How to redirect to a controller action from a JSONResult method in ASP.NET MVC?
提问by ACP
I am fetching records for a user based on his UserIdas a JsonResult...
我正在根据他UserId的 JsonResult为用户获取记录...
public JsonResult GetClients(int currentPage, int pageSize)
{
if (Session["UserId"] != "")
{
var clients = clirep.FindAllClients().AsQueryable();
var count = clients.Count();
var results = new PagedList<ClientBO>(clients, currentPage - 1, pageSize);
var genericResult = new { Count = count, Results = results };
return Json(genericResult);
}
else
{
//return RedirectToAction("Index","Home");
}
}

This will depend on how you are invoking this controller action. As you are using JSON I suppose that you are calling it in AJAX. If this is the case you cannot redirect from the controller action. You will need to do this in the successcallback of the AJAX script. One way to achieve it is the following:
这将取决于您如何调用此控制器操作。当您使用 JSON 时，我想您是在 AJAX 中调用它的。如果是这种情况，您将无法从控制器操作重定向。您需要success在 AJAX 脚本的回调中执行此操作。实现它的一种方法如下：
return Json(new
{
redirectUrl = Url.Action("Index", "Home"),
isRedirect = true
});
And in the success callback:
在成功回调中：
success: function(json) {
if (json.isRedirect) {
window.location.href = json.redirectUrl;
}
}
Remark: Make sure to include isRedirect = falsein the JSON in case you don't want to redirect which is the first case in your controller action.
备注：确保包含isRedirect = false在 JSON 中，以防您不想重定向，这是控制器操作中的第一种情况。

Adding to Darin Dimitrov's answer. For C#.NET MVC - If you want to redirect to a different page/controller and want to send an Object/Model to the new controller, You can do something like this.
添加到 Darin Dimitrov 的答案。对于 C#.NET MVC - 如果您想重定向到不同的页面/控制器并想将对象/模型发送到新控制器，您可以执行以下操作。
In the JsonResult Method (in the controller):
在 JsonResult 方法中（在控制器中）：
ErrorModel e = new ErrorModel();
e.ErrorTitle = "Error";
e.ErrorHeading = "Oops ! Something went wrong.";
e.ErrorMessage = "Unable to open Something";
return Json(new
{
redirectUrl = Url.Action("Index", "Home",e),
isRedirect = true
});
And in the success callback:
在成功回调中：
success: function(json) {
if (json.isRedirect) {
window.location.href = json.redirectUrl;
}
}
And if the new controller can accept the model/object like below.. you can pass the object to the new controller/page
如果新控制器可以接受如下所示的模型/对象..您可以将对象传递给新的控制器/页面
public ActionResult Index(ErrorModel e)
{
return View(e);
}
Hope this helps.
希望这可以帮助。

What to do you think about trying to call:
你怎么想尝试打电话：
return (new YourOtherController()).JSONResultAction();
instead of using redirects?
而不是使用重定向？

And if you work with areas ...
如果您与区域合作...
Controller:
控制器：
return Json(new
{
redirectUrl = Url.Action("Index", "/DisparadorProgSaude/", new { area = "AreaComum" }),
isRedirect = true
});
View:
看法：
success: function (json) {
if (json.isRedirect) {
window.location.href = json.redirectUrl;
}
},

No way to do this, the client is executing an AJAX script so will not be able to handle anything else.
没有办法做到这一点，客户端正在执行 AJAX 脚本，因此将无法处理其他任何事情。
I suggest you redirect in the client script based on the returned data in the callback function.
我建议您根据回调函数中返回的数据在客户端脚本中重定向。
