Bootstrap 3 + Chosen + jquery validate loses forma

问题:

I have the code below http://jsfiddle.net/emamut/CBjmj/4/

$.validator.setDefaults({ ignore: ":hidden:not(select)" });
$('form').validate({
    highlight: function(element) {
        $(element).closest('.form-group').addClass('has-error');
    },
    unhighlight: function(element) {
        $(element).closest('.form-group').removeClass('has-error');
    },
    errorElement: 'span',
    errorClass: 'help-block',
    errorPlacement: function(error, element) {
        if(element.parent('.input-group').length) {
            error.insertAfter(element.parent());
        } else {
            error.insertAfter(element);
        }
    }
});

but when select validate the formatting is lost and returns the normal format of Chosen

In the errorPlacement option, when you use insertAfter it inserts the error message between the select element and the div.chosen-container. This fouls up the CSS used for the chosen widget. For example, if you use insertBefore, the problem goes away:

$.validator.setDefaults({ ignore: ":hidden:not(select)" });
    $('form').validate({
        highlight: function(element) {
            $(element).closest('.form-group').addClass('has-error');
    },
    unhighlight: function(element) {
        $(element).closest('.form-group').removeClass('has-error');
    },
    errorElement: 'span',
    errorClass: 'help-block',
    errorPlacement: function(error, element) {
        if(element.parent('.input-group').length) {
            error.insertAfter(element.parent());
        } else if (element.is('select')) {
            error.insertBefore(element);
        } else
        {
            error.insertAfter(element);
        }
    }
});

If what you want is to add the error message bellow the chosen, you always can add it after adding this clause to the errorPlacement:

else if (element.is('select')) {
   error.insertAfter(element.siblings(".chosen-container"));
}
