noVNC (HTML5 VNC client) has some routines that can determine:

  • the actual position of a DOM element on a page: getPosition
  • the offset within that DOM element where a mouse click happened: getEventPosition

They should be fairly cross-browser.

You can use those as reference and that might help with your issue: http://github.com/kanaka/noVNC/blob/master/include/util.js#L121

Disclaimer: I made noVNC.
