• 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。
