如何解析（转换）嵌套的JSON数组数据放入angularjs CSV格式导出的文件XLSX格式

-1

嗨需要导出文件的xlsx格式，但我确实有嵌套 JSON阵列格式的数据，由于该即时通讯无法获取数据，可以在任何一个帮我在这，因为我尝试，但没有得到正确的数据如何解析（转换）嵌套的JSON数组数据放入angularjs CSV格式导出的文件XLSX格式

<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>

我的剧本是

.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]); 
    }; 
};

可以帮助我如何导出这一个，如果我需要拆分数据，因为即时通讯从API获取数据，所以如果你分裂和出口这个它将是有益的形式是任何其他解决方案是否意味着让我知道该怎么做。在此先感谢

您可以使用搜索操作符：

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走到第一阵列，并保存当前记录到@r临时varyable。然后它遍历嵌套的LstRecords数组并将其保存到@l变量。 RETURN子句用所有必要的字段生成结果对象。

但我的数据基础已经在mysql中创建了，我如何在这里使用alasql。你可以让我知道一点，因为即时混淆在那 – Rocker
