I was doing some testing and I can't figure out why my hidden field is not being populated? The value stays blank.

<!DOCTYPE html>
<html lang="en">
  <head>
	<script>
	function populateUser(){
		var currUser = "test@yopmail.com";
	    document.getElementById("txtUserName").value = currUser;
	    return true
	};
	</script>

  </head>
  <body>
  	<form action="www.somedomain.com" name="loginform" method="post" target="bottom">
	  <input type="hidden" id="txtUserName" name="txtUserName" value="" />
	  <input type="submit" name="submit" onsubmit="return populateUser()" value="start logon"/>
	</form>
  </body>
</html>

Hi,
please move the onsubmit to the form element and not in the submit button:

<form action="www.somedomain.com" onsubmit="return populateUser()" name="loginform" method="post" target="bottom">
	  <input type="hidden" id="txtUserName" name="txtUserName" value="" />
	  <input type="submit" name="submit"  value="start logon"/>
	</form>

This should do the trick.
