php and javascript redirect problem

[carhbtt]

I have a php page which contains a form, within that same page I have JavaScript to validate input in the form fields, on the form I have

<FORM name="the_form" method="POST" onsubmit="validate();" action="val_checkout.php">

so when the form is submited the javascript checks for errors, if one is found I use the javascript alert() to show a pop up window but when the ok button of that pop up window is pressed the val_checkout.php
is called.

How can I avoid been redirected if an error is found?

Thanks fellas!

never mind! I found the solutioon.

You have to include a return on both the alert and the onsubmit

<FORM name="the_form" method="POST" onsubmit="return validate();" action="val_checkout.php">

and in javascript after the alert

alert("hkhk hh"); return false;

that will make it work!
