the course of displaying the frame’s page (except in NN4/Mac, which exhibits a bug
for this property in a dynamically written document). The fact that you can artificially
create full-fledged JavaScript document objects on the fly represents one of the most
important powers of serverless CGI scripting (for information delivery to the user)
with JavaScript. You have much to take advantage of here if your imagination is up to
the task.
Notice that except for NN2, you can easily modify Listing 18-17 to write the
results to the same frame as the document containing the field and buttons. Instead
of specifying the lower frame
parent.frames[1].document.open()
parent.frames[1].document.write(msg)
parent.frames[1].document.close()
the code simply can use
document.open()
document.write(msg)
document.close()
This code would replace the form document with the results and not require any
frames in the first place. Because the code assembles all of the content for the new
document into one variable value, that data survives the one document.write()
method.
The frameset document (Listing 18-18) creates a blank frame by loading a blank
document (Listing 18-18). An alternative I highly recommend is to have the framesetting
document fill the frame with a blank document of its own creation. See
“Blank Frames” in Chapter 16 of the JavaScript Bible for further details about this
technique for NN3+ and IE3+.

Example
Listing 18-19 provides a simple example of an intentional infinitely looping script.
In case you load this page into a browser other than IE5, you can click the Halt
Counter button to stop the looping. The Halt Counter button and the onStop event
handler invoke the same function.
