java：easyui（jQueryEasyUI，分页）

1.介绍：

　　jQuery EasyUI是一组基于jQuery的UI插件集合体，而jQuery EasyUI的目标就是帮助web开发者更轻松的打造出功能丰富并且美观的UI界面。开发者不需要编写复杂的javascript，也不需要对css样式有深入的了解，开发者需要了解的只有一些简单的html标签。

2.特点：

　　 1、基于jquery用户界面插件的集合
　　2、为一些当前用于交互的js应用提供必要的功能
　　3、EasyUI支持两种渲染方式分别为javascript方式（如：$('#p').panel({...})）和html标记方式（如：class="easyui-panel"）
　　4、支持HTML5（通过data-options属性）
　　5、开发产品时可节省时间和资源
　　6、简单，但很强大
　　7、支持扩展，可根据自己的需求扩展控件
　　8、目前各项不足正以版本递增的方式不断完善
