Javascript – How to get JavaScript to open a popup window on the current monitor



  1. The user has two monitors.
  2. Their browser is open on the secondary monitor.
  3. They click a link in the browser which calls with a specific top and left window offset.
  4. The popup window always opens on their primary monitor.

Is there any way in JavaScript to get the popup window to open on the same monitor as the initial browser window (the opener)?

Best Solution

You can't specify the monitor, but you can specify the position of the popup window as being relative to the where the click caused the window to popup.

Use the getMouseXY() function to get values to pass as the left and top args to the method. (the left and top args only work with V3 and up browsers). docs:

function getMouseXY( e ) {
    if ( event.clientX ) { // Grab the x-y pos.s if browser is IE.
        CurrentLeft = event.clientX + document.body.scrollLeft;
        CurrentTop  = event.clientY + document.body.scrollTop;
    else {  // Grab the x-y pos.s if browser isn't IE.
        CurrentLeft = e.pageX;
        CurrentTop  = e.pageY;
    if ( CurrentLeft < 0 ) { CurrentLeft = 0; };
    if ( CurrentTop  < 0 ) { CurrentTop  = 0; };  

    return true;
