Jquery Value match Regex [duplicate]
- Pass a string to RegExp or create a regex using the
//
syntax - Call
regex.test(string)
, notstring.test(regex)
So
jQuery(function () { $(".mail").keyup(function () { var VAL = this.value; var email = new RegExp('^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$'); if (email.test(VAL)) { alert('Great, you entered an E-Mail-address'); } });});
Change it to this:
var email = /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i;
This is a regular expression literal that is passed the i
flag which means to be case insensitive.
Keep in mind that email address validation is hard (there is a 4 or 5 page regular expression at the end of Mastering Regular Expressions demonstrating this) and your expression certainly will not capture all valid e-mail addresses.
