如何使用angular.fromJson()从ng-repeat获取对象

<div ng-repeat="item in items">
  <p>{{ item.name }}</p>
  <p>{{ item.age }}</p>
</div>

$scope.items = [
  { name: 'John', age: 25 },
  { name: 'Jane', age: 30 },
  { name: 'Bob', age: 35 }
];

$scope.getObject = function(index) {
  var jsonString = angular.toJson($scope.items[index]);
  var object = angular.fromJson(jsonString);
  return object;
};

<div ng-repeat="item in items">
  <p>{{ item.name }}</p>
  <p>{{ item.age }}</p>
  <button ng-click="selectedObject = getObject($index)">Get Object</button>
</div>

<div ng-if="selectedObject">
  <p>Selected Object:</p>
  <p>Name: {{ selectedObject.name }}</p>
  <p>Age: {{ selectedObject.age }}</p>
</div>
