JSON RedirecttoAction [英] JSON RedirecttoAction

问题描述

我试图从一个视图更改表中的值，然后使用Flash FSCommand和Json使用以下代码重定向到另一个视图:

I am trying to change a value in a table from one view, and then redirect to another view using Flash FSCommand and Json, using the following code:

        if (command == "nameClip") {
            var url = '<%= Url.Action("Index", "Home") %>';
            var clip = [args];
            try {
                $.post(url, { MovieName: clip }, function(data) {
                    ;
                }, 'json');
            }
            finally {
                // window.location.href = "/Demo/SWF";
            }
        }

在控制器中:

    [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult Index(SWF movietoplay)
    {

            var oldmovie = (from c in db.SWFs
                            where c.ID == "1"
                            select c).FirstOrDefault();

            var data = Request.Form["MovieName"].ToString();
            oldmovie.SWFName = data;
            db.SubmitChanges();
            return RedirectToAction("Show");
     }

除重定向外，其他所有方法都正常！

All works well except Redirect!!

推荐答案

您需要在AJAX成功回调中执行重定向:

You need to perform the redirect inside the AJAX success callback:

$.post(url, { MovieName: clip }, function(data) {
    window.location.href = '/home/show';
}, 'json');

无法在服务器端执行重定向，因为您正在使用AJAX调用此操作.

The redirect cannot be performed server side as you are calling this action with AJAX.

还要在AJAX调用中指出您希望服务器端提供JSON，但您发送的重定向不一致.您可以修改控制器操作，以简单地返回客户端需要使用JSON重定向到的网址:

Also you indicate in your AJAX call that you are expecting JSON from the server side but you are sending a redirect which is not consistent. You could modify the controller action to simply return the url that the client needs to redirect to using JSON:

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Index(SWF movietoplay)
{
    ...
    return Json(new { redirectTo = Url.Action("show") });
}

然后:

$.post(url, { MovieName: clip }, function(data) {
    window.location.href = data.redirectTo;
}, 'json');
