I needed a quick and easy way to check for the basics of an email address.

Does it contain “@” and “.” symbols.

This is by no meals a foolproof method, so don’t use it for anything big, but if you want to just do a quick test then here you go:

var email:String = "[email protected]";

if (email.indexOf("@")!=-1 && email.indexOf(".")!=-1) trace("false");
else trace ("true");
