How can I check from a window whether the opener window has been closed?

Window objects have a boolean
  closed
property you can check so access the opener window
  window.opener
and check the property
  if (window.opener.closed)
    // do stuff when opener closed perhaps
    // window.close()
  else
    // do stuff when opener is still open
