If you create a new ASp.NET Web Application project in Microsoft Visual Studio 2010 and want to use the Sys.Debug function in an JavaScript function, you get the error ‘Sys’ is undefined. To solve this error, just drag and drop a ASP .NET scriptmanager from the toolbox on you’re master page, just below the form tag.
Example
<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site.master.cs" Inherits="Rvl.Demo.TrainingWebApplication.SiteMaster" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"> <head runat="server"> <title></title> <link href="~/Styles/Site.css" rel="stylesheet" type="text/css" /> <asp:ContentPlaceHolder ID="HeadContent" runat="server"> </asp:ContentPlaceHolder> </head> <body> <form runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <div class="page"> <div class="header"> <div class="title"> <h1> My ASP.NET Application </h1> </div> <div class="loginDisplay"> <asp:LoginView ID="HeadLoginView" runat="server" EnableViewState="false"> <AnonymousTemplate> [ <a href="~/Account/Login.aspx" ID="HeadLoginStatus" runat="server">Log In</a> ] </AnonymousTemplate> <LoggedInTemplate> Welcome <span class="bold"><asp:LoginName ID="HeadLoginName" runat="server" /></span>! [ <asp:LoginStatus ID="HeadLoginStatus" runat="server" LogoutAction="Redirect" LogoutText="Log Out" LogoutPageUrl="~/"/> ] </LoggedInTemplate> </asp:LoginView> </div> <div class="clear hideSkiplink"> <asp:Menu ID="NavigationMenu" runat="server" CssClass="menu" EnableViewState="false" IncludeStyleBlock="false" Orientation="Horizontal"> <Items> <asp:MenuItem NavigateUrl="~/Default.aspx" Text="Home"/> <asp:MenuItem NavigateUrl="~/About.aspx" Text="About"/> </Items> </asp:Menu> </div> </div> <div class="main"> <asp:ContentPlaceHolder ID="MainContent" runat="server"/> </div> <div class="clear"> </div> </div> <div class="footer"> </div> </form> </body> </html>
The Sys.Debug will now work:
