How to use JQuery

Jquery is JavaScript Library

It is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development.

jQuery is designed to change the way that you write JavaScript.

How to use JQuery ?

To use JQuery we need to add below code

< script type="text/javascript" src="jquery.js"> < /script >

But remember if jquery.js is in the same directory as your HTML file, then give give the above path.I will suggest to make javascript in separate directory, like "/_js" folder , In that folder you can include your update version jquery.js and your own JS file which you use in your site like "global.js"

So path can be :

< script type="text/javascript" src="_js/jquery.js"> < /script >
< script type="text/javascript" src="_js/global.js"> < /script >

You can download your new version of jQuery.js from the Jquery.com

jQuery has a simple statement that checks the document and waits until it's ready to be manipulated, known as the ready event

 $(document).ready(function(){
// Your code here
});

Example :

Inside the ready event, I have added click handler to the link:


$(document).ready(function(){
$("a").click(function(event){
alert("It is easy......");
});
});

If you want the convenience of the $ function for jQuery without colliding
some other use of the global $ function,the jQuery documentation suggests the
following :

(function($) {
// Within this block, $ is a reference to jQuery
});
