Convert pixels to mouse position in browser

I capture the current mouse position in javascript by getting the x and y pixels. I am trying to then call an ASP.NET method with PageMethods and pass the coordinates. I believe the mouse_event is using a different coordinate system. How do I convert from pixels in a browser to the coordinates that the mouse_event is expecting? In my C# code I am doing the following:
 
        [System.Runtime.InteropServices.DllImport("user32.dll")]
        public static extern void mouse_event(int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo);

        public const int MOUSEEVENTF_LEFTDOWN = 0x02;
        public const int MOUSEEVENTF_LEFTUP = 0x04;
        public const int MOUSEEVENTF_RIGHTDOWN = 0x08;
        public const int MOUSEEVENTF_RIGHTUP = 0x10;

        [System.Web.Services.WebMethod]
        public static void MouseClick(int x, int y)
        {
            mouse_event(MOUSEEVENTF_LEFTDOWN, x, y, 0, 0);
            mouse_event(MOUSEEVENTF_LEFTUP, x, y, 0, 0);
        }

Sorry, I have not updated this earlier. What I ended up doing is..
function mouseClick(e) 
{
   var element = document.elementFromPoint(e.clientX, e.clientY);
   var evt = document.createEvent("MouseEvents");
   evt.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);
   element.dispatchEvent(evt);
}
