Chapter 5. Getting Useful Data

Google Suggest was one of the first Ajax applications: it's actually older than the name Ajax. Google Suggest alters the experience of filling in an HTML form. Normally, you fill in your data, click Submit, and cross your fingers; more than likely, you'll find out that you've requested a username that already exists, made a typo in your area code, or made some other simple error that you have to correct. Google Suggest changes all that: as you type in a field, it continuously shows you possible completions that match entries in the database.
