How to reliably get screen width WITH the scrollbar

Question

Is there a way to reliably tell a browser\'s viewport width that includes the scrollbar, but not the rest of browser window)?

None of the properties listed here tell

I figured out how to accurately get the viewport width WITH the scrollbar using some code from: http://andylangton.co.uk/blog/development/get-viewport-size-width-and-height-javascript

Put this inside your $(document).ready(function()

$(document).ready(function(){
    $(window).on("resize", function(){
      function viewport() {
          var e = window, a = 'inner';
          if (!('innerWidth' in window )) {
              a = 'client';
              e = document.documentElement || document.body;
          }
          return { width : e[ a+'Width' ] , height : e[ a+'Height' ] };
      }
    });
    // Get the correct window sizes with these declarations
    windowHeight = viewport().height;
    windowWidth = viewport().width;  
});

What it Does:

When your page is 'ready' or is resized, the function calculates the correct window height and width (including scrollbar).
