In Listing 16-4, I have created the ultimate cross-platform window opening and
closing sample. It takes into account the lack of the opener property in Navigator 2,
the missing closed property in Navigator 2 and Internet Explorer 3, and it even provides
an ugly but necessary workaround for the inability of Internet Explorer 3 to
gracefully see if a subwindow is still open.
The script begins by initializing a global variable, newWind, which is used to hold
the object reference to the second window. This value needs to be global so that
other functions can reference the window for tasks, such as closing. Another global
variable, isIE3, is a Boolean flag that lets the window closing routines know
whether the visitor is using Internet Explorer 3 (see details about the navigator.
appVersion property in Chapter 28 of the JavaScript Bible).
For this example, the new window contains some HTML code written dynamically
to it, rather than loading an existing HTML file into it. Therefore, the URL parameter
of the window.open() method is left as an empty string. It is vital, however, to
assign a name in the second parameter to accommodate the Internet Explorer 3
workaround for closing the window. After the new window is opened, an opener
property is assigned to the object if one is not already assigned (this property is
needed only for Navigator 2). Next comes a brief delay to allow Internet Explorer
(especially versions 3 and 4) to catch up with opening the window so that content
