Easyui 之 Treegrid 笔记
许好多 人气:0EasyUI 简介
easyui是一种基于jQuery的用户界面插件集合。
easyui为创建现代化，互动，JavaScript应用程序，提供必要的功能。
使用easyui你不需要写很多代码，你只需要通过编写一些简单HTML标记，就可以定义用户界面。
easyui是个完美支持HTML5网页的完整框架。
easyui节省您网页开发的时间和规模。
easyui很简单但功能强大的。
菜鸟初次使用，参考论坛中介绍的方法仍走了一些弯路，把自己遇到的问题记录下来。
1.必须定义根节点；
2.根节点一个或多个均可；
4.根节点的父节点属性不必定义，或者定义为0；
5.各级子节点的父节点属性名称必须为“_parentId",不能用其它名称，此名称已在jquery.easyui.js中定义；
6.不必在后台ACTION中输出“树”形结构的json数据，只要下面结构的json给前台的treegrid，就可以建立树形输出到页面。（了解到后台以树形children格式输出也是一种选择。）
{"total":17,"rows":[
{"id":3,"goodsid":36120,"Qty":2.0000,"Rem":"15"},{"id":4,"goodsid":36123,"Qty":1.0000,"Rem":"21"},{"id":5,"goodsid":36124,"Qty":2.0000,"Rem":"23"},{"id":8,"goodsid":36130,"Qty":1.0000,"Rem":"1"},{"id":9,"goodsid":36131,"Qty":1.0000,"Rem":"2"},{"id":10,"goodsid":36132,"Qty":1.0000,"Rem":"3"},{"id":11,"goodsid":36133,"Qty":1.0000,"Rem":"4"},{"id":12,"goodsid":36134,"_parentId":8,"Qty":1.0000,"Rem":"1"},{"id":13,"goodsid":36135,"_parentId":8,"Qty":2.0000,"Rem":"2"},{"id":14,"goodsid":36136,"_parentId":8,"Qty":1.0000,"Rem":"3"},{"id":15,"goodsid":36137,"_parentId":8,"Qty":1.0000,"Rem":"4"},{"id":16,"goodsid":36138,"_parentId":8,"Qty":3.0000,"Rem":"5"},{"id":17,"goodsid":36139,"_parentId":8,"Qty":1.0000,"Rem":"6"},{"id":18,"goodsid":36142,"_parentId":9,"Qty":1.0000,"Rem":"1"},{"id":19,"goodsid":36143,"_parentId":9,"Qty":1.0000,"Rem":"2"},{"id":20,"goodsid":36144,"_parentId":9,"Qty":1.0000,"Rem":"3"},{"id":21,"goodsid":36145,"_parentId":9,"Qty":1.0000,"Rem":"4"}

这是Action
var pls = ListAll(p.PartChild).ToList();
List<Object> result = new List<object>();
foreach(var item in pls)
{
if(item.PartParent == p.PartChild)
{
result.Add( new { id = item.ListID, goodsid = item.PartChild, Qty = item.Qty, Rem = item.Rem });
//下面是调用生成树形数据方法的语句,多余！easyui可根据parentID自动建树
//Object l = new { id = item.ListID, text = item.PartChild, _parentId = 0,Qty = item.Qty, Rem = item.Rem, chlidren = TreeList(pls, item.PartChild) };
//result.Add(l);
}
else
{
var parent = from a in pls
where a.PartChild == item.PartParent
select a;
result.Add(new { id = item.ListID, goodsid = item.PartChild, _parentId = parent.First().ListID, Qty = item.Qty, Rem = item.Rem });
}
}
这是前台View
<div style="margin:20px 0;"></div> <table title="Parts List" class="easyui-treegrid" style="height:250px" data-options=" url:'/ContosoBISite/PartsList/JList/', method: 'get', nowrap: false, rownumbers: true, animate: true, collapsible: true, fitColumns: true, idField: 'id', treeField: 'goodsid' "> <thead> <tr> <th data-options="field:'goodsid'" width="100">goodsid</th> <th data-options="field:'id'" width="100">ListID</th> <th data-options="field:'ListVer'" width="100" align="right">ListVer</th> <th data-options="field:'ParentName'" width="100">ParentName</th> <th data-options="field:'Qty'" width="50">Qty</th> <th data-options="field:'Rem'" width="50">Rem</th> <th data-options="field:'_parentId'" width="50">parent</th> </tr> </thead> </table>
