javascript - 将项目推送到 JSON 数组中

Question

我有一个 JavaScript 函数，它可以对 API 进行 ajax 调用，并获取一个 JSON 数组。

这是我得到的数组示例:

[
  {
    "ErrorType": "Errors",
    "Explanations": [
      {
        "Explanation": "Price Missing",
        "Locations": [
          25,
          45
        ]
      },
      {
        "Explanation": "Unit of measurement not valid",
        "Locations": [
          25,
          301,
          302
        ]
      }
    ]
  },
  {
    "ErrorType": "Warnings",
    "Explanations": [
      {
        Blablabla,
        Ithinkthere's already much here
      }
    ]
  }
]

我将它放入 JavaScript 数组中:

$scope.CorrectionDatas = ResponseFromApi;

因此，对于每个 ErrorType，我都有一些“解释”。我想添加另一个属性，以便有这样的东西:

[
  {
    "ErrorType": "Errors",
    "Explanations": [
      {
        "Explanation": "Price Missing",
        "Locations": [
          25,
          45
        ]
      },
      {
        "Explanation": "Unit of measurement not valid",
        "Locations": [
          25,
          301,
          302
        ]
      }
    ],
    "show": true
  },
  {
    "ErrorType": "Warnings",
    "Explanations": [
      {
        Blablabla,
        Ithinkthere's already much here 
      }
     ],
    "show":true
  }
]

我认为我只能这样做:

$scope.CorrectionDatas.forEach(function (error) {
    error.push({ show: true });
});

但是我的调试器给了我一个错误:

Error: error.push is not a function 
$scope.getErrors/</<@http://localhost:1771/dependencies/local/js/Correction/CorrectionCtrl.js:26

Answer 1

每个错误都是一个对象，因此它没有推送，代码应该是:

        $scope.CorrectionDatas.forEach(function(error) {
            error.show = true;
        });
