I have web.config with the given value:

<appSettings>

        <add key=vDirectory value=fr />

        <add key=BookingSummaryPage value=/pli/forms/BookingSummary.aspx />

</appSettings>

Now I want to read the value of vDirectory through java script.

I am using below code:

<script language=javascript type=text/javascript>



function test()

{

var t='<%=ConfigurationManager.AppSettings(vDirectory).ToString() %>'

alert(t);

}

</script>



<input type=button value=Click Me onclick=test(); />

The error generated is:

Error 'System.Configuration.ConfigurationManager.AppSettings' is a 'property' but is used like a 'method'
