ExtJs框架下Grid组件的扩展及应用

Discussion of grid components for ExtJs

依据经济金融管理系统数据库具有一对多、多对多关系的特点,设计实现了一个基于J2EE技术并结合ExtJs框架的系统。针对数据指标种类繁多的特性,着重对ExtJs中Grid组件的扩展改进进行讨论,并在此基础上实现了系统的动态列表格数据显示。提高了系统的扩展性和开发效率,并为类似数据库系统开发提供借鉴。

Based on the database of economic and financial management system with one-to-many and many-to-many characteristics of the relationship, designed the system which based on J2EE technology combined with ExtJs framework. Indicators and data for a wide variety of features, focused on the extension of ExtJs grid component to discuss improvements, on the basis of which the system achieved a dynamic list of grid data. The extension of ExtJs grid component effective solves system scalability and high etiieient development and provides reference for similar characteristics of the database system development.
