
388 * Set a single property to a value, on all matched elements.
390 * Can compute values provided as ${formula}, see second example.
392 * Note that you can't set the name property of input elements in IE.
393 * Use $(html) or .append(html) or .html(html) to create elements
394 * on the fly including the name property.
396 * @example $("img").attr("src","test.jpg");
398 * @result <img src="test.jpg"/>
399 * @desc Sets src attribute to all images.
401 * @example $("img").attr("title", "${this.src}");
402 * @before <img src="test.jpg" />
403 * @result <img src="test.jpg" title="test.jpg" />
404 * @desc Sets title attribute from src attribute, a shortcut for attr(String,Function)
408 * @param String key The name of the property to set.
409 * @param Object value The value to set the property to.
410 * @cat DOM/Attributes
414 * Set a single property to a computed value, on all matched elements.
416 * Instead of a value, a function is provided, that computes the value.
418 * @example $("img").attr("title", function() { return this.src });
419 * @before <img src="test.jpg" />
420 * @result <img src="test.jpg" title="test.jpg" />
421 * @desc Sets title attribute from src attribute.
423 * @example $("img").attr("title", function(index) { return this.title + (i + 1); });
424 * @before <img title="pic" /><img title="pic" /><img title="pic" />
425 * @result <img title="pic1" /><img title="pic2" /><img title="pic3" />
426 * @desc Enumerate title attribute.
430 * @param String key The name of the property to set.
431 * @param Function value A function returning the value to set.
432 * Scope: Current element, argument: Index of current element
433 * @cat DOM/Attributes

469 * @before <p style="font-weight: bold;">Test Paragraph.</p>
471 * @desc Retrieves the font-weight style of the first paragraph.
475 * @param String name The name of the property to access.
480 * Set a key/value object as style properties to all matched elements.
482 * This serves as the best way to set a large number of style properties
483 * on all matched elements.
485 * @example $("p").css({ color: "red", background: "blue" });
486 * @before <p>Test Paragraph.</p>
487 * @result <p style="color:red; background:blue;">Test Paragraph.</p>
488 * @desc Sets color and background styles to all p elements.
492 * @param Map properties Key/value pairs to set as style properties.
497 * Set a single style property to a value, on all matched elements.
498 * If a number is provided, it is automatically converted into a pixel value.
500 * @example $("p").css("color","red");
501 * @before <p>Test Paragraph.</p>
502 * @result <p style="color:red;">Test Paragraph.</p>
503 * @desc Changes the color of all paragraphs to red

513 * @param String|Number value The value to set the property to.
516 css: function( key, value ) {
517 return this.attr( key, value, "curCSS" );
521 * Get the text contents of all matched elements. The result is
522 * a string that contains the combined text contents of all matched
523 * elements. This method works on both HTML and XML documents.
525 * @example $("p").text();
526 * @before <p><b>Test</b> Paragraph.</p><p>Paraparagraph</p>
527 * @result Test Paragraph.Paraparagraph
528 * @desc Gets the concatenated text of all paragraphs
532 * @cat DOM/Attributes
536 * Set the text contents of all matched elements.
538 * Similar to html(), but escapes HTML (replace "<" and ">" with their

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