概述
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:

后台:
public ActionResult Search(DataTable dt) { int total; IQueryable<Model.Power> powerIq = CurrentBllSession.PowerBll.GetIQueryable(); total = powerIq.Count(); List<Model.Power> powerList = powerIq.ToList(); powerList = TreeGridList(powerList); dt.recordsTotal = total; dt.recordsFiltered = total; dt.data = powerList; return Json(dt); } /// <summary> /// 将List转换为TreeGrid格式的List /// </summary> private List<Model.Power> TreeGridList(List<Model.Power> powerList) { List<Model.Power> treegridList=new List<Model.Power>(); foreach (var powerOne in powerList.Where(a => a.ParentId == "0" || a.PowerId.Length == 4).OrderBy(a => a.Sort))//一级菜单 { treegridList.Add(powerOne); foreach (var powerTwo in powerList.Where(a => a.ParentId != "0" && a.PowerId.Length == 8 && a.ParentId == powerOne.PowerId).OrderBy(a=>a.Sort))//二级菜单 { treegridList.Add(powerTwo); foreach (var powerBtn in powerList.Where(a => a.ParentId != "0" && a.PowerId.Length == 8 && a.ParentId == powerTwo.PowerId).OrderBy(a => a.Sort))//按钮 { treegridList.Add(powerBtn); } } } return treegridList; }
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。
