Question

我是Mvc jason的新手我有跟随ajax功能，该功能工作正常并将数据发送到服务器操作，服务器也返回成功或失败但问题是JSON数据显示在新页面中

{＆＃34;成功＆＃34;：真}

这是我的ajax功能

$('#save').click(function () {
    var CourseID = $('.form-control span1').val();
    var Type = $('.form-control span2').val();
    var id =@Model.UserId
         $.ajax({
             url: '@Url.Action("AdminUser/Edit")',
             type: 'POST',
             data: { id: '@Model.UserId', CourseID: CourseID, Type: Type },
             Success: function (response) {
                 if (response.Success) {
                     alert("done");
                 }
                 else {
                     alert("Errror");
                 }

             }
         });



});

这是我的控制器

      [HttpPost]
    public ActionResult Edit(int id, string CourseID, string type)
    {
        KBS_Virtual_TrainingEntities db = new KBS_Virtual_TrainingEntities();
        var sc = (from course in db.CourseSubscriptions.ToList()
                  where course.Cours.ID.ToString() == CourseID && course.SubscriptionsType.ID.ToString() == type
                  select course).SingleOrDefault();
        UserSubscription new_sub = new UserSubscription();

        CourseSubscription sub_course = (CourseSubscription)sc;
        if (sub_course != null)
        {

            new_sub.CourseSubscription = sub_course;
            new_sub.CourseSubscriptionID = sub_course.ID;
            new_sub.StartedDate = DateTime.Now;
            new_sub.UserID = id;
            db.UserSubscriptions.Add(new_sub);
            db.SaveChanges();


            return Json(new { Success = true });
        }

         return Json(new{Success = false});
    }

Answer 1

尝试将return Json(new { Success = true });更改为

return Json(new { });

如何触发false而不是默认设置为true？

Answer 2

试试这个：

$('#save').click(function () {
var CourseID = $('.form-control span1').val();
var Type = $('.form-control span2').val();
var id =@Model.UserId
     $.ajax({
         url: '@Url.Action("AdminUser/Edit")',
         type: 'POST',
         data: { id: '@Model.UserId', CourseID: CourseID, Type: Type },
         Success: function (response) {
             if (response.Success) {
                 alert("done");
             }
             else {
                 alert("Errror");
             }
             return false;
         }
     });

}）;

return false将停止页面的重定向添加脚本包〜/ bundles / jqueryval
