Exploring the world of value tracking with JavaScript

on page A

 test.Controls.Add(GetButton(thisReader["session_name"].ToString(), "Join Session"));

Response.Redirect("EnterSession.aspx?session=" + e.CommandArgument.ToString());

on page B

 _gaq.push(['pageTrackerTime._trackEvent', 'category', 'action', document.location.href, roundleaveSiteEnd]);

when a user clicks a button on page A , they will be directed to page B where I used document.location.href to track the current URL. Now, I want to also track session_name from page A using JavaScript.

How can I achieve this?

The original code looked like this:

SqlCommand thisCommand = thisConnection.CreateCommand();
                thisCommand.CommandText = "SELECT * FROM Tmyapp_Session;";
                SqlDataReader thisReader = thisCommand.ExecuteReader();

                while (thisReader.Read())
                {
                    test.Controls.Add(GetLabel(thisReader["session_id"].ToString(), thisReader["session_name"].ToString()));
                    string[] compare = secondResult.Split(';');
                    foreach (string word in compare)
                    {
                        if (word == thisReader["session_id"].ToString())

                        {
                            test.Controls.Add(GetButton(thisReader["session_id"].ToString(), "Join Session"));

I had to modify the last code to:

test.Controls.Add(GetButton(thisReader["session_name"].ToString(), "Join Session"));

session_id was changed to session_name

since I wanted the URL to contain the value of the session_name

        var visits = getCookie("visits");
        document.writeln(" You have visited " +
          visits + " time(s) before.");
        setCookie("visits",parseInt(visits)+1);
      }
      else {                  // new visitor
        var username = prompt("What is your name ?","");
        if (username != null) {
          setCookie("username",username);
          setCookie("visits",1);
          document.writeln("Thank you. Please refresh this page.");
        }
      }
    </SCRIPT>
  </BODY>
</HTML>

Hopefully, this solution solves the issue!

It appears that extracting the session_name from the querystring is the solution you're looking for. For more information, take a look at this helpful post here, which provides some useful methods for achieving this.

There are two potential approaches to achieve your goal. One option is to include another querystring parameter:

/url.aspx?session_name=[session_name]&session_id=[session_id]

Alternatively, you could store the session_id in a session variable:

session["session_id"] = session_id;
