jquery-treegrid树状表格的使用（.Net平台）

上一篇介绍了DataTable，这一篇在DT的基础之上再使用jquery的一款插件：treegrid,官网地址：http://maxazan.github.io/jquery-treegrid/

一、使用treegrid，需要以下支持

jquery.min.js+jquery.treegrid.min.js

二、后端提供树状列表格式的集合数据，借助前端的DT的配置控制，来在页面上输出满足treegrid格式要求的html

前台：

  1 @using Model
  2 @{
  3     Layout = null;
  4     UserInfo userInfo = null;
  5 
  6     if (ViewData["LoginUser"] != null)
  7     {
  8         userInfo = ViewData["LoginUser"] as UserInfo;
  9     }
 10     else
 11     {
 12         Response.Redirect("/Login/Index");
 13     }

解释说明：

treegrid是通过tr标签上的class内容和tr的位置关系来组织表格中行之间的父子关系和位置关系的，

DT中的配置项：

"rowCallback": function (row, data, displayIndex) {//行定义
                if (data.ParentId != "0") {
                    $(row).attr("class", "text-c treegrid-" + data.PowerId + " treegrid-parent-" + data.ParentId);
                } else {
                    $(row).attr("class", "text-c treegrid-" + data.PowerId);
                }
            },

就是来控制父子关系的。

而后台的List顺序转换，是为了调整好输出的顺序，从而来控制tr之间的位置关系。

通过DT初始化好表格之后，调用

$("#table1").treegrid({
"initialState": 'collapsed',
});

即可，绘制好树状表格。
