The following works fine in Firefox and Chrome, but IE 8 will not call the submit() method when the anchor link is clicked.
<a href="javascript:void(0);" onclick="submit();">Sign In</a>
The submit method is defined on the same page as follows:
<head>
<script type="text/javascript">
function submit()
{
// other code
document.forms[0].submit();
}
</script>
</head>
