With JavaScript I want to take a input 1st validate that the email is valid (I solved for this) 2nd, validate that the email address came from yahoo.com
Anyone know of a Regex that will deliver the domain?

What about this?
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 3.2//EN">
<html>
<head>
<script type="text/javascript">
var okd = ['yahoo.com'] // Valid domains...
var emailRE = /^[a-zA-Z0-9._+-]+@([a-zA-Z0-9.-]+\.[a-zA-Z]{2,4})$/
function ckEmail(tst)
{
var aLst = emailRE.exec(tst)
if (!aLst) return 'A valid e-mail address is requred';
var sLst = aLst[1].toLowerCase()
for (var i = 0; i < okd.length; i++) {
if (sLst == okd[i]) {
return true
}
}
return aLst[1];
}
var ckValid = ckEmail(prompt('Enter your email address:'))
if (ckValid === true) {
alert(ckValid) // placeholder for process validated
} else {
alert(ckValid) // placeholder for show error message
}
</script>
<title></title>
</head>
<body>
</body>
</html>

A:
I don't think you need to use regex for this. You can use indexOf().
var s = emailAddress.indexOf("@yahoo.com");
if (s != -1) //this will be true if the address contains yahoo.com
To make sure you are searching the domain (in case someone's email is @[email protected]) you can split the address at the @ symbol and then again split the period. Then you can check if for 'yahoo' and 'com'.

Hmm. Are you sure that's valid JS? It's erroring

@nobosh that's because there is no statement after the `if`. styfle has shown you how to test if yahoo.com is in the string - you supply what happens after that.

A:
/@yahoo.com\s*$/.test(mystring)
is true if the string ends in @yahoo.com (plus optional whitespace).

A:
var rx = /^([\w\.]+)@([\w\.]+)$/;
var match = rx.exec("[email protected]");
if(match[1] == "yahoo.com"){
do something
}
second capturing group will contain the domain.

A:
To check for a particular domain (yahoo.com):
/^[^@\s][email protected]$/i.test(email)
// returns true if it matches
To extract the domain part and check it later:
x = email.match(/^[^@\s]+@([^@\s])+$/)
// x[0] contains the domain name

A:
>>> String('[email protected]').replace(/^[^@]*@/, '')
'yahoo.com'
