JavaScript :
Javascript is widely using scripting language in all the web application, and here
we have provided you an easy interface to learn javascript step by step.
In this tutorial we have written the common usage of JavaScript in web applications
:
- Basics of JavaScript
- Validations & Events
- Exception Handling
- Debugging
- Dynamically creting controls
- XML
- AJAX using javascript and more....
We can
write Javascript in two places.
1.
between head tags
2.
between body tags
When we
write the Javascript between the <head></head> tags then
the script will be executed in client side.
When we
write the Javascript between the <body></body> tags then
the script will be executed in the server side.
i.e. the
script written in between the body tags will be executed before the page loads
at the client machine (In the server itself). And the script written in between
the head tag will be executed after the page loads at the client side.
Example:
Between
head tags:
-----------------------------
<head>
<script language='javascript'>
alert('between head')
</script>
</head>
Between
body tags:
-----------------------------
<body>
<script language='javascript'>
alert('between body')
</script>
</body>
