Question

这个Q.是这个问题的继续first qestion我有一个表单需要重定向到表单上传的详细信息（就像在stackoverflow中一样），但显然是因为我正在使用Ajax，它防止它重定向，我试图添加我的Ajax重定向但我不断收到错误和错误的网址。它应该从http://localhost:1914/En/VoosUp/Create重定向到http://localhost:1914/En/events/Index/42（E.G. Id号码）我得到的结果是我在Js代码中得到的结果如何将其重定向到正确的URL（事件/索引/ Id）提前致谢 Js

function GetLocation() {
    var geocoder = new window.google.maps.Geocoder();

    var street = document.getElementById('txtAddress').value;
    var city = document.getElementById('txtCity').value;
    var address = city + street;
    console.log(address);
    var labelLat = document.getElementById('Latitude');
    var labellong = document.getElementById('longitude');

    geocoder.geocode({ 'address': address },
        function(results, status) {
            if (status == window.google.maps.GeocoderStatus.OK) {
                var latitude = results[0].geometry.location.lat();
                var longitude = results[0].geometry.location.lng();
                console.log("Latitude: " + latitude + "\nLongitude: " + longitude); //Ok.

                labelLat.value = latitude; //Ok.
                labellong.value = longitude;
                var form = $('#RestoForm')[0];
                var formData = new FormData(form);
                $.ajax({
                    url: 'Create',
                    type: 'POST',
                    contentType: false,
                    processData: false,
                    data: formData,
                    datatype: "html",
                    success: function(data) {
                        $('#RestoForm').html(data),
                            //   window.location.href = '@Url.Content:("~/Events/Index")' + "Id";
                            //= A potentially dangerous Request.Path value was detected from the client (:).
                            // En/VoosUp/@Url.Content:("~/Events/Index")Id
                            window.location.href = '@Url.Action("~/Events/Index")';
                        // =The resource cannot be found >
                        //En/VoosUp/@Url.Action("Events/Index 

                    }

                });

                error: function e(xhr, ajaxOptions, thrownError) {
                    alert(xhr.status);
                    alert(thrownError);
                }
            }
        });
};`

控制器：

 [Authorize]
    public ActionResult Create()
    {
        var viewModel = new LectureFormViewModel
        {
            Genres = _context.Genres.ToList(),

        };
        return View("Gigform", viewModel);
    }

    [Authorize, HttpPost]
    public ActionResult Create(LectureFormViewModel viewModel)
    {

        if (!ModelState.IsValid)
        {
            viewModel.Genres = _context.Genres.ToList();

            return View("Gigform", viewModel);
        }


        var lectureGig = new LectureGig
        {
           //Parameters
        };

        _context.LectureGigs.Add(lectureGig);
        _context.SaveChanges();

        // return this.RedirectToAction( "events", (c=>c.Index(lectureGig.Id));
        return RedirectToAction("index", "Events", new { id = lectureGig.Id });
    }

和目标

 public ActionResult Index(int id)
    {
        var lecturegig = _context.LectureGigs.Include(g => g.Artist)
           .Include(g => g.Genre)
           .SingleOrDefault(g => g.Id == id);
        if (lecturegig == null)
            return HttpNotFound();
        var viewmodel = new GigDetailViewModel { LectureGig = lecturegig };

        return View("index", viewmodel);
    }

Answer 1

如果您的JavaScript位于cshtml中，则应该这样做：

   var id = 1;
   var url = '@Url.Action("Index", "Events")';
   window.location.href = url + "/" + id;

根据你的描述，似乎你试图从一个不了解MVC助手的.js文件中调用它，所以你可以尝试这样的事情：

var id = 1; 

var getUrl = window.location;
var baseUrl = getUrl.protocol + "//" + getUrl.host + "/" + getUrl.pathname.split('/')[1];

window.location.href = baseUrl + '/Events/Index' + id;

要获得正确的ID修改您的操作以返回Id，例如

public JsonResult Create(LectureFormViewModel viewModel)
{
   return Json(new { Id=lectureGig.Id });
}

然后您可以在JavaScript中访问此ID，例如

 success: function(data) {
   var id = data.Id;
 }

Answer 2

如果它在cshtml文件中，您可以使用代码

window.location.href = '@Url.Action("Index", "Events")'+ "?id=1";

如果您在js文件中

window.location.href='/Events/Index?id=1'

window.location.href的脚本错误
