how take jQuery in use......

jQuery is a JavaScript framework, purpose is to make it much easier to use JavaScript on your website. jQuery as an abstraction layer, since it takes a lot of the functionality that you would have to write many lines of JavaScript to accomplish and wraps it into functions that you can call with a single line of code.

Important note is JQuery doesn't replace Javascript. The code you write in JQuery is still a Javascript in behind.

The power, the wide range of plugins and the beautiful syntax is what makes jQuery such a great framework.

Learning curve: You don't have to be javascript expert to learn JQuery. You can start learning JQuery with little knowledge in Javascript.

Here are few important links,

Hope this helps.

jquery is a library that makes it easier to do things with javascript, such as AJAX calls or manipulate the DOM. This is a very broad question, you'd do better to do a google and read first, or if you have, don't make your question sound like you've done nothing to investigate for yourself.

You should learn jquery if you do any web work. There's really nothing else that comes close.
