Hidden Field not updating in form
Posted on 2015-02-06
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:
This should do the trick.
