JavaScript Regular Expression Email Validation

I've been using this function for a while. it returns a boolean value.

// Validates email address of course.
function validEmail(e) {
    var filter = /^\s*[\w\-\+_]+(\.[\w\-\+_]+)*\@[\w\-\+_]+\.[\w\-\+_]+(\.[\w\-\+_]+)*\s*$/;
    return String(e).search (filter) != -1;
}

If you define your regular expression as a string then all backslashes need to be escaped, so instead of '\w' you should have '\\w'.

Alternatively, define it as a regular expression:

var pattern = /^\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,3}$/;

BTW, please don't validate email addresses on the client-side. Your regular expression is way too simple to pass for a solid implementation anyway.

See the real thing here: http://www.ex-parrot.com/~pdw/Mail-RFC822-Address.html

this is the one i am using on my page.

/^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,6}$/
