ASP.NET MVC 5应用程序-如何在ajax发布后重定向到URL？

Question

I am trying to redirect the user to a page after the ajax post is successful. The session variable does get changed, but it never redirects afterwards.

Controller:

[HttpPost]
public ActionResult SelectFacility(string Facility)
{
    System.Web.HttpContext.Current.Session["Facility"] = Facility;
    return Json(new { redirectToUrl = Url.Action("Index", "Incident") });
}

Javascript

$("#Facility").on("change", function () {
        var fac = $(this).find("option:selected").text();
        /*
        $.post("/Incident/SelectFacility", {
            Facility: fac
        });
        window.location = result.redirectUrl;*/

        $.ajax({
            url: '@Url.Action("SelectFacility","Incident")',
            type: 'POST',
            //contentType: 'application/json', not needed
            //dataType: 'jsonp', jsonp is for sending to a site other than the current one
            data: {
                Facility: fac
            },
            success: function (result) {
                if (result == true) {
                    window.location = result.redirectUrl;
                }
            }
        });
    });

Answer 1

Firstly result will hold an object, so comparing it to true is rather odd (although will actually work here due to type coercion).

Secondly, and the main issue with your logic, is that you're checking the redirectUrl property of the response, but the correct name is redirectToUrl .

success: function(result) {
  window.location = result.redirectToUrl;
}

However, it's worth noting that in this situation the AJAX request is completely redundant as you're redirecting the page immediately after it completes anyway.

I assume in youn controller you have action, after that use location.href to redirect where you action is located.

$(document).on('click', '.functionName', function() {
  swal({
    title: "Are you sure?",
    type: "info",
    showCancelButton: true,
    confirmButtonColor: "#2196F3",
    confirmButtonText: "Yes, assign it!",
    closeOnConfirm: false,
    showLoaderOnConfirm: true,
  }, function() {
    $.ajax({
      type: "post",
      url: "User/Create",
      ajaxasync: true,
      success: function() {
        swal("Assigned!", "User has been created!", "success");
        location.href = "/User/Create";
      },
      error: function(data) {
        swal("Oops", "Something went wrong!", "error");
      }
    });

you can simply use in your MVC view in ajax success-

 success:function() { window.localtion.href="@Url.Action("Index","Home")"; }
