77 * This function accepts a string containing a CSS selector,
78 * basic XPath, or raw HTML, which is then used to match a set of elements.
79 * The HTML string is different from the traditional selectors in that
80 * it creates the DOM elements representing that HTML string, on the fly,
81 * to be (assumedly) inserted into the document later.
83 * The core functionality of jQuery centers around this function.
84 * Everything in jQuery is based upon this, or uses this in some way.
85 * The most basic use of this function is to pass in an expression
86 * (usually consisting of CSS or XPath), which then finds all matching
87 * elements and remembers them for later use.
89 * By default, $() looks for DOM elements within the context of the
90 * current HTML document.
92 * @example $("div > p")
93 * @desc This finds all p elements that are children of a div element.
94 * @before <p>one</p> <div><p>two</p></div> <p>three</p>
95 * @result [ <p>two</p> ]
97 * @example $("<div><p>Hello</p></div>").appendTo("#body")
98 * @desc Creates a div element (and all of its contents) dynamically, and appends it to the element with the ID of body.
101 * @param String expr An expression to search with, or a string of HTML to create on the fly.
107 * This function accepts a string containing a CSS selector, or
108 * basic XPath, which is then used to match a set of elements with the
109 * context of the specified DOM element, or document
111 * @example $("div", xml.responseXML)
112 * @desc This finds all div elements within the specified XML document.
115 * @param String expr An expression to search with.
116 * @param Element context A DOM Element, or Document, representing the base context.
122 * Wrap jQuery functionality around a specific DOM Element.
123 * This function also accepts XML Documents and Window objects
124 * as valid arguments (even though they are not DOM Elements).
126 * @example $(document).find("div > p")
127 * @before <p>one</p> <div><p>two</p></div> <p>three</p>
128 * @result [ <p>two</p> ]
130 * @example $(document).ready( loaded );
131 * @desc Executes the "loaded" function when the DOM is ready to
135 * @param Element elem A DOM element to be encapsulated by a jQuery object.
141 * Wrap jQuery functionality around a set of DOM Elements.
143 * @example $( myForm.elements ).hide()
144 * @desc Hides all the input elements within a form
147 * @param Array<Element> elems An array of DOM elements to be encapsulated by a jQuery object.
153 * A shorthand for $(document).ready(), allowing you to bind a function
154 * to be executed when the DOM document has finished loading.
156 * @example $( loaded )
157 * @desc Executes the function "loaded" when the DOM is ready to be used.
160 * @param Function fn The function to execute when the DOM is ready.
166 * A means of creating a duplicate copy of a jQuery object.
168 * @example var div = $("div");
170 * @desc Locates all p elements with all div elements, without disrupting the original jQuery object contained in 'div'.
173 * @param jQuery obj The jQuery object to be cloned.
178 // Map the jQuery namespace to the '$' one
181 jQuery.fn = jQuery.prototype = {
183 * The current SVN version of jQuery.
194 * The number of elements currently matched.
196 * @example $("img").length;
197 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
200 * @test cmpOK( $("div").length, "==", 2, "Get Number of Elements Found" );
209 * The number of elements currently matched.
211 * @example $("img").size();
212 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
215 * @test cmpOK( $("div").size(), "==", 2, "Get Number of Elements Found" );
226 * Access all matched elements. This serves as a backwards-compatible
227 * way of accessing all matched elements (other than the jQuery object
228 * itself, which is, in fact, an array of elements).
230 * @example $("img").get();
231 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
232 * @result [ <img src="test1.jpg"/> <img src="test2.jpg"/> ]
234 * @test isSet( $("div").get(), q("main","foo"), "Get All Elements" );
237 * @type Array<Element>
242 * Access a single matched element. num is used to access the
243 * Nth element matched.
245 * @example $("img").get(1);
246 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
247 * @result [ <img src="test1.jpg"/> ]
249 * @test cmpOK( $("div").get(0), "==", document.getElementById("main"), "Get A Single Element" );
253 * @param Number num Access the element in the Nth position.
258 * Set the jQuery object to an array of elements.
260 * @example $("img").get([ document.body ]);
261 * @result $("img").get() == [ document.body ]
266 * @param Elements elems An array of elements
269 get: function( num ) {
270 // Watch for when an array (of elements) is passed in
271 if ( num && num.constructor == Array ) {
273 // Use a tricky hack to make the jQuery object
274 // look and feel like an array
276 [].push.apply( this, num );
280 return num == undefined ?
282 // Return a 'clean' array
283 jQuery.map( this, function(a){ return a } ) :
285 // Return just the object
290 * Execute a function within the context of every matched element.
291 * This means that every time the passed-in function is executed
292 * (which is once for every element matched) the 'this' keyword
293 * points to the specific element.
295 * Additionally, the function, when executed, is passed a single
296 * argument representing the position of the element in the matched
299 * @example $("img").each(function(){
300 * this.src = "test.jpg";
302 * @before <img/> <img/>
303 * @result <img src="test.jpg"/> <img src="test.jpg"/>
305 * @example $("img").each(function(i){
306 * alert( "Image #" + i + " is " + this );
308 * @before <img/> <img/>
309 * @result <img src="test.jpg"/> <img src="test.jpg"/>
311 * @test var div = $("div");
312 * div.each(function(){this.foo = 'zoo';});
314 * for ( var i = 0; i < div.size(); i++ ) {
315 * if ( div.get(i).foo != "zoo" ) pass = false;
317 * ok( pass, "Execute a function, Relative" );
321 * @param Function fn A function to execute
324 each: function( fn, args ) {
325 return jQuery.each( this, fn, args );
328 index: function( obj ) {
330 this.each(function(i){
331 if ( this == obj ) pos = i;
337 * Access a property on the first matched element.
338 * This method makes it easy to retreive a property value
339 * from the first matched element.
341 * @example $("img").attr("src");
342 * @before <img src="test.jpg"/>
347 * @param String name The name of the property to access.
352 * Set a hash of key/value object properties to all matched elements.
353 * This serves as the best way to set a large number of properties
354 * on all matched elements.
356 * @example $("img").attr({ src: "test.jpg", alt: "Test Image" });
358 * @result <img src="test.jpg" alt="Test Image"/>
360 * @test var pass = true;
361 * $("div").attr({foo: 'baz', zoo: 'ping'}).each(function(){
362 * if ( this.getAttribute('foo') != "baz" && this.getAttribute('zoo') != "ping" ) pass = false;
364 * ok( pass, "Set Multiple Attributes" );
368 * @param Hash prop A set of key/value pairs to set as object properties.
373 * Set a single property to a value, on all matched elements.
375 * @example $("img").attr("src","test.jpg");
377 * @result <img src="test.jpg"/>

