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>
