\r
76 * This function accepts a string containing a CSS or
\r
77 * basic XPath selector which is then used to match a set of elements.
\r
79 * The core functionality of jQuery centers around this function.
\r
80 * Everything in jQuery is based upon this, or uses this in some way.
\r
81 * The most basic use of this function is to pass in an expression
\r
82 * (usually consisting of CSS or XPath), which then finds all matching
\r
85 * By default, $() looks for DOM elements within the context of the
\r
86 * current HTML document.
\r
88 * @example $("div > p")
\r
89 * @desc This finds all p elements that are children of a div element.
\r
90 * @before <p>one</p> <div><p>two</p></div> <p>three</p>
\r
91 * @result [ <p>two</p> ]
\r
93 * @example $("input:radio", document.forms[0])
\r
94 * @desc Searches for all inputs of type radio within the first form in the document
\r
96 * @example $("div", xml.responseXML)
\r
97 * @desc This finds all div elements within the specified XML document.
\r
100 * @param String expr An expression to search with
\r
101 * @param Element context (optional) A DOM Element, or Document, representing the base context.
\r
105 * @see $(Element<Array>)
\r
109 * This function accepts a string of raw HTML.
\r
111 * The HTML string is different from the traditional selectors in that
\r
112 * it creates the DOM elements representing that HTML string, on the fly,
\r
113 * to be (assumedly) inserted into the document later.
\r
115 * @example $("<div><p>Hello</p></div>").appendTo("#body")
\r
116 * @desc Creates a div element (and all of its contents) dynamically,
\r
117 * and appends it to the element with the ID of body. Internally, an
\r
118 * element is created and it's innerHTML property set to the given markup.
\r
119 * It is therefore both quite flexible and limited.
\r
122 * @param String html A string of HTML to create on the fly.
\r
128 * Wrap jQuery functionality around a specific DOM Element.
\r
129 * This function also accepts XML Documents and Window objects
\r
130 * as valid arguments (even though they are not DOM Elements).
\r
132 * @example $(document).find("div > p")
\r
133 * @before <p>one</p> <div><p>two</p></div> <p>three</p>
\r
134 * @result [ <p>two</p> ]
\r
136 * @example $(document.body).background( "black" );
\r
137 * @desc Sets the background color of the page to black.
\r
140 * @param Element elem A DOM element to be encapsulated by a jQuery object.
\r
146 * Wrap jQuery functionality around a set of DOM Elements.
\r
148 * @example $( myForm.elements ).hide()
\r
149 * @desc Hides all the input elements within a form
\r
152 * @param Array<Element> elems An array of DOM elements to be encapsulated by a jQuery object.
\r
158 * A shorthand for $(document).ready(), allowing you to bind a function
\r
159 * to be executed when the DOM document has finished loading. This function
\r
160 * behaves just like $(document).ready(), in that it should be used to wrap
\r
161 * all of the other $() operations on your page. While this function is,
\r
162 * technically, chainable - there really isn't much use for chaining against it.
\r
163 * You can have as many $(document).ready events on your page as you like.
\r
165 * @example $(function(){
\r
166 * // Document is ready
\r
168 * @desc Executes the function when the DOM is ready to be used.
\r
171 * @param Function fn The function to execute when the DOM is ready.
\r
177 * A means of creating a cloned copy of a jQuery object. This function
\r
178 * copies the set of matched elements from one jQuery object and creates
\r
179 * another, new, jQuery object containing the same elements.
\r
181 * @example var div = $("div");
\r
182 * $( div ).find("p");
\r
183 * @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
186 * @param jQuery obj The jQuery object to be cloned.
\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
217 * The number of elements currently matched.
\r
219 * @example $("img").size();
\r
220 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
\r
228 return this.length;
\r
232 * Access all matched elements. This serves as a backwards-compatible
\r
233 * way of accessing all matched elements (other than the jQuery object
\r
234 * itself, which is, in fact, an array of elements).
\r
236 * @example $("img").get();
\r
237 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
\r
238 * @result [ <img src="test1.jpg"/> <img src="test2.jpg"/> ]
\r
241 * @type Array<Element>
\r
246 * Access a single matched element. num is used to access the
\r
247 * Nth element matched.
\r
249 * @example $("img").get(1);
\r
250 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
\r
251 * @result [ <img src="test1.jpg"/> ]
\r
255 * @param Number num Access the element in the Nth position.
\r
258 get: function( num ) {
\r
259 return num == undefined ?
\r
261 // Return a 'clean' array
\r
262 jQuery.merge( this, [] ) :
\r
264 // Return just the object
\r
269 * Set the jQuery object to an array of elements.
\r
271 * @example $("img").set([ document.body ]);
\r
272 * @result $("img").set() == [ document.body ]
\r
277 * @param Elements elems An array of elements
\r
280 set: function( array ) {
\r
281 // Use a tricky hack to make the jQuery object
\r
282 // look and feel like an array
\r
284 [].push.apply( this, array );
\r
289 * Execute a function within the context of every matched element.
\r
290 * This means that every time the passed-in function is executed
\r
291 * (which is once for every element matched) the 'this' keyword
\r
292 * points to the specific element.
\r
294 * Additionally, the function, when executed, is passed a single
\r
295 * argument representing the position of the element in the matched
\r
298 * @example $("img").each(function(i){
\r
299 * this.src = "test" + i + ".jpg";
\r
301 * @before <img/> <img/>
\r
302 * @result <img src="test0.jpg"/> <img src="test1.jpg"/>
\r
303 * @desc Iterates over two images and sets their src property
\r
307 * @param Function fn A function to execute
\r
310 each: function( fn, args ) {
\r
311 return jQuery.each( this, fn, args );
\r
315 * Searches every matched element for the object and returns
\r
316 * the index of the element, if found, starting with zero.
\r
317 * Returns -1 if the object wasn't found.
\r
319 * @example $("*").index(document.getElementById('foobar'))
\r
320 * @before <div id="foobar"></div><b></b><span id="foo"></span>
\r
323 * @example $("*").index(document.getElementById('foo'))
\r
324 * @before <div id="foobar"></div><b></b><span id="foo"></span>
\r
327 * @example $("*").index(document.getElementById('bar'))
\r
328 * @before <div id="foobar"></div><b></b><span id="foo"></span>
\r
333 * @param Object obj Object to search for
\r
336 index: function( obj ) {
\r
338 this.each(function(i){
\r
339 if ( this == obj ) pos = i;
\r
345 * Access a property on the first matched element.
\r
346 * This method makes it easy to retrieve a property value
\r
347 * from the first matched element.
\r
349 * @example $("img").attr("src");
\r
350 * @before <img src="test.jpg"/>
\r
355 * @param String name The name of the property to access.
\r
360 * Set a hash of key/value object properties to all matched elements.
\r
361 * This serves as the best way to set a large number of properties
\r
362 * on all matched elements.
\r
364 * @example $("img").attr({ src: "test.jpg", alt: "Test Image" });
\r
366 * @result <img src="test.jpg" alt="Test Image"/>
\r
370 * @param Hash prop A set of key/value pairs to set as object properties.
\r
375 * Set a single property to a value, on all matched elements.
\r
377 * Note that you can't set the name property of input elements in IE.
\r
378 * Use $(html) or $().append(html) or $().html(html) to create elements
\r
379 * on the fly including the name property.
\r
381 * @example $("img").attr("src","test.jpg");
\r
383 * @result <img src="test.jpg"/>
\r
387 * @param String key The name of the property to set.
\r
388 * @param Object value The value to set the property to.

