So far jquery has been released to 1.4.2, and in the week before that they just released the 1.4 version, to see his version of the release time, it is not difficult to find his rapid development, every month in the update version; and someone has been developing new jquery Plug-ins, and recently launched a JQuery UI Library
jquery was unveiled on January 14, 2006 in BarCamp NYC (New York city). Lord John Resig, who wrote "Pro JavaScript techniques," because of the mozolla, it is said that Firefox 3 will contain jquery, now the jquery team has major developers, extension staff, UI, plug-in development, Website design maintenance, of which 3 major developers are: Two Americans John Resig/brandon Aaron, a German Jorn Zaefferer)
Here's a quick introduction to some of the features and usage of jquery:
1. Accurate and simple Selection object (DOM):
Copy Code code as follows:
$ (' #element ');//equivalent to document.getElementById ("element")
$ ('. element ');//class
$ (' P ');//html label
$ ("form > Input");//child objects
$ ("Div,span,p.myclass");//Select multiple objects at the same time
$ ("tr:odd"). CSS ("Background-color", "#bbbbff");//table interlacing background
$ (": input")//Form Object
$ ("input[name= ' newsletter ']");//Specific Form Object
2, the application of the object function is simple and unrestricted:
Copy Code code as follows:
Element.function (PAR);
$ ("P.surprise"). AddClass ("Ohmy"). Show ("Slow") ...
3. Action on selected objects (including styles):
Copy Code code as follows:
$ ("#element"). AddClass ("selected");//Add Style to Object
$ (' #element '). CSS ({"Background-color": "Yellow", "font-weight": "Bolder"}); Change object style
$ ("P"). Text ("Some new text."); /Change Object text
$ ("img"). attr ({src: "test.jpg", alt: "Test Image"});//Change Object text
$ ("P"). Add ("span");//Add label to Object
$ ("P"). FIND ("span");//Look up the corresponding element within the object
$ ("P"). parent ();//object's Parental element
$ ("P"). Append ("<b>Hello</b>");//Add content to Object
4, support AJAX, supporting file format: XML/HTML/SCRIPT/JSON/JSONP
Copy Code code as follows:
$ ("#feeds"). Load ("feeds.html")//Area import static page content
$ ("#feeds"). Load ("feeds.php", {limit:25}, function () {alert ("The last entries in the feed have been loaded"); /Import Dynamic Content
4. Support for events:
Copy Code code as follows:
$ ("P"). Hover (function () {
$ (this). addclass ("Hilite");//mouse when put up
}, function () {
$ (this). Removeclass ("Hilite");//Remove mouse
)//mouse to put up and remove different effects (automatically loop all P objects)
5, Animation:
Copy Code code as follows:
$ ("P"). Show ("slow");//hidden Object (slow gradient)
$ ("#go"). Click (function () {
$ ("#block"). Animate ({
Width: "90%",
Height: "100%",
FontSize: "10em"
}, 1000);
//mouse clicks wide, high, font dynamic changes
6, Expansion:
Copy Code code as follows:
$.fn.background = function (BG) {
return this.css (' background ', BG);
};
$ (#element). Background ("Red");
If you want to add a function to each JQuery object, you must assign the function to $.fn, and the function must return a This (jquery object)
