Angular js set default tab with ng-repeat in array object-CodePudding

I want to show last object of each tab in default tab. Now my interface is like this: tab[0] last object is {"id": 8, "status": 1}, tab[1] last object is {"id": 8, "status": 1} but it is wrong. I want it to look like this: tab[0] last object is {"id": 5, "status": 0}, tab[1]last object is{"id": 8, "status": 1}`.

My json data like this:

[
  {
    "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}
            ]
          ]
  },
];

My 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;
};

My 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>

Can someone please help in identifying what am i doing wrong?

CodePudding user response：

You have to correct your last tab selection logic.

Since selectedTab is specific to each node in your data array, I parsed the array and added a selectedTab property to each data node which holds its first.

Working 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;
}
