        <input name="btn1" type="button" onclick="a();"/>
        <a href="Reg.jsp">Register Now!</a>
    </form></font></body>
</html>

how do i cause the form to post to another page? Am I doing it correct? I want this to happen ONLY if validation passes.

Hi Alex,

Please check the sample below:

<html>
<head>
<script type="text/javascript">
function validateForm()
{
var x=document.forms["myForm"]["fname"].value;
if (x==null || x=="")
  {
  alert("First name must be filled out");
  return false;
  }
}
</script>
</head>

<body>
<form name="myForm" action="demo_form.asp" onsubmit="return validateForm()" method="post">
First name: <input type="text" name="fname">
<input type="submit" value="Submit">
</form>
</body>

</html>
