Example of javascript validation on form controls before a postback

I am designing a web-form to save some data. I am relatively new in this field .

Can someone give some exmamples of how to implement validations on form controls using javascript before a postback occurs.

Meaning, if the validations return true ( indicating some field missing ) then we don't do the postback and vice-versa.

Thanks,

Mangesh

Ya you can use form with onSubmit function. as shown below

<form onsubmit="return Validate()">
... your controls will go here with submit button...
</form>

<script type="text/javascript">
    function Validate() {
               do your validations here all goes well return true else return false        
    }
</script>

Hope this answered your question
