81 * This function accepts a string containing a CSS selector,
82 * basic XPath, or raw HTML, which is then used to match a set of elements.
83 * The HTML string is different from the traditional selectors in that
84 * it creates the DOM elements representing that HTML string, on the fly,
85 * to be (assumedly) inserted into the document later.
87 * The core functionality of jQuery centers around this function.
88 * Everything in jQuery is based upon this, or uses this in some way.
89 * The most basic use of this function is to pass in an expression
90 * (usually consisting of CSS or XPath), which then finds all matching
91 * elements and remembers them for later use.
93 * By default, $() looks for DOM elements within the context of the
94 * current HTML document.
96 * @example $("div > p")
97 * @desc This finds all p elements that are children of a div element.
98 * @before <p>one</p> <div><p>two</p></div> <p>three</p>
99 * @result [ <p>two</p> ]
101 * @example $("<div><p>Hello</p></div>").appendTo("#body")
102 * @desc Creates a div element (and all of its contents) dynamically,
103 * and appends it to the element with the ID of body. Internally, an
104 * element is created and it's innerHTML property set to the given markup.
105 * It is therefore both quite flexible and limited.
108 * @param String expr An expression to search with, or a string of HTML to create on the fly.
114 * This function accepts a string containing a CSS selector, or
115 * basic XPath, which is then used to match a set of elements with the
116 * context of the specified DOM element, or document
118 * @example $("div", xml.responseXML)
119 * @desc This finds all div elements within the specified XML document.
122 * @param String expr An expression to search with.
123 * @param Element context A DOM Element, or Document, representing the base context.
129 * Wrap jQuery functionality around a specific DOM Element.
130 * This function also accepts XML Documents and Window objects
131 * as valid arguments (even though they are not DOM Elements).
133 * @example $(document).find("div > p")
134 * @before <p>one</p> <div><p>two</p></div> <p>three</p>
135 * @result [ <p>two</p> ]
137 * @example $(document.body).background( "black" );
138 * @desc Sets the background color of the page to black.
141 * @param Element elem A DOM element to be encapsulated by a jQuery object.
147 * Wrap jQuery functionality around a set of DOM Elements.
149 * @example $( myForm.elements ).hide()
150 * @desc Hides all the input elements within a form
153 * @param Array<Element> elems An array of DOM elements to be encapsulated by a jQuery object.
159 * A shorthand for $(document).ready(), allowing you to bind a function
160 * to be executed when the DOM document has finished loading. This function
161 * behaves just like $(document).ready(), in that it should be used to wrap
162 * all of the other $() operations on your page. While this function is,
163 * technically, chainable - there really isn't much use for chaining against it.
164 * You can have as many $(document).ready events on your page as you like.
166 * @example $(function(){
167 * // Document is ready
169 * @desc Executes the function when the DOM is ready to be used.
172 * @param Function fn The function to execute when the DOM is ready.
178 * A means of creating a cloned copy of a jQuery object. This function
179 * copies the set of matched elements from one jQuery object and creates
180 * another, new, jQuery object containing the same elements.
182 * @example var div = $("div");
183 * $( div ).find("p");
184 * @desc Locates all p elements with all div elements, without disrupting the original jQuery object contained in 'div' (as would normally be the case if a simple div.find("p") was done).
187 * @param jQuery obj The jQuery object to be cloned.
192 // Map the jQuery namespace to the '$' one
195 jQuery.fn = jQuery.prototype = {
197 * The current version of jQuery.
208 * The number of elements currently matched.
210 * @example $("img").length;
211 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
214 * @test ok( $("div").length == 2, "Get Number of Elements Found" );
223 * The number of elements currently matched.
225 * @example $("img").size();
226 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
229 * @test ok( $("div").size() == 2, "Get Number of Elements Found" );
240 * Access all matched elements. This serves as a backwards-compatible
241 * way of accessing all matched elements (other than the jQuery object
242 * itself, which is, in fact, an array of elements).
244 * @example $("img").get();
245 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
246 * @result [ <img src="test1.jpg"/> <img src="test2.jpg"/> ]
248 * @test isSet( $("div").get(), q("main","foo"), "Get All Elements" );
251 * @type Array<Element>
256 * Access a single matched element. num is used to access the
257 * Nth element matched.
259 * @example $("img").get(1);
260 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
261 * @result [ <img src="test1.jpg"/> ]
263 * @test ok( $("div").get(0) == document.getElementById("main"), "Get A Single Element" );
267 * @param Number num Access the element in the Nth position.
272 * Set the jQuery object to an array of elements.
274 * @example $("img").get([ document.body ]);
275 * @result $("img").get() == [ document.body ]
280 * @param Elements elems An array of elements
283 get: function( num ) {
284 // Watch for when an array (of elements) is passed in
285 if ( num && num.constructor == Array ) {
287 // Use a tricky hack to make the jQuery object
288 // look and feel like an array
290 [].push.apply( this, num );
294 return num == undefined ?
296 // Return a 'clean' array
297 jQuery.merge( this, [] ) :
299 // Return just the object
304 * Execute a function within the context of every matched element.
305 * This means that every time the passed-in function is executed
306 * (which is once for every element matched) the 'this' keyword
307 * points to the specific element.
309 * Additionally, the function, when executed, is passed a single
310 * argument representing the position of the element in the matched
313 * @example $("img").each(function(){
314 * this.src = "test.jpg";
316 * @before <img/> <img/>
317 * @result <img src="test.jpg"/> <img src="test.jpg"/>
319 * @example $("img").each(function(i){
320 * alert( "Image #" + i + " is " + this );
322 * @before <img/> <img/>
323 * @result <img src="test.jpg"/> <img src="test.jpg"/>
325 * @test var div = $("div");
326 * div.each(function(){this.foo = 'zoo';});
328 * for ( var i = 0; i < div.size(); i++ ) {
329 * if ( div.get(i).foo != "zoo" ) pass = false;
331 * ok( pass, "Execute a function, Relative" );
335 * @param Function fn A function to execute
338 each: function( fn, args ) {
339 return jQuery.each( this, fn, args );
343 * Searches every matched element for the object and returns
344 * the index of the element, if found, starting with zero.
345 * Returns -1 if the object wasn't found.
347 * @example $("*").index(document.getElementById('foobar'))
348 * @before <div id="foobar"></div><b></b><span id="foo"></span>
351 * @example $("*").index(document.getElementById('foo'))
352 * @before <div id="foobar"></div><b></b><span id="foo"></span>
355 * @example $("*").index(document.getElementById('bar'))
356 * @before <div id="foobar"></div><b></b><span id="foo"></span>
359 * @test ok( $([window, document]).index(window) == 0, "Check for index of elements" );
360 * ok( $([window, document]).index(document) == 1, "Check for index of elements" );

383 * Access a property on the first matched element.

3407 * The opposite of bind, removes a bound event from each of the matched
3408 * elements. You must pass the identical function that was used in the original
3411 * @example $("p").unbind( "click", function() { alert("Hello"); } )

3417 * @param String type An event type
3418 * @param Function fn A function to unbind from the event on each of the set of matched elements
