edit fields problem

[sokratees9]

Hi

I'm pretty new to using javascript, so hopefully this problem shouldn't be too hard for some of you out there to solve.

I've set up a very simple form with a password field and a submit button. when i type in the (correct) password and press the submit button, everything is fine, it takes me to the appropriate place, but when i type in the correct password and simply hit enter, the page just reloads. any idea how i can sort this out. heres the code that i currently have

for the edit field;

<input type="text" name="User" size="15" onKeyPress="checkEnter(event)">

and the javascript;

<script language="JavaScript">
NS4 = (document.layers) ? true : false;

function checkEnter(event)
{
var code = 0;

if (NS4)
code = event.which;
else
code = event.keyCode;
if (code==13)
document.passwd.submit();
}
</script>

any help would be great
Thanks in advance
Sok
