数据库表中有一个单位表,里面包括ID、Name、Order等字段,现在有个后台管理功能,可以设置这些单位在某些统计表格中的先后显示顺序,于是想到用拖拽方式实现,这样操作起来更简便。
使用了GifCam软件做了一个示例动画,效果如下图所示:
于是就动手起来,发现jquery.ui中提供sortable函数,可用于排序,界面中从数据库绑定的单位使用Repeater控件,下面简单介绍下主要步骤:
1、项目中使用到的jquery-1.7.2.min.js和jquery-ui.min.js请点击进行下载,地址为:http://download.csdn.net/detail/taomanman/9315373
