Figure 4-2 shows an example of the frame written by the script.
Figure 4-2: Clicking the Write To Below button in the upper frame causes a script to

A second point to note is that this example customizes the content of the document
based on user input. This customization makes the experience of working

The third point I want to bring home is that the document created in the separate
frame by the document.write() method is a genuine document object. In this example,
for instance, the tag of the written document changes if you redraw the
lower frame after changing the entry of the name field in the upper frame. If you click
the lower button after updating the bottom frame, you see that the document.title
property has, indeed, changed to reflect the tag written to the browser in
