Hi

If your javascript is in the page you can use:

var globalResource = '<%= Resources.YourClass.YourResourceKey %>';

 to access the Global Resources (/App_GlobalResources). Or

var localResource = '<%= GetLocalResourceObject("LocalResourceKey").ToString() %>';

 to access the Local resources (/App_LocalResources relative to the page position).

You could also look at this tutorials.