\r
417 * Access a style property on the first matched element.
\r
418 * This method makes it easy to retrieve a style property value
\r
419 * from the first matched element.
\r
421 * @example $("p").css("color");
\r
422 * @before <p style="color:red;">Test Paragraph.</p>
\r
424 * @desc Retrieves the color style of the first paragraph
\r
426 * @example $("p").css("fontWeight");
\r
427 * @before <p style="font-weight: bold;">Test Paragraph.</p>
\r
429 * @desc Retrieves the font-weight style of the first paragraph.
\r
430 * Note that for all style properties with a dash (like 'font-weight'), you have to
\r
431 * write it in camelCase. In other words: Every time you have a '-' in a
\r
432 * property, remove it and replace the next character with an uppercase
\r
433 * representation of itself. Eg. fontWeight, fontSize, fontFamily, borderWidth,
\r
434 * borderStyle, borderBottomWidth etc.
\r
438 * @param String name The name of the property to access.
\r
443 * Set a hash of key/value style properties to all matched elements.
\r
444 * This serves as the best way to set a large number of style properties
\r

\r
447 * @example $("p").css({ color: "red", background: "blue" });

449 * @result <p style="color:red; background:blue;">Test Paragraph.</p>
\r
453 * @param Hash prop A set of key/value pairs to set as style properties.
\r
458 * Set a single style property to a value, on all matched elements.

460 * @example $("p").css("color","red");
\r
461 * @before <p>Test Paragraph.</p>
\r
462 * @result <p style="color:red;">Test Paragraph.</p>
\r
463 * @desc Changes the color of all paragraphs to red
\r
467 * @param String key The name of the property to set.
\r
468 * @param Object value The value to set the property to.
\r
471 css: function( key, value ) {
\r

\r
476 * Retrieve the text contents of all matched elements. The result is
\r
477 * a string that contains the combined text contents of all matched
\r
478 * elements. This method works on both HTML and XML documents.
\r
480 * @example $("p").text();
\r
481 * @before <p>Test Paragraph.</p>
\r
482 * @result Test Paragraph.

\r
502 * Wrap all matched elements with a structure of other elements.
\r
503 * This wrapping process is most useful for injecting additional
\r
504 * stucture into a document, without ruining the original semantic
\r
505 * qualities of a document.
\r
507 * This works by going through the first element
\r
508 * provided (which is generated, on the fly, from the provided HTML)
\r
509 * and finds the deepest ancestor element within its
\r
510 * structure - it is that element that will en-wrap everything else.
\r
512 * This does not work with elements that contain text. Any necessary text
\r
513 * must be added after the wrapping is done.

\r
838 * @cat DOM/Traversing
\r
842 * Removes all elements from the set of matched elements that do not
\r
843 * match at least one of the expressions passed to the function. This
\r
844 * method is used when you want to filter the set of matched elements
\r
845 * through more than one expression.
\r
847 * Elements will be retained in the jQuery object if they match at
\r
848 * least one of the expressions passed.

\r
889 * @cat DOM/Traversing
\r
893 * Removes elements matching the specified expression from the set
\r
894 * of matched elements. This method is used to remove one or more

913 * Adds the elements matched by the expression to the jQuery object. This
\r
914 * can be used to concatenate the result sets of two expressions.
\r
916 * @example $("p").add("span")
\r
917 * @before <p>Hello</p><p><span>Hello Again</span></p>

\r
963 * @example $("input[@type='checkbox']").parent().is("form")
