Does jQuery have a built in function to return the rootURL?
<p>I typically use the below function to return the root URL if I ever need this, but thought to ask if jQuery had a "one liner" way to do this ...</p>

<pre><code>function getRootURL()
        {
            var baseURL = location.href;
            var rootURL = baseURL.substring(0, baseURL.indexOf('/', 7));

            // if the root url is localhost, don't add the directory as cassani doesn't use it
            if (baseURL.indexOf('localhost') == -1)
            {
                return rootURL + "/AppName/";
            } else {
                return rootURL + "/";
            }
        }
</code></pre>
