Get window locations across browsers

IE, Safari, Opera, and chrome all provide screenleft and screentop properties that indicate the position of the window relative to the left and top of the screen, respectively.

Firefox, Safari, and Chrome provide the same window information in ScreenX and ScreenY.

Opera supports ScreenX and ScreenY properties, but with Screenleft and screentop properties do not correspond, so do not use in opera ScreenX and ScreenY.

Use the following code to get the window position across browsers:

1 var leftpos = (typeof Window.screenleft = = "Number")?  2var topolpos = (typeof Window.screentop = = "Number")? Window.screentop: Window.screeny;
