How do I give JavaScript variables data from ASP.NET variables?

Question

I have created a SCORM API for our LMS and right now I am using hard coded userID and courseID variables (variables that reference things in the database). I need to pass the real userID and courseID instead of using hard coded ones. I know the userID is stored in the session and the courseID is passed over from the launch page.

How do I get these into JavaScript so I can include them in my calls to the .ashx that handles the SCORM calls?

Probably best easiest to expose them as properties of your page (or master page if used on every page) and reference them via page directives.

 <script type="text/javascript">      var userID = '<%= UserID %>';      var courseID = '<%= CourseID %>';       .... more stuff....  </script> 

Then set the values on Page_Load (or in the Page_Load for the master page).

  public void Page_Load( object source, EventArgs e )   {          UserID = Session["userID"];         CourseID = Session["courseID"];         ...   }
