\r
77 * This function accepts a string containing a CSS selector,
\r
78 * basic XPath, or raw HTML, which is then used to match a set of elements.
\r
79 * The HTML string is different from the traditional selectors in that
\r
80 * it creates the DOM elements representing that HTML string, on the fly,
\r
81 * to be (assumedly) inserted into the document later.
\r
83 * The core functionality of jQuery centers around this function.
\r
84 * Everything in jQuery is based upon this, or uses this in some way.
\r
85 * The most basic use of this function is to pass in an expression
\r
86 * (usually consisting of CSS or XPath), which then finds all matching
\r
87 * elements and remembers them for later use.
\r
89 * By default, $() looks for DOM elements within the context of the
\r
90 * current HTML document.
\r
92 * @example $("div > p")
\r
93 * @desc This finds all p elements that are children of a div element.
\r
94 * @before <p>one</p> <div><p>two</p></div> <p>three</p>
\r
95 * @result [ <p>two</p> ]
\r
97 * @example $("<div><p>Hello</p></div>").appendTo("#body")
\r
98 * @desc Creates a div element (and all of its contents) dynamically,
\r
99 * and appends it to the element with the ID of body. Internally, an
\r
100 * element is created and it's innerHTML property set to the given markup.
\r
101 * It is therefore both quite flexible and limited.
\r
104 * @param String expr An expression to search with, or a string of HTML to create on the fly.
\r
110 * This function accepts a string containing a CSS selector, or
\r
111 * basic XPath, which is then used to match a set of elements with the
\r
112 * context of the specified DOM element, or document
\r
114 * @example $("div", xml.responseXML)
\r
115 * @desc This finds all div elements within the specified XML document.
\r
118 * @param String expr An expression to search with.
\r
119 * @param Element context A DOM Element, or Document, representing the base context.
\r
125 * Wrap jQuery functionality around a specific DOM Element.
\r
126 * This function also accepts XML Documents and Window objects
\r
127 * as valid arguments (even though they are not DOM Elements).
\r
129 * @example $(document).find("div > p")
\r
130 * @before <p>one</p> <div><p>two</p></div> <p>three</p>
\r
131 * @result [ <p>two</p> ]
\r
133 * @example $(document.body).background( "black" );
\r
134 * @desc Sets the background color of the page to black.
\r
137 * @param Element elem A DOM element to be encapsulated by a jQuery object.
\r
143 * Wrap jQuery functionality around a set of DOM Elements.
\r
145 * @example $( myForm.elements ).hide()
\r
146 * @desc Hides all the input elements within a form
\r
149 * @param Array<Element> elems An array of DOM elements to be encapsulated by a jQuery object.
\r
155 * A shorthand for $(document).ready(), allowing you to bind a function
\r
156 * to be executed when the DOM document has finished loading. This function
\r
157 * behaves just like $(document).ready(), in that it should be used to wrap
\r
158 * all of the other $() operations on your page. While this function is,
\r
159 * technically, chainable - there really isn't much use for chaining against it.
\r
160 * You can have as many $(document).ready events on your page as you like.
\r
162 * @example $(function(){
\r
163 * // Document is ready
\r
165 * @desc Executes the function when the DOM is ready to be used.
\r
168 * @param Function fn The function to execute when the DOM is ready.
\r
174 * A means of creating a cloned copy of a jQuery object. This function
\r
175 * copies the set of matched elements from one jQuery object and creates
\r
176 * another, new, jQuery object containing the same elements.
\r
178 * @example var div = $("div");
\r
179 * $( div ).find("p");
\r
180 * @desc Locates all p elements with all div elements, without disrupting the original jQuery object contained in 'div' (as would normally be the case if a simple div.find("p") was done).
\r
183 * @param jQuery obj The jQuery object to be cloned.
\r
188 // Map the jQuery namespace to the '$' one
\r
191 jQuery.fn = jQuery.prototype = {
\r
193 * The current version of jQuery.
\r
201 jquery: "@VERSION",
\r
204 * The number of elements currently matched.
\r
206 * @example $("img").length;
\r
207 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
\r
210 * @test ok( $("div").length == 2, "Get Number of Elements Found" );
\r
219 * The number of elements currently matched.
\r
221 * @example $("img").size();
\r
222 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
\r
225 * @test ok( $("div").size() == 2, "Get Number of Elements Found" );
\r
232 return this.length;
\r
236 * Access all matched elements. This serves as a backwards-compatible
\r
237 * way of accessing all matched elements (other than the jQuery object
\r
238 * itself, which is, in fact, an array of elements).
\r
240 * @example $("img").get();
\r
241 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
\r
242 * @result [ <img src="test1.jpg"/> <img src="test2.jpg"/> ]
\r
244 * @test isSet( $("div").get(), q("main","foo"), "Get All Elements" );
\r
247 * @type Array<Element>
\r
252 * Access a single matched element. num is used to access the
\r
253 * Nth element matched.
\r
255 * @example $("img").get(1);
\r
256 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
\r
257 * @result [ <img src="test1.jpg"/> ]
\r
259 * @test ok( $("div").get(0) == document.getElementById("main"), "Get A Single Element" );
\r
263 * @param Number num Access the element in the Nth position.
\r
268 * Set the jQuery object to an array of elements.
\r
270 * @example $("img").get([ document.body ]);
\r
271 * @result $("img").get() == [ document.body ]
\r
276 * @param Elements elems An array of elements
\r
279 get: function( num ) {
\r
280 // Watch for when an array (of elements) is passed in
\r
281 if ( num && num.constructor == Array ) {
\r
283 // Use a tricky hack to make the jQuery object
\r
284 // look and feel like an array
\r
286 [].push.apply( this, num );
\r
290 return num == undefined ?
\r
292 // Return a 'clean' array
\r
293 jQuery.merge( this, [] ) :
\r
295 // Return just the object
\r
300 * Execute a function within the context of every matched element.
\r
301 * This means that every time the passed-in function is executed
\r
302 * (which is once for every element matched) the 'this' keyword
\r
303 * points to the specific element.
\r
305 * Additionally, the function, when executed, is passed a single
\r
306 * argument representing the position of the element in the matched
\r
309 * @example $("img").each(function(){
\r
310 * this.src = "test.jpg";
\r
312 * @before <img/> <img/>
\r
313 * @result <img src="test.jpg"/> <img src="test.jpg"/>
\r
315 * @example $("img").each(function(i){
\r
316 * alert( "Image #" + i + " is " + this );
\r
318 * @before <img/> <img/>
\r
319 * @result <img src="test.jpg"/> <img src="test.jpg"/>
\r
321 * @test var div = $("div");
\r
322 * div.each(function(){this.foo = 'zoo';});
\r
324 * for ( var i = 0; i < div.size(); i++ ) {

\r
340 * the index of the element, if found, starting with zero.
\r
