为什么我不能重定向到索引？

Question

I cannot return anywhere after setting cookie, the cookie sets properly but after setting the cookie , it wont redirect anywhere .

Here is my code in view:

<a onclick="changeGuestCity(@city.LocationId)">
   <span class="font-400 opacity-70">@city.LocationTitle</span>
</a>

Here is the JavaScript's function:

<script>

        function changeGuestCity(id) {
            $.get("/Home/ChangeGuestCity/" + id);
        }

</script>

Here is my the function but doesn't redirect to Index or anywhere else:

 public IActionResult Index()
 {
     return View();
 }



 public IActionResult ChangeGuestCity(int? id)
 {

     if (id == null)
         return Redirect("/");

     CookieOptions cityCookie = new CookieOptions()
     {
         Expires = DateTime.Now.AddDays(30)
     };

     Response.Cookies.Append("city", id.ToString(), cityCookie);

     return Redirect("/");
 }

Answer 1

Try this code:

return Index();

Answer 2

Do you mean you want to redirect to some where when you click the tag?

You can't redirect from $.get(), here are two ways:

You can set the page you want to direct to in href:

<a href="controller/action" onclick="changeGuestCity(@city.LocationId)">

Or redirect in your javascript:

function changeGuestCity(id) {
        $.get("/Home/ChangeGuestCity/" + id);
        window.location.href = "controller/action";
    }
