Using Web.config app data in Javascript/HTML

I am using this tutorial to use a variable from web.config file into .NET . Now I want to use the exact same variable in JavaScript but according to my research the WebConfigurationManager variable is not available in HTML , any clue on how to do that ?

thanks

EDIT :

I tried to implement the suggested code in that way (just to make sure that it gives me the output I want):

var myJsVar = '<%= ConfigurationSettings.AppSettings["MyConfigValue"] %>';
alert(myJsVar);

the value of myJsVar come up as 

<%= ConfigurationSettings.AppSettings["MyConfigValue"] %>

and when I do '<%= ConfigurationSettings.AppSettings["MyConfigValue"] %>'

and when I do alert(myJsVar.valueof()); instead I receive undefined as output

I also tried to use WebConfigurationManager instead of ConfigurationSettings and it goes through the same logic ...

You can render the value to the aspx page, as an assignment to a JavaScript variable:

var myJsVar = '<%= ConfigurationSettings.AppSettings["MyConfigValue"] %>';

So this way, myJsVar will be initialized with MyConfigValue. Hope this helps.

EDIT

If you are using Razor you should use this way

var myJsVar = '@System.Configuration.ConfigurationManager.AppSettings["MyConfigValue"]';

You just need to output the setting into the variable you want. Somewhere in your javascript you would put:

<script language="javascript">

    var mySetting = '<%=ConfigurationManager.AppSettings["mySetting"] %>';

</script>

Here the <%= is a Response.Write command that will output the string result to the markup rendered. From this point on the variable mySetting would be accessible to any components.
