71 * This function accepts a string containing a CSS or
72 * basic XPath selector which is then used to match a set of elements.
74 * The core functionality of jQuery centers around this function.
75 * Everything in jQuery is based upon this, or uses this in some way.
76 * The most basic use of this function is to pass in an expression
77 * (usually consisting of CSS or XPath), which then finds all matching
80 * By default, $() looks for DOM elements within the context of the
81 * current HTML document.
83 * @example $("div > p")
84 * @desc Finds all p elements that are children of a div element.
85 * @before <p>one</p> <div><p>two</p></div> <p>three</p>
86 * @result [ <p>two</p> ]
88 * @example $("input:radio", document.forms[0])
89 * @desc Searches for all inputs of type radio within the first form in the document
91 * @example $("div", xml.responseXML)
92 * @desc This finds all div elements within the specified XML document.
95 * @param String expr An expression to search with
96 * @param Element|jQuery context (optional) A DOM Element, Document or jQuery to use as context
100 * @see $(Element<Array>)
104 * Create DOM elements on-the-fly from the provided String of raw HTML.
106 * @example $("<div><p>Hello</p></div>").appendTo("#body")
107 * @desc Creates a div element (and all of its contents) dynamically,
108 * and appends it to the element with the ID of body. Internally, an
109 * element is created and it's innerHTML property set to the given markup.
110 * It is therefore both quite flexible and limited.
113 * @param String html A string of HTML to create on the fly.
116 * @see appendTo(String)
120 * Wrap jQuery functionality around a single or multiple DOM Element(s).
122 * This function also accepts XML Documents and Window objects
123 * as valid arguments (even though they are not DOM Elements).
125 * @example $(document).find("div > p")
126 * @before <p>one</p> <div><p>two</p></div> <p>three</p>
127 * @result [ <p>two</p> ]
128 * @desc Same as $("div > p") because the document
130 * @example $(document.body).background( "black" );
131 * @desc Sets the background color of the page to black.
133 * @example $( myForm.elements ).hide()
134 * @desc Hides all the input elements within a form
137 * @param Element|Array<Element> elems DOM element(s) to be encapsulated by a jQuery object.
143 * A shorthand for $(document).ready(), allowing you to bind a function
144 * to be executed when the DOM document has finished loading. This function
145 * behaves just like $(document).ready(), in that it should be used to wrap
146 * all of the other $() operations on your page. While this function is,
147 * technically, chainable - there really 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.
186 * @example $("img").length;
187 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
197 * The number of elements currently matched.
199 * @example $("img").size();
200 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
214 * Access all matched elements. This serves as a backwards-compatible
215 * way of accessing all matched elements (other than the jQuery object
216 * itself, which is, in fact, an array of elements).
218 * @example $("img").get();
219 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
220 * @result [ <img src="test1.jpg"/> <img src="test2.jpg"/> ]
221 * @desc Selects all images in the document and returns the DOM Elements as an Array
224 * @type Array<Element>
229 * Access a single matched element. num is used to access the
230 * Nth element matched.
232 * @example $("img").get(0);
233 * @before <img src="test1.jpg"/> <img src="test2.jpg"/>
234 * @result [ <img src="test1.jpg"/> ]
235 * @desc Selects all images in the document and returns the first one
239 * @param Number num Access the element in the Nth position.
242 get: function( num ) {
243 return num == undefined ?
245 // Return a 'clean' array
246 jQuery.makeArray( this ) :
248 // Return just the object
253 * Set the jQuery object to an array of elements, while maintaining
256 * @example $("img").pushStack([ document.body ]);
257 * @result $("img").pushStack() == [ document.body ]
262 * @param Elements elems An array of elements
265 pushStack: function( a ) {
266 var ret = jQuery(this);
267 ret.prevObject = this;
268 return ret.setArray( a );
272 * Set the jQuery object to an array of elements. This operation is
273 * completely destructive - be sure to use .pushStack() if you wish to maintain
276 * @example $("img").setArray([ document.body ]);
277 * @result $("img").setArray() == [ document.body ]
282 * @param Elements elems An array of elements
285 setArray: function( a ) {
287 [].push.apply( this, a );
292 * Execute a function within the context of every matched element.
293 * This means that every time the passed-in function is executed
294 * (which is once for every element matched) the 'this' keyword
295 * points to the specific element.
297 * Additionally, the function, when executed, is passed a single
298 * argument representing the position of the element in the matched
301 * @example $("img").each(function(i){
302 * this.src = "test" + i + ".jpg";
304 * @before <img/><img/>
305 * @result <img src="test0.jpg"/><img src="test1.jpg"/>
306 * @desc Iterates over two images and sets their src property
310 * @param Function fn A function to execute
313 each: function( fn, args ) {
314 return jQuery.each( this, fn, args );
318 * Searches every matched element for the object and returns
319 * the index of the element, if found, starting with zero.
320 * Returns -1 if the object wasn't found.
322 * @example $("*").index( $('#foobar')[0] )
323 * @before <div id="foobar"></div><b></b><span id="foo"></span>
325 * @desc Returns the index for the element with ID foobar
327 * @example $("*").index( $('#foo'))
328 * @before <div id="foobar"></div><b></b><span id="foo"></span>
330 * @desc Returns the index for the element with ID foo
332 * @example $("*").index( $('#bar'))
333 * @before <div id="foobar"></div><b></b><span id="foo"></span>
335 * @desc Returns -1, as there is no element with ID bar
339 * @param Element subject Object to search for
342 index: function( obj ) {
344 this.each(function(i){
345 if ( this == obj ) pos = i;
351 * Access a property on the first matched element.
352 * This method makes it easy to retrieve a property value
353 * from the first matched element.
355 * @example $("img").attr("src");
356 * @before <img src="test.jpg"/>
358 * @desc Returns the src attribute from the first image in the document.
362 * @param String name The name of the property to access.
363 * @cat DOM/Attributes
367 * Set a key/value object as properties to all matched elements.
369 * This serves as the best way to set a large number of properties
370 * on all matched elements.
372 * @example $("img").attr({ src: "test.jpg", alt: "Test Image" });
374 * @result <img src="test.jpg" alt="Test Image"/>
375 * @desc Sets src and alt attributes to all images.
379 * @param Map properties Key/value pairs to set as object properties.
380 * @cat DOM/Attributes
384 * Set a single property to a value, on all matched elements.
386 * Can compute values provided as ${formula}, see second example.
388 * Note that you can't set the name property of input elements in IE.
389 * Use $(html) or .append(html) or .html(html) to create elements
390 * on the fly including the name property.
392 * @example $("img").attr("src","test.jpg");
394 * @result <img src="test.jpg"/>
395 * @desc Sets src attribute to all images.
397 * @example $("img").attr("title", "${this.src}");
398 * @before <img src="test.jpg" />
399 * @result <img src="test.jpg" title="test.jpg" />
400 * @desc Sets title attribute from src attribute, a shortcut for attr(String,Function)
404 * @param String key The name of the property to set.
405 * @param Object value The value to set the property to.
406 * @cat DOM/Attributes
410 * Set a single property to a computed value, on all matched elements.
412 * Instead of a value, a function is provided, that computes the value.
414 * @example $("img").attr("title", function() { return this.src });
415 * @before <img src="test.jpg" />
416 * @result <img src="test.jpg" title="test.jpg" />
417 * @desc Sets title attribute from src attribute.
421 * @param String key The name of the property to set.
422 * @param Function value A function returning the value to set.

