How Ajax is implemented in the Zend framework

In this paper, we introduce the method of implementing Ajax in Zend Framework framework, and analyze the specific steps and related operation skills of Ajax function in Zend Framework frame in detail, and hope to help everyone.

Development platform: Windows XP SP2
Test Platform: FreeBSD 7.0
Development tools: Netbeans 6.1
Working with Frames: Zend Framework 1.5.2
Database: MySQL 5.0.51a

Required database tables and ZF-related directories and files:

One, table:

Mysql> SELECT * from news;+----+-------+---------------------+| ID | Title | add_time| +----+-------+---------------------+| 22 | Rot |  2008-01-04 00:00:00 | | | | AAA  | 2008-01-04 00:00:00 | | | Rot  | 2008-01-04 00:00:00 | | | | dfeew | 2008-02-27 00:00:00 | | 26 | Jesse | 2008-02-27 00:00:00 | | 27 | Andle | 2008-02-27 00:00:00 | | 28 | Andle | 2008-02-27 00:00:00 |+----+-------+---------------------+
