当你请求AJAX调用，你应该使用重定向其响应

As you requesting AJAX call, you should redirect using its response

修改您的控制器与登陆网址返回JSONResult：

Modify your controller to return JSONResult with landing url:

public ActionResult SetEnddateRemarkToYesterday(int remarkID) {
    //Some logic to persist the change to DB.
    var redirectUrl = new UrlHelper(Request.RequestContext).Action("Index", "Controller");
        return Json(new { Url = redirectUrl });
}

JS调用：

$.post("Home/SetEnddateRemarkToYesterday", { remarkID: remarkID },  function (result) {
    window.location.href = result.Url
});
