How to confirm before submitting a form with popup box

This will come in handy if you want to confirm before deletion. Modify your submit button to this:

<input type="Submit" name="Delete" value="Delete"
onClick="return confirmSubmit()">

The important part here is the onClick attribute.
And then add this somewhere on your page on top of the form:

<script LANGUAGE="JavaScript">
function confirmSubmit()
var agree=confirm("Are you sure you wish to continue?");
if (agree)
 return true ;
 return false ;
// -->

That should do the trick :)
