How to Read Tempdata, Viewbag to external JS file using ajax

Question

How to Read Tempdata, Viewbag in external JS file using ajax jquery method

 

  I have logon controller with method

 

public ActionResult Index()

{

      TempData["Ex"] = "True";

      return View();

}

 

i called a request by button's click event and click event code is in external js file as given 

 

var data = $('form').serialize();

$.ajax({

            url: "../RP/GetDetails", // RP is another controller

            dataType: 'html',

            t ype: "GET",

            data: data,

            contentType: "application/html; charset=utf-8",

            success: function (data)

            {

                     if ('@Html.Raw(TempData["Ex"])' == 'True') // Need to access tempdata value here

                           { 

                                  / / Perform some action

                           }

                     else

                           {

                                  // Else perform some other action

                           }

            },

            error: function (error)

               {

                        alert("Please Check Model..!!");

               }

   });

 

In this case, Method of report controller is called on button click event but if session is expire then automatically login controller is called and tempdata

value is set based on that tempdata value in external js file, action will be prosessing but i am unable to get  TempData["Ex"]  js file.

Hi TempData act as like string. If you store value that value also act as a string.

Thanks Shuvojit,

 

 

   But i have already tried this code. this is not working. If i write my button click ajax code to view and use to read temp data value as 

 

if('@Html.Raw(TempData["Ex"])'==true)

 

then this is working but when i put this code in external js this not working.
