Re: Search method or RegExp?

When testing with regex, use test(),

if (/(\S+@\S+\.\S+)/.test(sEmail)) {

better:

if (/^\S+@\S+\.\S{2,}$/.test(sEmail)) {

Why not use the last one?

return /^\S+@\S+\.\S\S+$/.test(sEmail);

Thanks all ... I looked over all the helpful suggestions, and have it
down to a simple one-liner. Evertjan, the last one you posted right
above didn't seem to like an address such as a@xxx

A boolean return value which the "test" method returns does seem more
intuitive than a check against -1. I'm guessing from the examples
everyone posted that using the "test" or even the "search" methods are
not any less supported by browsers than the RegExp object which I
don't recall anyone including in their examples. At any rate, I'm
going with the following validation test:

function checkEmail(sEmail) {
return (/(\S+@\S+\.\S+)/.test(sEmail));
}

Thanks all,
Ben
