Easyui 之 Treegrid 笔记
EasyUI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
varpls=ListAll(p.PartChild).ToList(); List<Object>result=newList<object>(); foreach(variteminpls) { 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 //Objectl=new{id=item.ListID,text=item.PartChild,_parentId=0,Qty=item.Qty,Rem=item.Rem,chlidren=TreeList(pls,item.PartChild)}; //result.Add(l); } else { varparent=fromainpls wherea.PartChild==item.PartParent selecta; result.Add(new{id=item.ListID,goodsid=item.PartChild,_parentId=parent.First().ListID,Qty=item.Qty,Rem=item.Rem}); } }
这是前台View
<divstyle="margin:20px0;"></div> <tabletitle="PartsList"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> <thdata-options="field:'goodsid'"width="100">goodsid</th> <thdata-options="field:'id'"width="100">ListID</th> <thdata-options="field:'ListVer'"width="100"align="right">ListVer</th> <thdata-options="field:'ParentName'"width="100">ParentName</th> <thdata-options="field:'Qty'"width="50">Qty</th> <thdata-options="field:'Rem'"width="50">Rem</th> <thdata-options="field:'_parentId'"width="50">parent</th> </tr> </thead> </table>
