javascript - Get browser window width including scrollbar

Question

I tried to get browser window width with $(window).width();. On IE 10, it does return the full browser width, include the scroll bar. However, on Firefox and Chrome, both return the value without the scroll bar.

How can I get the browser width include with the scroll bar together? Because I need the detected width to be exactly same as CSS.

Thanks.

The first answer was close, but upon further inspection it is a bit more complicated. The body.clientWidth is the width excluding the scrollbars. The window.outerWidth is the width including the scrollbars and other window elements like the window border. The window.innerWidth is the actual width of the window, including scrollbars, but not including the window border.
