fill in text field twice to confirm

[bsxiong]

how do make it so that the user have to enter their email twice in a form. Like their two email has to match up or else when hey submit, they get an error.

<script type="text/javascript">
function checkEmail() {
email = document.getElementById('email').value;
confirm_email = document.getElementById('confirm-email').value;
if(email == confirm_email) {
return true;
}
else {
alert("E-mails don't match");
return false;
}
}
</script>
<form action="" method="post" onsubmit="return checkEmail()">
<input type="text" name="email" id="email" />
<input type="text" name="confirm_e-mail" id="confirm-email" />
<input type="submit" />
</form>
