angularJS，将复选框列表展平为CSV

<div ng-app="myApp" ng-controller="myCtrl">
  <label ng-repeat="item in items">
    <input type="checkbox" ng-model="item.selected">{{ item.name }}
  </label>
</div>

angular.module('myApp', [])
  .controller('myCtrl', function($scope) {
    $scope.items = [
      { name: 'Item 1', selected: false },
      { name: 'Item 2', selected: true },
      { name: 'Item 3', selected: true },
      { name: 'Item 4', selected: false }
    ];

    $scope.flattenList = function() {
      var selectedItems = [];
      angular.forEach($scope.items, function(item) {
        if (item.selected) {
          selectedItems.push(item.name);
        }
      });
      $scope.csv = selectedItems.join(', ');
    };
  });

<div ng-app="myApp" ng-controller="myCtrl">
  <label ng-repeat="item in items">
    <input type="checkbox" ng-model="item.selected">{{ item.name }}
  </label>
  <button ng-click="flattenList()">展平为CSV</button>
  <p>CSV: {{ csv }}</p>
</div>
