在数组中添加值，该数组是对象数组的一部分

Question

我想在作为对象fwnodes数组一部分的数组末尾添加新值。 firstNodeKey是fwnodes内部的数组。

我在fwnodes下面给出了一些对象。现在，我想填充firstNodeKey数组一个将根据条件选择的对象。

var fwnodes = [{
      key: "10.0.0.1",
      label: "10.0.0.1",
      shape: $scope.vis.params.shapeFirstNode,
      color: $scope.vis.params.firstNodeColor,
      firstNodeKey: [],
      secondNodeKey: []
    },
    {
      key: "10.1.0.1",
      label: "10.1.0.1",
      shape: $scope.vis.params.shapeFirstNode,
      color: $scope.vis.params.firstNodeColor,
      firstNodeKey: [],
      secondNodeKey: []
    },
    {
      key: "10.2.0.0",
      label: "10.2.0.0",
      shape: $scope.vis.params.shapeFirstNode,
      color: $scope.vis.params.firstNodeColor,
      firstNodeKey: [],
      secondNodeKey: []

    },
    {
      key: "10.201.0.2",
      label: "10.201.0.2",
      shape: $scope.vis.params.shapeFirstNode,
      color: $scope.vis.params.firstNodeColor,
      firstNodeKey: [],
      secondNodeKey: []

    },
    {
      key: "10.50.0.1",
      label: "10.50.0.1",

      shape: $scope.vis.params.shapeFirstNode,
      color: $scope.vis.params.firstNodeColor,
      firstNodeKey: [],
      secondNodeKey: []
    },
    {
      key: "10.30.0.2",
      label: "10.30.0.2",
      shape: $scope.vis.params.shapeFirstNode,
      color: $scope.vis.params.firstNodeColor,
      firstNodeKey: [],
      secondNodeKey: []
    },
    {
      key: "10.20.0.1",
      label: "10.20.0.1",
      shape: $scope.vis.params.shapeFirstNode,
      color: $scope.vis.params.firstNodeColor,
      firstNodeKey: [],
      secondNodeKey: []
    }]

预期结果：

var fwnodes = [{
      key: "10.0.0.1",
      label: "10.0.0.1",
      shape: $scope.vis.params.shapeFirstNode,
      color: $scope.vis.params.firstNodeColor,
      firstNodeKey: ["10.0.0.34", "10.0.0.24", "10.0.0.76"],
      secondNodeKey: []
    },
    {
      key: "10.1.0.1",
      label: "10.1.0.1",
      shape: $scope.vis.params.shapeFirstNode,
      color: $scope.vis.params.firstNodeColor,
      firstNodeKey: ["10.1.0.30", "10.1.0.45"],
      secondNodeKey: []
    },
    {
      key: "10.2.0.0",
      label: "10.2.0.0",
      shape: $scope.vis.params.shapeFirstNode,
      color: $scope.vis.params.firstNodeColor,
      firstNodeKey: [],
      secondNodeKey: []

    },
    {
      key: "10.201.0.2",
      label: "10.201.0.2",
      shape: $scope.vis.params.shapeFirstNode,
      color: $scope.vis.params.firstNodeColor,
      firstNodeKey: [],
      secondNodeKey: []

    },
    {
      key: "10.50.0.1",
      label: "10.50.0.1",

      shape: $scope.vis.params.shapeFirstNode,
      color: $scope.vis.params.firstNodeColor,
      firstNodeKey: [],
      secondNodeKey: []
    },
    {
      key: "10.30.0.2",
      label: "10.30.0.2",

      shape: $scope.vis.params.shapeFirstNode,
      color: $scope.vis.params.firstNodeColor,
      firstNodeKey: [],
      secondNodeKey: []
    },
    {
      key: "10.20.0.1",
      label: "10.20.0.1",
      shape: $scope.vis.params.shapeFirstNode,
      color: $scope.vis.params.firstNodeColor,
      firstNodeKey: [],
      secondNodeKey: []
    }]
