Parameters

  • deltaX is the amount of pixels to move the window horizontally.
  • deltaY is the amount of pixels to move the window vertically.

Notes

You can use negative numbers as parameters for this function. This function makes a relative move while window.moveTo makes an absolute move.

Since Firefox 7, it's no longer possible for a web site to move a window in a browser, according to the following rules:

  1. You can't move a window or tab that wasn’t created by window.open.
  2. You can't move a window or tab when it’s in a window with more than one tab.
