[javascript] HTML form action and onsubmit issues

I want to run JavaScript user validation on some textbox entries.

The problem I'm having is that my form has the action of going to a new page within our site, and the onsubmit attribute never runs the JavaScript function.

Is there a better solution, or one that works with the following code: Note: the JavaScript file is written correctly and works if you switch the action to checkRegistration().

It is merely an issue with running both action and JavaScript.

<form name="registerForm" action="validate.html" onsubmit="checkRegistration()" method="post">
    <!-- Textboxes are here -->
    <!-- And the submit button -->
</form>

Try:

onsubmit="checkRegistration(event.preventDefault())"

Try

onsubmit="return checkRegistration()"
