What is jquery? How to Learn jquery well?

Jquery is a JS framework that operates the DOM tree of a webpage directly through it (the DOM tree is like the XML structure) because the tag node in HTML is a DOM tree (XML structure) in other words, jquery directly operates the tag node of the webpage. Of course, he features foreground or asynchronous webpage operations.

With the rapid development and dissemination of Web2.0 and Ajax ideas on the Internet, some excellent JS frameworks have emerged one after another, among them, the famous ones include prototype, Yui, jquery, mootools, bindows, and domestic jsvm frameworks. By applying these JS frameworks to our project, we can makeProgramDevelopers are freed from complicated JS applications in design and writing, turning their focus to functional requirements rather than implementation details, thus improving the project development speed.
Jquery is another excellent JavaScript framework after prototype. It was created by John resig in early 2006 and helps simplify JavaScript and Ajax programming. Someone uses this analogy to compare prototype and jquery: Prototype is like Java, while jquery is like Ruby. it is a simple, fast, and flexible JavaScript framework that allows you to perform simple operations on your web page.CompositionFile, process events, implement special effects, and add Ajax interactions to web pages.

It is estimated that many of the above are mentioned. Beginners must have a vague concept and should understand what jquery can bring to our programming. 1. He simplified the Javascript used in the foreground special effects.Code2. Ajax technology should be known as Asynchronous Update (that is, partial refresh ).Well, I don't want to talk much about it. Focus: Where do beginners start,To learn about jquery, you must have knowledge of HTML and CSS, because jquery operates on HTML tags, while jquery selects webpage tags through the selector in CSS to select tag nodes in webpages. of course, JavaScript knowledge is required. jquery is the JS framework.If you have all these points, you can easily learn jquery.

First download a good textbook. Here I recommend <jquery basic tutorial> the PDF cover is as follows:

Next I want to watch some videos on OK, here I recommend a suitable for beginners to watch the video http://learning.artech.cn/20080621.mastering-javascript-jquery.html

Go to some forum jquery groupsCommunityLet's take a look at the jquery group http://home.cnblogs.com/group/jquery/ in the blog.

The above is just a way to get you started. What you actually learned is what you learned from your own development.
