Data Validation

DonP · May 9, 2001

How can I validate an e-mail address from a form? What I want is a simple popup asking that it be entered again and then compared with what has already been entered to see if it's the same. I would prefer to load the JavaScript code from an external file to minimize the JavaScript code that is in the html document itself. I know how to load in external code, but not how to actually write and impliment it! How can I do this?

The form tag is simply:
[tt]<input type="text" name="E-Mail" size=40 maxlength=60>[/tt]

Thanks, This JavaScript is very nice and sophisticated but is not what I was looking to do. I don't care so much if the e-mail address is valid or not (I know that doesn't make sense) but only that the person can type it twice the same way. I do not have the option of rewriting the Perl script to which the form is being submitted so I want a popup when they submit the form that asks them to type the address again and then compare that to the one they typed in the orogonal form. Right or wrong, if it's typed the same both times, I want the form to then submit the form normally.

Here's a real quick example of what I think you're wanting to do:

Code:

<html>
<head>
<script language=&quot;javascript&quot;>
function checkemail() {
email1=document.forms[0].email1.value
email2=prompt('Please enter your e-mail address again.',&quot;&quot;)
if (email1!=email2) {
alert(&quot;E-mail addresses do not match.&quot;)
return false
}
else {
return true
}
}
</script>
</head>
<body>
<form onsubmit=&quot;return checkemail()&quot;>
Email: <input type=&quot;text&quot; name=&quot;email1&quot; /> 
<input type=&quot;submit&quot; value=&quot;Submit&quot;>
</form>
</body>
</html>
