Question

您需要导出文件xlsx格式，但我确实有嵌套数据 json数组格式由于这个我无法获取数据，可以任何一个帮助我，因为我试图但不能正确获取数据

    <html ng-app="myApp">
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
    <script src="alasql.min.js"></script>
    <script src="xlsx.core.min.js"></script>

    <script src="https://rawgithub.com/eligrey/FileSaver.js/master/FileSaver.js" type="text/javascript"></script>
<button ng-click="exportData()">Export</button>
    <div ng-controller="myCtrl">
    <html>

我的脚本是

.fucntion($scope){
 $scope.inverters = [
  {
    "InvDetails": "UPS",
    "LstRecords": [
      {
        "Id": 1,
        "Invertor_Id": 1,
        "Time_of_Reading": "20170214",
        "Lastreading": 0,
        "Readingby": 0
      },
      {
        "Id": 87,
        "Invertor_Id": 1,
        "Time_of_Reading": "20170215",
        "Lastreading": 5,
        "Readingby": 10
      },
      {
        "Id": 110,
        "Invertor_Id": 1,
        "Time_of_Reading": "20170216",
        "Lastreading": 10,
        "Readingby": 92
      },
      {
        "Id": 111,
        "Invertor_Id": 1,
        "Time_of_Reading": "20170216",
        "Lastreading": 92,
        "Readingby": 95
      }
    ]
  },
  {
    "InvDetails": "Power Supply",

    "LstRecords": [
      {
        "Id": 2,
        "Invertor_Id": 2,
        "Time_of_Reading": "20170214",
        "Lastreading": 0,
        "Readingby": 0
      },
      {
        "Id": 88,
        "Invertor_Id": 2,
        "Time_of_Reading": "20170215",
        "Lastreading": 7,
        "Readingby": 13
      },
      {
        "Id": 109,
        "Invertor_Id": 2,
        "Time_of_Reading": "20170216",
        "Lastreading": 13,
        "Readingby": 25
      },
      {
        "Id": 112,
        "Invertor_Id": 2,
        "Time_of_Reading": "20170216",
        "Lastreading": 25,
        "Readingby": 49
      }
    ]
  }
];
$scope.exportData = function () {
        var data="";
        $scope.headers=[];
         angular.forEach($scope.inverters,function(value,key){

        var we=value.InvDetails;
        $scope.headers.push(we);
        $scope.last=value.LstRecords;
        angular.forEach($scope.last,function(value,key){

            data={
                "Id": value.Id,
                "Invertor_Id": value.Invertor_Id,
                "Time_of_Reading":value.Time_of_Reading,
                "Lastreading": value.Lastreading,
                 "Readingby": value.Readingby
            };
        })
    })

         $scope.result=[];
         $scope.result0=[];

         $scope.result.push({
            "Invertor1":JSON.stringify(data)


         })

        alasql('SELECT * INTO XLSX("john.xlsx",{headers:true}) FROM ?',[result]);
    };
};

任何人都可以帮我解决如何导出这个，如果我需要拆分数据，因为我从API获取数据，所以如果你拆分并导出它将有用的形式是任何其他解决方案是有意味着让我知道该怎么做。提前谢谢

您可以使用SEARCH运算符：

alasql('SEARCH / AS @r     \
        LstRecords / AS @l \
        RETURN(@r->InvDetails AS InvDetails,  \
               @l->Id AS Id,                  \
               @l->Invertor_Id AS Inventor_Id \
        ) \
        INTO XLSX("john.xlsx",{headers:true}) FROM ?',[result]);

这里AlaSQL遍历第一个数组并将当前记录保存到@r临时变化。然后它遍历嵌套的LstRecords数组并将其保存到@l变量。 RETURN子句生成包含所有必填字段的结果对象。

如何将嵌套的json数组数据解析（转换）为angularjs中的csv格式以导出文件xlsx格式
