How to read session values ​​using jQuery

Question

I am using C # and jQuery.

I have the code below where I set the session variable using C # code.

if (!string.IsNullOrEmpty(results))
{
    string[] array = results.Split(',');
    string firstName = array[0];
    string lastName = array[1];
    string activeCardNo = array[2];
    string memberShipTier = array[3];
    string accessToken = array[4];

    Session["skyFirstName"] = firstName.ToString();
    Session["skyLastName"] = lastName.ToString();
    Session["skyActiveCardNo"] = activeCardNo.ToString();
    Session["skyMemberShipTier"] = memberShipTier.ToString();
    Session["boolSignOn"] = "true";
    Response.Redirect(fromPage);
    Response.End();
}

Now I want to read these values ​​( Session["skyFirstName"]) using jQuery so that I can set in my elements. Please suggest.

Answer 4

jQuery is javascript, so in order to have these variables you need to print the html code (at least one script tag) where you set the reading session variables from C # as a javascript variable.

An alternative could be to use an ajax request to get session variables from a script server.
