Regular expression in JavaScript

Question

Hi boys:

I am trying to validate a TextEdit in order to contains a truly email address. I have a regular expression to do that, but it validates more than one address, and I just want to validate only one address, no more.

Here you are the expression I have:

/^[_a-z0-9-]+(.[_a-z0-9-]+)*@[a-z0-9-]+(.[a-z0-9-]+)*(.[a-z]{2,3})$/

It validates something like this:

[email protected], [email protected]

I need take the second email address out of the TextEdit.

So, How can I do that??

Note: I am sorry about my English.

Answer 1

Try this

/^([a-zA-Z0-9_.-])+@(([a-zA-Z0-9-])+.)+([a-zA-Z0-9]{2,4})+$/

Here is a great tutorial on Email Regex - including how to find emails in text.

It is important to understand how Regex works and not just copy and paste.
