Last week Tim and I showed off some of the Ajax functionality that we are working on for the upcoming ColdFusion Scorpio. One of the controls we demonstrated was an auto-suggest control implemented as an extension to the existing <cfinput>l tag. As demonstrated, the tag can be used in two ways. It can use a hard coded list, like this:
Of course, the list need not be static, it could be programmatically generated at runtime as needed. This is an ideal option for shorter lists.
For longer lists the suggestions can be populated via asynchronous calls back to a ColdFusion Component on the server after a delay in typing. The syntax would look something like this:
This points to a CFC named fruit.cfc in the same folder and invoked a method named getFruit() passing the current field value as an argument. The invoked method receives that argument as a string, does whatever processing it needs (perhaps using it in a
Of course, all of this is subject to change, but you get the idea.
