1. In Page Load event store the config value in hidden fields using Config Manager.
2. Retire from hidden fields using JQuery.
3. JQuery function function GetWebConfigVal(){ var hiddenFildsVal=$("#hiddenFiledId").val(); alert(hiddenFildsVal); }

In the web.config file inside the write this code in the C# code file write the code for calling the JavaScript code

dispay()
{
hdn.Value = ConfigurationManager.AppSettings["insert"];
ScriptManager.RegisterStartupScript(this.Page, Page.GetType(), "text", 
"msg()", true);
}

<script>
    function msg()
    {
        alert('<%= hdn.Value%>');
    }
</script>

this will display the message that is stored in appsettings of web.config file using the alert function of the JavaScript.
