Beginning Google Maps Mashups with Mapplets, KML, and GeoRSS: From Novice to Professional

APPENDIX CJavaScript Techniquesfor Map Developers

In this appendix you'll find a few slightly more advanced JavaScript techniques to improve your map pages and make the task of developing them easier. First up are two debugging tools, crucial weapons in the daily struggle against recalcitrant code. They're followed by a little-used API feature to improve your page structure; a code snippet to handle Google Maps API keys for multiple domains; and finally, a feature borrowed from the Gadgets API to make your mapplets more scalabel.

Like all the appendixes, this one is primarily meant as a reference to dip into as needed while working through the rest of the book. Different topics here will be useful to you at different times.
