ASP.NET - accessing ViewBag in a View

Question

I have a one page that uses Javascript to load several PartialViews. I am trying to access ViewBag in some Javascript but am having problems.

MyView:

<div> <script> var test = @ViewBag.test; alert(test); </script> </div>

The controller which handles this view:

public PartialViewResult MyView() { ViewBag.test = "test"; return PartialView(); }

When I run it, the Javascript alert does not appear. I get a "Conditional compilation is turned off" highlight under the View's calling of ViewBag.

When your view is rendered, this is what is produced:

var test = test;

..that is obviously not valid javascript.

You need to enclose it in quotes:

var test = "@ViewBag.test";

Which produces:

var test = "test";

..valid Javascript.
