Behaviour of window.focus() with IE8


I am trying to simulate the functionality of modal dialog windows using javascript..

I would do this by invoking the window.focus method of the dialog window whenever the parent window gets focus.

This has worked fine with IE6 and with IE7 ; but with IE 8 - it works well on some workstations; however on other workstations all that happens is that the taskbar button for the dialog window flashes when window.focus() is invoked.. (the dialog window is not brought up to the front)


I open the dialog window like this:

dialogWin =window.open('aform.aspx','aaa', attr);

...

I handle the onfocus event of the opener window like this:

if (dialogWin != null && !dialogWin.closed)
{
            dialogWin.focus();
}


This has worked well with past versions of IE; however it does not work with IE 8 on some workstations (the button on the taskbar merely flashes)

Is there any other approach I can take?   I realize I can use showModalDialog; but this would involve rewriting a lot of code.



Thanks

Why would it involve a rewrite?

If you really want to, you can do

if (window.showModalDialog) window.open=new function(url,target,parms) {
  var ret = showModalDialog(url,window,parms.replace(',',';').replace('width','dialogWidth').replace('height','dialogHeight'); // add whatever you need
  return ret
}


so only where you need to manipulate the window afterwards do you need to change stuff and you can do a change of
opener.
to
if (window.dialogArguments) opener=window.dialogArguments

However a better choice is to use something like lightbox 2 or thickbox or greybox since it does not involve opening new windows which is blocked on many PCs
