javascript - Accessing ConfigurationManager.AppSettings in Java script -

i had javascript code in aspx file

page.aspx

<asp:content id="content1" contentplaceholderid="head" runat="server">  ----some code----  added after suggestion satpal  <script type="text/javascript"> var gaaccountid = '<%=configurationmanager.appsettings["gaaccountid"]%>'; </script> </asp:content> <asp:content id="content2" contentplaceholderid="maincontent" runat="server"> <%--<script type="text/javascript">         debugger;         var _gaq = _gaq || [];         _gaq.push(['_setaccount', '<%=configurationmanager.appsettings["gaaccountid"]%>']);         _gaq.push(['_setdomainname', 'auto']);         _gaq.push(['_setallowlinker', true]);         _gaq.push(['_trackpageview', '/register']);         _gaq.push(['_trackpageloadtime']);          (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>--%> </asp:content> 

now moved code seprate .js file , included reference in javascript file.now not able access it.it coming "'<%=configurationmanager.appsettings["gaaccountid"]%>']"

how value it.

<%=configurationmanager.appsettings["gaaccountid"]%> work when using in aspx file. not evaluated when using in external js file.

you can decalre variable in aspx page

<script type="text/javascript">     var gaaccountid = '<%=configurationmanager.appsettings["gaaccountid"]%>'; </script> 

use gaaccountid variable in js file
