如何使用AngularJS检索所有选中项的列表？

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.7.9/angular.min.js"></script>

<div ng-app="myApp" ng-controller="myCtrl">
  <input type="checkbox" ng-model="selectedItems[0]" ng-change="updateSelectedItems()"> Item 1
  <input type="checkbox" ng-model="selectedItems[1]" ng-change="updateSelectedItems()"> Item 2
  <input type="checkbox" ng-model="selectedItems[2]" ng-change="updateSelectedItems()"> Item 3
</div>

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
  $scope.selectedItems = [];
  
  $scope.updateSelectedItems = function() {
    var selectedList = [];
    for (var i = 0; i < $scope.selectedItems.length; i++) {
      if ($scope.selectedItems[i]) {
        selectedList.push("Item " + (i+1));
      }
    }
    console.log(selectedList);
  };
});
