[jQuery] change filedname from ID in jquery validation plugin

[bookme]

Hi, I am using Jquery plugin for client side validation. But due to a
filedname I am facing a problem.

Example
var validator = $("#UserSignupForm").validate({
                rules: {
                        data[User][username]: {
                                required: true,
                                minlength: 2,
                                remote: "users.php"
                        }

});

HTML :<input id="id_username1" name="data[User][username]" type="text"
value="" maxlength="50" />
