Examples Highlights
✦ Many site visitors (this author included) frown on the application of the
scrolling MARQUEE element because it tends to distract visitors, rather than
convey meaningful information. But if you insist on using it, Listing 19-3
demonstrates how scripts can control numerous behaviors.
✦ Listing 19-4 lets you examine how the NN6 (W3C DOM) Range object treats
boundary points within the node hierarchy of a document.
✦ To insert a node into an arbitrary point within another, see Listing 19-5’s application
of the Range.insertNode() method.
✦ Walk through the steps for Range.selectNode() method to see how to set a
range to encompass an entire node or its contents.
✦ Run Listing 19-8 to see how NN6 (W3C DOM) provides additional facilities
for manipulating text content within a node. The listing also demonstrates
try-catch error handling.
✦ Listing 19-10 shows the IE4+/Windows TextRange object’s way of comparing
range boundaries (the IE version of Listing 19-4).
✦ The TextRange object provides practical text search facilities, which are
demonstrated in Listing 19-11. In the process, several TextRange properties
and methods get a workout, including the use of bookmarks within a range. A
simple undo buffer adds to the user friendliness of the application.

Example
Listing 19-1 contains a page that demonstrates changes to the three FONT element
object properties: color, face, and size. Along the way, you can see an economical
use of the setAttribute() method to do the work for all of the property
changes. This page loads successfully in all browsers, but the SELECT lists make
changes to the text only in IE4+ and NN6+.
A P element contains a nested FONT element that encompasses three words
whose appearance is controlled by three select lists. Each list controls one of the
