validate email domain in object string

[surferj]

Hello,
I am trying to validate the suffix of an email address for a string entered into a form to ensure it contains the correct domain. Some of the code i am currently using looks like this for blank entries

if email="" then
response.redire ct "STS_form.asp?m sg=Please enter your EMAIL!" & querystr
end if

but i want to make sure that the email string contains the text "@wellsfargo.co m" and if not then redirect back to the form page.

So if i were to enter "abc@yahoo. com" i would be redirected back to the form to enter a valid email address. If i entered "abc@wellsfargo .com" then the process would continue to the next if statement.

I have tried to use the search and match statements with no avail. please help!

If you need to see more of my code, please let me know.

Thanks,

use regular expression.

var domain_pattern = /@wellsfargo.com$/;
var email_id = 'your email id';
alert(domain_pattern.test(email_id));

You can also do it by using "String.indexOf ". Actually there should be a function like "String.endsWit h" and "String.startsW ith".
Here you can write own "String.endsWit h" function like ..

String.prototype.endsWith = function(str){
 return this.indexOf(str)==this.length-str.length;
}
