我如何在angularjs中访问深度嵌套的json对象

在这里，我想从第一页上的Json数据访问顶级市场详细信息，尽管我无法访问次级市场详细信息，但我能够访问。我想在下一页上显示次级市场名称。

$scope.myData = {
  "market": [{
    "mid": 3,
    "mname": "mark1",
    "submarket": [{
      "id": 20,
      "name": "val1"
    }, {
      "id": 24,
      "name": "val2",
      "submarket": [{
        "id": 26,
        "name": "val21"
      }]
    }]
    "market": [{
      "mid": 4,
      "name": "mark1.1",
      "submarket": [{....
      }]
    }]
  }, {
    "mid": 6,
    "mname": "mark2",
  }]
};

$scope.markname = []; /*stores top level markets*/
angular.forEach($scope.myData.market, function(org) {
  $scope.markname.push(org)
}) /*works fine and has the details of market (mid:3 and mid:6)*/

$scope.submark = [];
angular.forEach($scope.markname.submarket, function(sorg) {
  $scope.submark.push(sorg)
}) /*doesn't store anything*/

米歇尔

它应该是：

  $scope.submark = [];
  angular.forEach($scope.markname, function(sorg) {
    angular.forEach(sorg.submarket, function(subsorg) {
      $scope.submark.push(subsorg)
    });
  });
