AngularJs导出数据到Excel的示例代码

<div id="exportable">
 <table width="100%">
 <thead>
 <tr>
 <th>Name</th>
 <th>Email</th>
 </tr>
 </thead>
 <tbody>
 <tr>
 <td>小明</td>
 <td>dsds@163.com</td>
 </tr>
 </tbody>
 </table>
</div>

var blob = new Blob([document.getElementById('exportable').innerHTML], {
 type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;charset=utf-8"
 });
 saveAs(blob, "日记账.xls");
};

\\ angular 需要导入xlsx.core.min.js alasql.min.js
\\ 文件结构 
 var arr = [
 {
 '收入':1,
 '支出':2,
 '结存':3
 },
 {
 '收入':4,
 '支出':5,
 '结存':6
 }
 ]

\\ 生成 excel 文件
alasql('SELECT * INTO XLSX("日记账.xlsx",{headers:true}) FROM ?',[arr]);

// 导出excel

 $scope.exportToExcel=function(){
 var data = angular.copy($scope.pageData.list)
 var arr = [];
 var type = null;

 var amountOUT = 0;
 angular.forEach(data,function (item) {
 // 兑付情况
 if(item.isHappened){

 }else{

 }
 // 收入
 if(item.itemModel=='INCOME'){