449 * Access a style property on the first matched element.
450 * This method makes it easy to retrieve a style property value
451 * from the first matched element.

465 * @param String name The name of the property to access.
470 * Set a key/value object as style properties to all matched elements.
472 * This serves as the best way to set a large number of style properties
473 * on all matched elements.

476 * @before <p>Test Paragraph.</p>
477 * @result <p style="color:red; background:blue;">Test Paragraph.</p>
478 * @desc Sets color and background styles to all p elements.
482 * @param Map properties Key/value pairs to set as style properties.
487 * Set a single style property to a value, on all matched elements.
488 * If a number is provided, it is automatically converted into a pixel value.
490 * @example $("p").css("color","red");
491 * @before <p>Test Paragraph.</p>
492 * @result <p style="color:red;">Test Paragraph.</p>
493 * @desc Changes the color of all paragraphs to red
495 * @example $("p").css("left",30);

503 * @param String|Number value The value to set the property to.
506 css: function( key, value ) {
507 return this.attr( key, value, "curCSS" );
511 * Get the text contents of all matched elements. The result is
512 * a string that contains the combined text contents of all matched
513 * elements. This method works on both HTML and XML documents.
515 * @example $("p").text();
516 * @before <p><b>Test</b> Paragraph.</p><p>Paraparagraph</p>
517 * @result Test Paragraph.Paraparagraph
518 * @desc Gets the concatenated text of all paragraphs

528 * Similar to html(), but escapes HTML (replace "<" and ">" with their
531 * @example $("p").text("<b>Some</b> new text.");
532 * @before <p>Test Paragraph.</p>
533 * @result <p><b>Some</b> new text.</p>

552 this.each(function(){ this[ type ] = e; });
556 * Wrap all matched elements with a structure of other elements.
557 * This wrapping process is most useful for injecting additional
558 * stucture into a document, without ruining the original semantic
559 * qualities of a document.
561 * This works by going through the first element
562 * provided (which is generated, on the fly, from the provided HTML)
563 * and finds the deepest ancestor element within its
564 * structure - it is that element that will en-wrap everything else.
566 * This does not work with elements that contain text. Any necessary text
567 * must be added after the wrapping is done.

1178 * to whichever library first implemented it. This helps to make
1179 * sure that jQuery doesn't conflict with the $ object
1180 * of other libraries.
1182 * By using this function, you will only be able to access jQuery
1183 * using the 'jQuery' variable. For example, where you used to do
1184 * $("div p"), you now must do jQuery("div p").
1186 * @example jQuery.noConflict();
1187 * // Do something with jQuery
1188 * jQuery("div p").hide();
1189 * // Do something with another library's $()
1190 * $("content").style.display = 'none';

1193 * @example jQuery.noConflict();
1196 * // more code using $ as alias to jQuery
1199 * // other code using $ as an alias to the other library
1200 * @desc Reverts the $ alias and then creates and executes a
1201 * function to provide the $ as a jQuery alias inside the functions
1202 * scope. Inside the function the original $ object is not available.
1203 * This works well for most plugins that don't rely on any other library.
1206 * @name $.noConflict
1210 noConflict: function() {
1216 * A generic iterator function, which can be used to seemlessly

1218 * as $().each() - which is used to iterate, exclusively, over a jQuery
1219 * object. This function can be used to iterate over anything.
1221 * The callback has two arguments:the key (objects) or index (arrays) as first
1222 * the first, and the value as the second.
