autofill textboxes

Hi
I was playing with this code and i discovered something pretty weird.

Since emails don't have spaces, I used the replace function to replace " " with "".

BUT....
ie.
First: Anna Smith
Last: Boa Wow
Email: AnnaSmith.Boa Wow <- doesn't replace the " " with ""

now isn't that weird... anyone know why? or how I can fix this?

Code: Select all

<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Untitled Document</title>
<script type="text/javascript">
function setEmail(){
var theemail = document.forms[0].fname.value+'.'+document.forms[0].lname.value;
theemail = theemail.replace(" ", "");
document.forms[0].email.value = theemail;
}
</script>
</head>

<body>
<form action="#" method="post">
<input type="text" name="fname" onKeyUp="setEmail()" size="15">
<input type="text" name="lname" onKeyUp="setEmail()" size="15">
<input type="text" name="email"  size="15">
</form>
</body>
</html>

If there email contains spaces ask them to fill it out again, no use trying to make your own by deleting spaces.

Also using javascript for validation is a bad idea because people can just disable javascript in their browser.

doesn't that defeat the purpose of what programming/scripting is all about?

Not if your going to be getting bogus code.

You have to make it so they enter the right details no use having the field otherwise.
