Question

我想要构建一个excel uploader应用程序。现在，我可以从excel文件中获取数据并将其发送到API来存储信息。

但是我还需要其他东西，并且要将每个值作为excel的id，这是我先保存后得到的。

这是我在存储之前获取excel数据的方式：

$scope.loadWorksheet = function(e){

        var file = e.target.result;
        var workbook = XLSX.read(file, { type: "binary" });


        var sheetName = workbook.SheetNames[0];
        $scope.sheet = XLSX.utils.sheet_to_json(workbook.Sheets[sheetName]);

       console.log($scope.sheet);

        $scope.$apply();

      };

假设我得到下一个阵列：

[{Name: "Chuck", Age: "30"},
{Name: "Marcus", Age: "18"},
{Name: "Shelly", Age: "29"}]

如何向每条记录添加文档的ID？

每个例子，在保存文档后，我得到了响应id：

$scope.IdDocument = 15;

我需要的是将它放在每条记录上，如下：

[{Name: "Chuck", Age: "30", DocumentId: "15"},
{Name: "Marcus", Age: "18" DocumentId: "15"},
{Name: "Shelly", Age: "29" DocumentId: "15"}]

有办法吗？希望你能帮帮我。

我正在使用AngularJs和Javascript。

Answer 1

您需要 forEach ，您可以使用angularjs angular.forEach

<强>样本

＆＃13;

var array = [{Name: "Chuck", Age: "30"},
{Name: "Marcus", Age: "18"},
{Name: "Shelly", Age: "29"}];

array.forEach(function(obj) { obj.DocumentId = "15"; });

console.log(array);

Answer 2

您可以遍历数组并按如下所示添加字段

var people = [{Name: "Chuck", Age: "30"},
                  {Name: "Marcus", Age: "18"},
                  {Name: "Shelly", Age: "29"}
                 ];
    
    people.forEach(p => p.DocumentId = "15");
    console.log(people)

Answer 3

使用map函数。它将返回更新的数组

＆＃13;

var oldArray = [{
    Name: "Chuck",
    Age: "30"
  },
  {
    Name: "Marcus",
    Age: "18"
  },
  {
    Name: "Shelly",
    Age: "29"
  }
];

var newArray = oldArray.map(function(item) {
  item.DocumentId = '15';
  return item;

})

console.log(newArray)

＆＃13;

Answer 4

使用for循环遍历数组对象

var people = [{Name: "Chuck", Age: "30"},
             {Name: "Marcus", Age: "18"},
             {Name: "Shelly", Age: "29"}];


 for(var i=0 ; i<people.length;i++){
      people[i].age = "10";
 }

将新值添加到json
