[jQuery] jQuery validation - Numbers not allowed
I have this code:
$(document).ready(function() {
// validate signup form on keyup and submit
var validator = $("#signupform").validate({
rules: {
firstname: "required",
lastname: "required",
username: {
required: true,
minlength: 2,
remote: "users.php"
}
}
});
});
How do I set the validation that no number are allowed in the
firstname text box????