380 * div.attr("foo", "bar");
382 * for ( var i = 0; i < div.size(); i++ ) {
383 * if ( div.get(i).getAttribute('foo') != "bar" ) pass = false;
385 * ok( pass, "Set Attribute" );
389 * @param String key The name of the property to set.
390 * @param Object value The value to set the property to.

466 * Retreive the text contents of all matched elements. The result is
467 * a string that contains the combined text contents of all matched
468 * elements. This method works on both HTML and XML documents.
470 * @example $("p").text();

492 * Wrap all matched elements with a structure of other elements.
493 * This wrapping process is most useful for injecting additional
494 * stucture into a document, without ruining the original semantic
495 * qualities of a document.
497 * This works by going through the first element
498 * provided (which is generated, on the fly, from the provided HTML)

820 * @cat DOM/Traversing
824 * Removes all elements from the set of matched elements that do not
825 * match at least one of the expressions passed to the function. This
826 * method is used when you want to filter the set of matched elements
827 * through more than one expression.
829 * Elements will be retained in the jQuery object if they match at
830 * least one of the expressions passed.
832 * @example $("p").filter([".selected", ":first"])

860 * Removes the specified Element from the set of matched elements. This
861 * method is used to remove a single Element from a jQuery object.
863 * @example $("p").not( document.getElementById("selected") )
864 * @before <p>Hello</p><p id="selected">Hello Again</p>
865 * @result [ <p>Hello</p> ]
869 * @param Element el An element to remove from the set
870 * @cat DOM/Traversing
874 * Removes elements matching the specified expression from the set
875 * of matched elements. This method is used to remove one or more
876 * elements from a jQuery object.
878 * @example $("p").not("#selected")
879 * @before <p>Hello</p><p id="selected">Hello Again</p>
