Implement reusable Ajax components through JSF 2 (1)

BKJIA introduced the Ajax support package to readers and used "Ajax to listen to events and errors in the JSF 2 client processing code ". Today, the BKJIA editor recommends that you use the combination of composite components and Ajax to easily support Ajax custom components.

This series of JSFfu series is based on the concept of an introduction to the same name by David Geary. This series will explore JSF2 and its ecosystem in depth and introduce how to integrate Java EE technologies such as Contexts and DependencyInjection with JSF.

In this article, I will show you how to implement the Automatic completion component, which uses Ajax to manage its Completion list. In this process, you will learn how to integrate Ajax into your own composite components.

This series of code is based on JSF2 running in enterprise containers, such as GlassFish or Resin. The last part of this article will detail how to install and run the code in this article using GlassFish.

JSF automatically completes custom components

The AutoComplete field, also known as the recommendation box, is a combination of many Web applications. They are also typical Ajax applications. The Automatic completion field includes many Ajax frameworks, such as Scriptaculous and JQuery. For details about Automatic completion component integration for 1-AjaxDaddy, see references.)-see:

This article will discuss how to use JSF to implement automatic completion fields that support Ajax. You will learn how to implement the Automatic completion field shown in 2. A brief virtual country list is displayed, which is selected from the "virtual country list" in Wikipedia. See References ):
