Hey, the problem seems to be with the {2,63} bit, so I've rewritten
your code (again), it's not as strict as before but it's a lot faster
now because it tests string length rather than regex lengths:
$(document).ready(function(){
var reg = /^[a-z0-9]+[a-z0-9\-\.]*\.[a-z]{2,4}$/i;
$('input#domain').keyup(function(){
var domain = $(this).val();
if (reg.test(domain) && domain.length >= 5 && domain.length <= 68) {
$("#ok").html("Correct format...");
} else {
$("#ok").html("Wrong format...");
}
});
});
