TypeHere.keyup(function (e) {
     switch (e.keyCode) {

            TypeHere.width(myInputLength * 6 + 15);
            //Check for email validation. //You can apply webservices for any type of validation.
            var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/;
            if (myInputText.length == 0) {
