JS back button clicked

Question

I have some code which show popup when submit button clicked

$(document).ready(function() {
  ....
  @if (TempData.ContainsKey("TripUpdateSuccess"))
    {
        @:alertify.set({ delay: 3000 });
        @:alertify.success("Transport " + @(Model.BookingID) + " has been updated.");
        TempData.Remove("TripUpdateSuccess");
    }
}

When user clicked save, submit occurs and this popup shows (alertify.js) Then user hits back button, and this popup shows again. Seems back button restores state of TempData object in ASP.NET MVC.

My task is not to show this popup when back button pressed. How this can be done ?

Forgot to say, submit redirects to this page, so this is why back button points to this page.

[HttpPost]
public ActionResult TripUpdate(TripUpdateModel model)
{
   ....
   // pseudo code
   if (ok)
      TempData["TripUpdateSuccess"] = true;
   else if (TempData.ContainsKey("TripUpdateSuccess"))
                    TempData.Remove("TripUpdateSuccess");

}

At what point are you populating TempData["TripUpdateSuccess"]? — Nick Olsen, Mar 12 '14 at 13:21
Dump TempData before Post for debugging and that will answer your question. — Botonomous, Mar 12 '14 at 13:22
Updated message. TempData["TripUpdateSuccess"] is set in controller's action if eveything ok, in last line. if not ok i remove "TripUpdateSuccess" from TempData in same contoller's action. — user3328720, Mar 12 '14 at 13:24
I assume the population of TempData["TripUpdateSuccess"] happens in the controller. Can you show that code as well? — Nick Olsen, Mar 12 '14 at 13:26
And when you put a break point in the controller when you click the Back button, is "oK" true? Or is the back button going to the Get method? — Nick Olsen, Mar 12 '14 at 13:30
Not sure how its going, but action method not called when back button clicked — user3328720, Mar 12 '14 at 13:36
Take a look at the answer I posted. I think you are seeing the problem is due to a cached page. — Nick Olsen, Mar 12 '14 at 21:20

What's the problem? Do you need to hide popup when user hits back button?

yes, if i can detect in js that page loaded by back button - this will solve my problem – user3328720 Mar 12 '14 at 13:29
maybe you need reload your page on backbutton using location.reload(); or just hide popup using jquery method hid(); – user3127896 Mar 12 '14 at 13:35

Based on your comment:

"Not sure how its going, but action method not called when back button clicked"

It sounds like you are getting a cached version of the page when you click the back button instead of it actually doing a full round trip to the database. Essentially you need to disable the page from being cached by the browser so you get a full round trip.

Take a look at this thread: Back button not requesting asp.net mvc get method
