Looking for an alternative to window.showModalDialog

The app I am working on used windows.showModalDialog which depreciated, so I replaced it with window,.open which workd fine but with one issue - it is not modal. I have found that one can use window.open Dialog instead but replacing window.open with window.openDialog broke my links.

I had

    ret = window.open(target, "", "scrollbars=no,location=no,statusbar=no,menubar=no,resizable=no,width=500,height=300");

Select allOpen in new window

which worked, so I tried:

    ret = window.openDialog(target, "", "scrollbars=no,location=no,statusbar=no,menubar=no,resizable=no,width=500,height=300");

Select allOpen in new window

which did not.


I was also looking into using JQuery UI dialog or AJAX dialog, but it seems that those would just display  limited content that you specify and I need to display an actual page. Can anyone help?
