Angular js 在数组对象中使用 ng-repeat 设置默认选项卡

Question

我想在默认选项卡中显示每个选项卡的最后一个对象。现在我的界面是这样的：tab[0] last object is {"id": 8, "status": 1}, tab[1] last object is {"id": 8, "status": 1} 但这是错误的。我希望它看起来像这样：tab[0] last object is {"id": 5, "status": 0}, tab[1]last object is{"id": 8, "status": 1}`.

我的 json 数据是这样的：

[
  {
    "tab":[
            [
              {"id": 1, "status": 1},
              {"id": 2, "status": 1},
              {"id": 3, "status": 1},
            ],
            [
              {"id": 4, "status": 1},
            ],
            [
              {"id": 5, "status": 0}
            ]
          ]
  },
  {
    "tab":[
            [
              {"id": 6, "status": 1},
              { "id": 7, "status": 1},  
            ],
            [
              {"id": 8, "status": 1}
            ]
          ]
  },
];

我的js：

for(let i = 0; i < $scope.data.length; i++) {
    for(let j = 0; j < $scope.data[i].tab.length; j++) { 
        $scope.selecttab = $scope.data[i].tab[j];
    }
}

$scope.getTab = function(obj) {
    $scope.selecttab = obj;
};

我的html

<div ng-repeat="obj in data">
    <ul class="nav nav-tabs">
        <li ng-class="{ active: selecttab == obj1 }" ng-repeat="obj1 in obj.tab track by $index">
            <a href ng-click="getTab(obj1)">{{ $index }}</a>
        </li>
     </ul>
     <div class="tab-content" ng-repeat="obj1 in selecttab">
         ID: {{obj1.id}}<br>
         Status : {{obj1.status}}
     </div>
</div>

有人可以帮助确定我做错了什么吗？

您必须更正上次的选项卡选择逻辑。

由于 selectedTab 特定于您的数据数组中的每个节点，因此我解析了数组并向每个包含第一个数据节点的数据节点添加了 selectedTab 属性。

工作fiddle

var app = angular.module('myApp', []);
app.controller('myCtrl', function ($scope) {
  $scope.data = [
    {
      "tab": [
        [{ "id": 1, "status": 1 }, { "id": 2, "status": 1 }, { "id": 3, "status": 1 }],
        [{ "id": 4, "status": 1 }],
        [{ "id": 5, "status": 0 }]
      ]
    },
    {
      "tab": [
        [{ "id": 6, "status": 1 }, { "id": 7, "status": 1 }],
        [{ "id": 8, "status": 1 }]
      ]
    },
  ];
  for (let i = 0; i < $scope.data.length; i++) {
    $scope.data[i].selectedTab = $scope.data[i].tab[$scope.data[i].tab.length - 1];
  }

  $scope.setSelectedTab = function (node, tab) {
    tab.selectedTab = node;
  };
});

.active {
  color: red;
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
  <div ng-repeat="obj in data">
    <ul class="nav nav-tabs">
      <li ng-class="{ active: obj1[0] && obj.selectedTab == obj1 }" ng-repeat="obj1 in obj.tab track by $index">
        <a href ng-click="setSelectedTab(obj1, obj)">{{ $index }} </a>
      </li>
    </ul>
    <div class="tab-content" ng-repeat="tab in obj.selectedTab track by $index">
      ID: {{tab.id}}<br>
      Status : {{tab.status}}
    </div>
  </div>
</div>
