Angular.js 1.4.2 CSS動畫不適用於ng-show

Question

我正在嘗試在按鈕上添加CSS動畫，因此數據不會淡入或淡出。 但是當前單擊按鈕只是立即將類更改為ng-hide，或將其更改為ng-hide，因此動畫永遠不會被調用。 我正在嘗試根據Angular.js網站上給出的示例進行工作： https ：//docs.angularjs.org/api/ng/directive/ngShow

網站上提供的工作代碼編碼器位於此處： http ://plnkr.co/edit/2ZJ9pdUq1tXLbDLuShEV?p=preview

我的代碼（出於某種原因無法進行動畫處理）位於 ： http : //plnkr.co/edit/vnvVUciM5qMVyqzv2nL0?p=preview

<body ng-app="assignment" ng-controller="AssignmentController as assignment">
  <button type="button" ng-click="current_question_id = 0">0</button>
  <button type="button" ng-click="current_question_id = 1">1</button>

  <div class="panel-body" id="form_content">
    <div ng-repeat="question in questions" ng-show="question.id == current_question_id" class="question-container">
      <div class="position-center">
        <div class="form-horizontal">
          <div class="form-group">
            <label for="question_question_{{ question.id }}" class="col-lg-2 col-sm-2 control-label">Question</label>
            <div class="col-lg-10">
              <input type="text" id="question_question_{{ question.id }}" name="questions[][question]" placeholder="Question" class="form-control" ng-value="question.question">
              <p class="help-block">{{ question.type }}</p>
            </div>
          </div>
        </div>
      </div>
    </div>
  </div>
</body>

CSS：

.question-container {
  line-height: 20px;
  opacity: 1;
  padding: 10px;
}

.question-container.ng-hide-add.ng-hide-add-active,
.question-container:not(.ng-hide) {
  -o-transition: all linear 0.5s;
  -moz-transition: all linear 0.5s;
  -webkit-transition: all linear 0.5s;
  transition: all linear 0.5s;
}

.question-container.ng-hide {
  line-height: 0;
  opacity: 0;
  padding: 0 10px;
}

JS：

(function(){
  var app = angular.module('assignment', []);
  app.controller('AssignmentController', function($scope, $http){
    $scope.questions = [{id: 0, question: "What is the capital of Greenland?", type: "Short Answer"},
    {id: 1, question: "Wtf is going on?", type: "Long Answer"}];
  });
})();

似乎在我的代碼中，由於某種原因，該元素從未獲得ng-hide-add或ng-hide-remove類。 有任何想法嗎？ 謝謝！

您需要將ngAnimate注入應用程序的模塊中：

(function(){
  var app = angular.module('assignment', ['ngAnimate']);
  app.controller('AssignmentController', function($scope, $http){
    $scope.questions = [{id: 0, question: "What is the capital of Greenland?", type: "Short Answer"},
    {id: 1, question: "Wtf is going on?", type: "Long Answer"}];
  });
})();
