window.open() on a multi-monitor/dual-monitor system - where does window pop up?

Question

When using javascript window.open() on a multi-monitor system, how do you control which monitor, or where in the display space the popup opens? It seems out of control to me

Answer 1

window.screenX will give the position of the current monitor screen.

suppose monitor width is 1360

for monitor 1 window.screenX = 0;

for monitor 2 window.screenX = 1360;

so by adding left position with window.screenX, popup open in expected position.

function openWindow() {

    var width = 650;
    var left = 200;

    left += window.screenX;

    window.open(thePage,'windowName','resizable=1,scrollbars=1,fullscreen=0,height=200,width=' + width + '  , left=' + left + ', toolbar=0, menubar=0,status=1');    
    return 0;

}
