Passing any data from a partial view that is rendered with $.get() to ContentPage

I am trying to make my web application like a desktop application. I am also not using any _LayoutPage and @RenderBody().

I have a ContentPage as MasterPage and a tag named main. I am using ajax get method to render my views or partial views like this:

  $.get(url).done(function (result) {
            $("main").html(result);
        });

I managed to inject my script and css files with javascript functions.

And now I want to pass some specific datas without using javascript functions.

It can be via using ViewBag, I guess.

I want to pass that data from my partialView:

 ViewBag.BodyClass = "signup-page";

to my MainPage like this:

<body class="@ViewBag.BodyClass">

How can I do that?

Solution

I wrote that code on my partialView. It adds a class at ContentPage's body tag

$("body").addClass("signup-page");
