EasyUI 簡(jiǎn)介

easyui是一種基于jQuery的用戶界面插件集合。

easyui為創(chuàng)建現(xiàn)代化，互動(dòng)，JavaScript應(yīng)用程序，提供必要的功能。

使用easyui你不需要寫很多代碼，你只需要通過編寫一些簡(jiǎn)單HTML標(biāo)記，就可以定義用戶界面。

easyui是個(gè)完美支持HTML5網(wǎng)頁的完整框架。

easyui節(jié)省您網(wǎng)頁開發(fā)的時(shí)間和規(guī)模。

easyui很簡(jiǎn)單但功能強(qiáng)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(jié)點(diǎn)；

2.根節(jié)點(diǎn)一個(gè)或多個(gè)均可；

4.根節(jié)點(diǎn)的父節(jié)點(diǎn)屬性不必定義，或者定義為0；

5.各級(jí)子節(jié)點(diǎn)的父節(jié)點(diǎn)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.不必在后臺(tái)ACTION中輸出“樹”形結(jié)構(gòu)的json數(shù)據(jù)，只要下面結(jié)構(gòu)的json給前臺(tái)的treegrid，就可以建立樹形輸出到頁面。（了解到后臺(tái)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 });

//下面是調(diào)用生成樹形數(shù)據(jù)方法的語句,多余！easyui可根據(jù)parentID自動(dòng)建樹

//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 });

}

}

這是前臺(tái)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>
