Makes no sense at all. You have no access to "JS code", it is called by a browser. This code cannot live without HTML using it...

Please see my comments to the question, which is at least not clear. The idea to call JavaScript code of the HTML page from outside of the browser simply makes no sense.

Basically, you should do it all in your code, the same thing as the browser does, including authentication. You can use the class System.Net.HttpWebRequest:
http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.aspx[^],
http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.credentials.aspx[^].

Please see my past answers:
get specific data from web page[^],
How to get the data from another site[^].

You can find many code samples with authentication, such as:
http://stackoverflow.com/questions/1076015/handling-authentication-with-httpwebrequest-net[^],
HttpWebRequest Credential Authentication[^].

You can find a lot more: http://www.codeproject.com/search.aspx?q=%28HttpWebRequest+OR+HttpRequest%29+authentication&doctypeid=5[^].
