.controller('MyCtrl', function($scope) {
   var stores = ['apple', 'samsung', 'micromax' ,'nokia', 'sony'];
   
  $scope.groups = [];
  for (var i=0; i<stores.length; i++) {
    $scope.groups[i] = {

      items: [],
      show: false
    };
     
    for (var j=0; j<5; j++) {

    }
  }
  
  /*
   * if given group is the selected group, deselect it
   * else, select the given group

  $scope.toggleGroup = function(group) {
    group.show = !group.show;

  $scope.isGroupShown = function(group) {
    return group.show;
  };
  
});

Answer 1

控制器：

 angular
  .module('ionicApp', ['ionic'])
  .controller('MyCtrl', function ($scope) {
    var stores = ['apple', 'samsung', 'micromax', 'nokia', 'sony'];

    $scope.groups = [];
    for (var i = 0; i < stores.length; i++) {
      $scope.groups.push({
        name: stores[i],

        items: [],
        show: false
      });

      for (var j = 0; j < 5; j++) {
        $scope.groups[i].items.push(j);
      }
    }

    /*
     * if given group is the selected group, deselect it
     * else, select the given group
     */
    $scope.toggleGroup = function (group) {
      group.show = !group.show;
    };
    $scope.isGroupShown = function (group) {
      return group.show;
    };

  });

$ scope.groups将导致您如下所示

如果我理解你的问题是正确的，那么你不需要第二个for循环。

在你的js文件中，你有

for (var j=0; j<5; j++) {
  $scope.groups[i].items.push(j);
}

我认为你需要的只是

$scope.group[i].items.push(i);

如何使用angularjs在循环中推送数组值？
