10931 - Feature: onload() and onunload() should fire for xul overlays

Status: RESOLVED WONTFIX

(Core :: XUL, enhancement, P3)

Description

[hangas]

It would be useful to have the onload and onunload handler fire for overlay
files.  Sometimes it is useful to have an overlay that the main window has no
knoledge of, in these cases there is no way to trigger an onload to fire for this
added xul.

As a workaround, do this:

  function OnLoad() {
    // do whatever here
  }

  setTimeout("OnLoad();", 0);

good enough for me.  i won't be implementing this then.

reopening:
using the code below, menuElement returns null unless (at least on my machine),
the delay in setTimeout is set to at least 2000.  This is completely
unacceptable.  OnLoad() should fire on load, there should be no need for a timeout.

function InitElement(ElementID)
{
  var menuElement=document.getElementById("menu" + ElementID);
}

function OnLoad()
{
    InitElement("PTBookmarks");
}

Not if the element hasn't been merged in yet.  Besides, you can always manually 
add a load listener via script anyway using addEventListener.  There is no need 
for this functionality.
