AJAX Example

Select a country from the form. This will query the database. If it has a region associated with it (i.e. Australia), a "Region" option will appear.

Select a country:

Note: If you don't see a 2nd drop down menu appear when you select a country, your browser might not support AJAX. Note that not all countries have regions associated with them so try selecting "Australia" to see if the 2nd drop down appears.

How Does This Work?

The contents of this 2nd drop down menu is being populated from a database. When you select the country, this triggers off the AJAX. JavaScript, ColdFusion, XML, and SQL all contributed to populating this option.

The following lesson shows you the code used to create this AJAX example.
