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.

Hi, Vignesh Mani

Hi Just use in jquery like '@TempData["Ex"]' instead of raw data. Just try this. otherwise inform me i will try another method.

Thanks Vignesh Mani,

But Data param in success function returning view. so i can not do this. actually based on Tempdata["Ex"] value i am trying to identifying which view is returning in data param and based on that i am modifinng DOM.

Hi Friend try below mentioned method. Please modify in your code what i wrote in green color

public ActionResult Index()
{
return Json(new { status = "Success", message = "Success" });
}

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.status == "Success")
{
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..!!");
}
});

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.

use this if ('TempData["Ex"]' == true)
