jQuery – A powerful javascript library capable of doing all your complex javascript actions and functionality in a line or two. How cool is that.
Pre-requisites : Notepad, jquery.js file(You can get it here), some coding background and an open mind
Let’s Start with a simple Hello World:
Open your notepad, create a html file as below:
<html>
<head>
<title>Hello World</title>
<script type=”text/javascript” language=”javascript” src=”jquery-1.3.2.min.js”>
<script type=”text/javascript” language=”javascript”>
$.document.ready(function(){
$(“#btnX”).click(function(){
alert(‘Hello World’);
});
});
</script>
</head>
<body>
<input id=”btnX” type=”button” value=”Click Me” />
</body>
</html>
Save the above file as “HelloWorld.html” in a Folder. Copy the jquery-1.3.2.min.js file to the same folder. Now double-click the button named “Click Me“.
Voila! An alert box pops up with “Hello World” text.
