如何使用angularJS在同一页中追加条目，而不使用数组来存储先前的条目

<div ng-repeat="item in items">
  {{ item }}
</div>

<input type="text" ng-model="newItem">

<button ng-click="addItem()">Add Item</button>

angular.module('myApp', [])
  .controller('myController', function($scope) {
    $scope.items = [];

    $scope.addItem = function() {
      $scope.items.push($scope.newItem);
      $scope.newItem = ''; // 清空输入框
    };
  });

<div ng-app="myApp" ng-controller="myController">
  <!-- HTML代码 -->
</div>
