# 使用jQuery EasyUI的 detailview创建分组表格 #

## > 第一次使用markdown编辑，不太会编辑，布局有点乱。 ##

## 先见效果图 ##

![这里写图片描述][SouthEast]

![这里写图片描述][SouthEast 1]

## 下面说下使用方法 ##

--------------------

### 依赖的js以及css文件 ###

![这里写图片描述][SouthEast 2]

### **引入了bootstrap，跟折叠表格功能无关的，只是因为项目中其他位置需要，该折叠表格是easyui的一个组件，跟bootstrap无关的** ###

--------------------

### html文件内容 ###

> html中仅需一个table标签即可。

## js如何使用 ##

> 注意url地址的table1.json和table2.json，渲染表格必须使用规定格式的json，下面我会给出detailview能接受的json的格式。本文例子使用js读取的本地的json文件，如果你使用ajax来加载的话，请在url地址那里改为请求地址即可，一定要保证返回的json格式与规定格式相同。

**table.js文件内容**

$(function () { $('#dg').datagrid({ view: detailview, width:'auto', url:'table1.json',//使用ajax加载的话修改这个url地址 height:'auto', fitColumns:true,//会自动扩大或缩小列的尺寸以适应网格的宽度并且防止水平滚动 rownumbers: true,//行号 columns: [[ {field: 'id1', checkbox: 'true'}, {field: 'id', title: '入库单号', styler: cellStyler}, {field: 'zhuangtai', title: '当前状态', styler: cellStyler}, {field: 'name', title: '供货单位', styler: cellStyler}, {field: 'time', title: '入库时间', styler: cellStyler}, {field: 'type', title: '入库方式', styler: cellStyler}, {field: 'zdlb', title: '账单类别', styler: cellStyler}, {field: 'num', title: '发票数量（张）', styler: cellStyler}, {field: 'leibie', title: '药品种类（种）', styler: cellStyler}, {field: 'shizhi', title: '实支金额合计', styler: cellStyler}, {field: 'pifa', title: '批发金额合计', styler: cellStyler}, {field: 'lingshou', title: '零售金额合计', styler: cellStyler} ]], onBeforeLoad: function (index, row) { /* console.log('loading');*/ }, detailFormatter: function (index, row) { // console.log('detailFormatter--index:'+index+'--'+'row:'+row); return '<div style="padding:2px"><table id="ddv-' + index + '"></table></div>'; }, onExpandRow: function (index, row) { //当展开一行时触发。 //console.log('onExpandRow---index:'+index+'--'+'row:'+row) $('#ddv-' + index).datagrid({ fitColumns:true,//会自动扩大或缩小列的尺寸以适应网格的宽度并且防止水平滚动 rownumbers: true, url:'table2.json',//使用ajax加载的话修改这个url地址 loadMsg: '加载中...', height: 'auto', columns: [[ {field: 'id', checkbox: 'true'}, {field: 'code', title: '发票号'}, {field: 'name', title: '名称'}, {field: 'size', title: '规格'}, {field: 'num1', title: '实物数量'}, {field: 'num2', title: '发票数量'}, {field: 'koulv', title: '扣率'}, {field: 'leixing', title: '类型'}, {field: 'zhuangtai', title: '状态'}, {field: 'shizhi', title: '实支金额'}, {field: 'pifa', title: '批发金额'}, {field: 'lingshou', title: '零售金额'}, ]], onResize: function () { $('#dg').datagrid('fixDetailRowHeight', index); $('#dg').datagrid('fixRowHeight', index); }, onLoadSuccess: function () { setTimeout(function () { $('#dg').datagrid('fixDetailRowHeight', index); $('#dg').datagrid('fixRowHeight', index); }, 0); } }); $('#dg').datagrid('fixDetailRowHeight', index); $('#dg').datagrid('fixRowHeight', index); } }); }); /*修改单元格背景色*/ function cellStyler(value, row, index) { return 'color:blue;'; }
