validate email address from string

handy for a simple email verification in a form submit

var emailfield = $("#emailfield").val();
var atpos = emailfield.indexOf("@");
var dotpos = emailfield.lastIndexOf(".");
if (atpos<1 || dotpos=emailfield.length) {
    alert("Not a valid e-mail address");
    return false;
}
