Jquery 需要来自组的错误放置

Question

我正在使用以下 js 并尝试将其与错误放置相结合。基本上，我只是尝试将错误消息打印到特定的 div.

我想我应该使用类似的东西：

errorPlacement: function(error, element) {
    if (element.attr("class") == "days_group" )
        error.insertAfter("#special_place");        
    else
        error.insertAfter(element);
}

但我不确定这是否有效或将代码放在以下位置：

这是link到jsfiddle（您需要转到第三页）

$(".next").click(function(){
                var form = $("#reg_form");
                form.validate({
                    errorElement: 'span',
                    errorClass: 'help-block',
                    highlight: function(element, errorClass, validClass) {
                        $(element).closest('.form-group').addClass("has-error");
                    },
                    unhighlight: function(element, errorClass, validClass) {
                        $(element).closest('.form-group').removeClass("has-error");
                    },

                    groups: {

Answer 1

试试这个：

errorPlacement: function(error, element) {
    if (element.hasClass("days_group")) {
        error.insertAfter("#special_place");
    } else {
        error.insertAfter(element);
    }
}
