Automatic removal of part of a form value?

[cbsarge]

I have a form that asks for a user's user ID and email address. Is there any way to remove part of the value entered for User ID if someone enters "id12345" instead of just "12345"? Sometimes users are inputting the id part also and then aren't able to log in. I don't want to just limit the field length either - I want this to be as transparent as possible. If they put in anything but text I want it stripped away.

Thanks!

<form method="post" action="check.epl">
<table border="0" cellspacing="0" cellpadding="2">
<tr> 
<td>Enter your UserID</td>
<td> 
<input type="text" name="id">
</td>
</tr>
<tr> 
<td>Enter your email address<td>
<input type="text" name="email"></tr>
</table>
<p> 
<input type="submit" name="Submit" value="Submit">
</p>
</form>

Why not start with a simple Javascript on the Client Side to ensure that the field entry is only digits, backed up by a check on the server side.

For the Javascript I can recommend the RegEx at

as a useful utility function that does what you need.

If you are sure that you are looking for the value "id" you could use INSTR in Classic ASP (

to identify and then RIGHT (

to return the number component, although there are many other ways.
