jQuery—EasyUI小案列 – 偶my耶

jQuery EasyUI为提供了大多数UI控件的使用,如:accordion,combobox,menu,dialog,tabs,validatebox,datagrid,window,tree等等。
jQuery EasyUI是基于JQuery的一个前台ui界面的插件,功能相对没extjs强大,但页面也是相当好看的,同时页面支持各种themes以满足使用者对于页面不同风格的喜好。一些功能也足够开发者使用,相对于extjs更轻量。
jQuery EasyUI有以下特点:
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
