Google Analytics Razor Helper

I experimented today with the Razor helper syntax to consolidate generation of the Google Analytics tracking boilerplate (in ~/App_Code/Helpers.cshtml):

@helper GoogleAnalyticsTracker(string analyticsId) 
{
   if (!String.IsNullOrEmpty(analyticsId))
   {
   <script type="text/javascript">
            var _gaq = _gaq || [];
            _gaq.push(['_setAccount', '@analyticsId']);
            _gaq.push(['_trackPageview']);

            (function () {
                var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
                ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
                var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
            })();
    </script>
    }
}

which can then be used in your layout pages with:

@Helpers.GoogleAnalyticsTracker(Model.GoogleAnalyticsId)

It’s a bit unclear where this mechanism should fit between custom HtmlHelper extension methods and Razor partial views. I guess you’d be looking for functionality that’s less generic than an HtmlHelper extension – you can modify without recompiling, and it’s less simple to share between projects – and smaller/more generic than a partial.

The App_Code requirement for sharing between pages is not ideal, particularly as HtmlHelper extension methods aren’t available without workarounds. Hopefully the team get an update out in a reasonably timeframe.
