title: Reading web.config value through javascript
body: <p>I have web.config with the given value:</p>
  
  <pre><code>&lt;appSettings&gt;
          &lt;add key="vDirectory" value="fr" /&gt;
          &lt;add key="BookingSummaryPage" value="/pli/forms/BookingSummary.aspx" /&gt;
  &lt;/appSettings&gt;
  </code></pre>
  
  <p>Now I want to read the value of "vDirectory" through java script.</p>
  
  <p>I am using below code:</p>
  
  <pre><code>&lt;script language="javascript" type="text/javascript"&gt;
  
  function test()
  {
  var t='&lt;%=ConfigurationManager.AppSettings("vDirectory").ToString() %&gt;'
  alert(t);
  }
  &lt;/script&gt;
  
  &lt;input type="button" value="Click Me" onclick="test();" /&gt;
  </code></pre>
  
  <p>The error generated is:</p>
  
  <pre><code>Error 'System.Configuration.ConfigurationManager.AppSettings' is a 'property' but is used like a 'method' 
  </code></pre>
