How to toggle the visibility of a script tag?

Question

How do I toggle the visiblity of a

<script>

tag in the markup? Have the following javascript code in my master page:

<script  type="text/javascript">
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
            document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script type="text/javascript">
  try {
   var pageTracker = _gat._getTracker("UA-108xxxx-2");
   pageTracker._trackPageview();
  } catch (err) { }
</script>
</body>

What is the best approach to serverside block this script from being rendered, if I want it to (like running in debug mode)

Answer 1

Put it inside a server-side if block.

For example:

<% if (!Request.IsLocal) { %>
<script  type="text/javascript">
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
            document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script type="text/javascript">
  try {
   var pageTracker = _gat._getTracker("UA-108xxxx-2");
   pageTracker._trackPageview();
  } catch (err) { }
</script>
<% } %>

Answer 2

Try this:

<asp:PlaceHolder id="PHScripts" runat="server">
  <script  type="text/javascript">
    var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
    document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
  </script>
  <script type="text/javascript">
    try {
     var pageTracker = _gat._getTracker("UA-108xxxx-2");
     pageTracker._trackPageview();
    } catch (err) { }
  </script>
</asp:PlaceHolder>

In your page:

PHScripts.Visible = !IsDebugMode;

For settings, I use a static class called AppSettings, and have a simple property like this beside the rest to determine if it's a debug build:

public static bool IsDebugMode
{
  get
  {
#if DEBUG
  return true;
#else
  return false;
#endif
  }
}

Then anywhere in the app:

AppSettings.IsDebugMode;
