Easyui 之 Treegrid 筆記_jquery

EasyUI 簡介

easyui是一種基於jQuery的使用者介面插件集合。

easyui為創建現代化，互動，JavaScript應用程序，提供必要的功能。

使用easyui你不需要寫很多程式碼，你只需要透過寫一些簡單HTML標記，就可以定義使用者介面。

easyui是個完美支援HTML5網頁的完整框架。

easyui節省您網頁開發的時間和規模。

easyui很簡單但功能強大的。

菜鳥初次使用，參考論壇中介紹的方法仍走了一些彎路，把自己遇到的問題記錄下來。

1.必須定義根節點；

2.根節點一個或多個均可；

4.根節點的父節點屬性不必定義，或定義為0；

5.各級子節點的父節點屬性名稱必須為「_parentId",不能用其它名稱，此名稱已在jquery.easyui.js中定義；

6.不必在後台ACTION中輸出「樹」形結構的json資料，只要下面結構的json給前台的treegrid，就可以建立樹狀輸出到頁。 （了解到後台以樹形children格式輸出也是一種選擇。）

{"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"}

這是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 });
}
} 

這是前台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>
