[Webdev] Javascript onsubmit() driving me bonkers !

[JustinMacCarthy]

I've never had that problem,

eg

<script>
function test()
{ return true; }
</script>
.
.
.
<form action="page2.htm" method="post" onsubmit="return test();">
<input type="Submit">
</form>

will submit but

<script>
function test()
{ return false; }
</script>
.
.
.
<form action="page2.htm" method="post" onsubmit="return test();">
<input type="Submit">
</form>

won't submit..

Haven't tried it under Linux /NS though..

The only issue I've had with onsubmit is that it doesn't get called when you
use document.forms[0].submit();
