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

      if(item.isHappened){
        type = '未兑付'
      }else{
        type = '已兑付'
      }
      // 收入

      })
    })
    if(arr.length < 1){
      ToasterTool.error('暂无数据，导出失败！');
    }else{
      // alasql('SELECT * INTO XLSX("日记账.xlsx",{headers:true}) FROM ?',[arr]);
      
      alasql.promise('SELECT * INTO XLSX("日记账-'+ DateTool.format(new Date(),'yyyy-MM-dd HH:mm:ss') + "-"+ $scope.loginUser.userName +'.xlsx",{headers:true}) FROM ?',[arr])
        .then(function (data) {
