Question

Disable button until valid email address entered - fix code

Asked by: GessWurker

Here's a form and some code I've cut and pasted together and I'm trying to get to work. I've done something wrong however. I get "object doesn't support this method..." Who can point out the errors of my ways and fix?
The form and code:

<html>
<head>
<title>testform</title>
<script type="text/javascript" language="JavaScript" src="/dbtw-wpd/jscript/dbtw-r-main.js"></script>
<script>
function emailTest(obj){
reg=/^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/
 if (!reg.test(obj.value) )

{
                  RequestForm.submit.disabled = true;
                  obj.focus()
            }
            else
            {
                  RequestForm.submit.disabled = false;
            }
}
</script>

<body>
<form name="RequestForm" action="RequestEmail.asp" method="post"><p>
Name:  
    <input type="text" name="RequestedBy">
</p>
  <p>Extension:
    <input type="text" name="Extension">
  </p>
<p>Cube / Office No.:
    <input type="text" name="OfficeNumber">
</p>
  <p>Email Address:
    <input type="text" name="FromEmail" onKeyUp="emailTest(this)">
  </p>
  <p>  Comments:<br>
    <textarea name="comments" rows='5' cols="65">
    </textarea>
    </td>
    <input type="submit" value="Request Items" disabled>
    </p>
</form>
</body>
