jquery插件treegrid树状表格的使⽤⽅法详解（.Net平台）⼀、使⽤treegrid，需要以下⽀持
jquery.min.id.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：
@using Model
@{
Layout = null;
UserInfo userInfo = null;
if (ViewData["LoginUser"] != null)
{
userInfo = ViewData["LoginUser"] as UserInfo;
}
else
{
Response.Redirect("/Login/Index");
}
}

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。
