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

407 type ? this.style : this,
412 // Look for the case where we're accessing a style value
413 jQuery[ type || "attr" ]( this[0], key );
417 * Access a style property on the first matched element.
418 * This method makes it easy to retrieve a style property value
419 * from the first matched element.
421 * @example $("p").css("color");
422 * @before <p style="color:red;">Test Paragraph.</p>
424 * @desc Retrieves the color style of the first paragraph
426 * @example $("p").css("fontWeight");
427 * @before <p style="font-weight: bold;">Test Paragraph.</p>
429 * @desc Retrieves the font-weight style of the first paragraph.
430 * Note that for all style properties with a dash (like 'font-weight'), you have to
431 * write it in camelCase. In other words: Every time you have a '-' in a
432 * property, remove it and replace the next character with an uppercase
433 * representation of itself. Eg. fontWeight, fontSize, fontFamily, borderWidth,
434 * borderStyle, borderBottomWidth etc.
438 * @param String name The name of the property to access.
443 * Set a hash of key/value style properties to all matched elements.
444 * This serves as the best way to set a large number of style properties
445 * on all matched elements.
447 * @example $("p").css({ color: "red", background: "blue" });
448 * @before <p>Test Paragraph.</p>
449 * @result <p style="color:red; background:blue;">Test Paragraph.</p>
453 * @param Hash prop A set of key/value pairs to set as style properties.
458 * Set a single style property to a value, on all matched elements.
460 * @example $("p").css("color","red");
461 * @before <p>Test Paragraph.</p>
462 * @result <p style="color:red;">Test Paragraph.</p>
463 * @desc Changes the color of all paragraphs to red
467 * @param String key The name of the property to set.
468 * @param Object value The value to set the property to.
471 css: function( key, value ) {
472 return this.attr( key, value, "curCSS" );
476 * Retrieve the text contents of all matched elements. The result is
477 * a string that contains the combined text contents of all matched
478 * elements. This method works on both HTML and XML documents.
480 * @example $("p").text();
481 * @before <p>Test Paragraph.</p>
482 * @result Test Paragraph.
491 for ( var j = 0; j < e.length; j++ ) {

494 if ( r[i].nodeType != 8 )
495 t += r[i].nodeType != 1 ?
496 r[i].nodeValue : jQuery.fn.text([ r[i] ]);
502 * Wrap all matched elements with a structure of other elements.
503 * This wrapping process is most useful for injecting additional
504 * stucture into a document, without ruining the original semantic
505 * qualities of a document.
507 * This works by going through the first element
508 * provided (which is generated, on the fly, from the provided HTML)
509 * and finds the deepest ancestor element within its
510 * structure - it is that element that will en-wrap everything else.
512 * This does not work with elements that contain text. Any necessary text
513 * must be added after the wrapping is done.
515 * @example $("p").wrap("<div class='wrap'></div>");
516 * @before <p>Test Paragraph.</p>
517 * @result <div class='wrap'><p>Test Paragraph.</p></div>

569 * Append any number of elements to the inside of every matched elements,
570 * generated from the provided HTML.

842 * Removes all elements from the set of matched elements that do not
843 * match at least one of the expressions passed to the function. This
844 * method is used when you want to filter the set of matched elements
845 * through more than one expression.
847 * Elements will be retained in the jQuery object if they match at
848 * least one of the expressions passed.
850 * @example $("p").filter([".selected", ":first"])

888 * @param Element el An element to remove from the set
889 * @cat DOM/Traversing
893 * Removes elements matching the specified expression from the set
894 * of matched elements. This method is used to remove one or more
895 * elements from a jQuery object.
897 * @example $("p").not("#selected")
898 * @before <p>Hello</p><p id="selected">Hello Again</p>
899 * @result [ <p>Hello</p> ]

913 * Adds the elements matched by the expression to the jQuery object. This
914 * can be used to concatenate the result sets of two expressions.
916 * @example $("p").add("span")
917 * @before <p>Hello</p><p><span>Hello Again</span></p>
918 * @result [ <p>Hello</p>, <span>Hello Again</span> ]
922 * @param String expr An expression whose matched elements are added
923 * @cat DOM/Traversing
927 * Adds each of the Elements in the array to the set of matched elements.
928 * This is used to add a set of Elements to a jQuery object.
930 * @example $("p").add([document.getElementById("a"), document.getElementById("b")])
931 * @before <p>Hello</p><p><span id="a">Hello Again</span><span id="b">And Again</span></p>
932 * @result [ <p>Hello</p>, <span id="a">Hello Again</span>, <span id="b">And Again</span> ]
936 * @param Array<Element> els An array of Elements to add
937 * @cat DOM/Traversing
941 * Adds a single Element to the set of matched elements. This is used to
942 * add a single Element to a jQuery object.
944 * @example $("p").add( document.getElementById("a") )
945 * @before <p>Hello</p><p><span id="a">Hello Again</span></p>
946 * @result [ <p>Hello</p>, <span id="a">Hello Again</span> ]

961 * Checks the current selection against an expression and returns true,
962 * if at least one element of the selection fits the given expression.
963 * Does return false, if no element fits or the expression is not valid.
965 * @example $("input[@type='checkbox']").parent().is("form")
966 * @before <form><input type="checkbox" /></form>
968 * @desc Returns true, because the parent of the input is a form element
970 * @example $("input[@type='checkbox']").parent().is("form")
971 * @before <form><p><input type="checkbox" /></p></form>
973 * @desc Returns false, because the parent of the input is a p element
975 * @example $("form").is(null)
976 * @before <form></form>
978 * @desc An invalid expression always returns false.
982 * @param String expr The expression with which to filter
983 * @cat DOM/Traversing
986 return expr ? jQuery.filter(expr,this).r.length > 0 : false;
