jquery - 打开和关闭容器(div)

我之前使用过jQuery，但最近我不得不在HTML中添加一些div。我试图通过单击按钮discussionContainer打开和关闭replyButton。任何帮助都会很棒。

我将在此处通过replyButton进行ng单击时，我将通过一个id请求从我的数据库中获取内容的http请求，我可以在Angularjs中这样做吗？也许除了jQuery和Angularjs之外还有其他一些想法/建议？在页面加载时，discussionContainer将关闭。

$(document).on("click", ".replyButton", function() {
  $(this).parent('.forQuestions').find(".discussionContainer").slideToggle(300);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<li class="question">
  <div class="forQuestion">
    <div class="cardBody">
      {{answer.aContent}}
    </div>
    <div class="cardFooter">
      <div class="col-xs-4 footer1">
        <button class="replyButton">Reply</button>
      </div>
      <div class="col-xs-4 footer2">
        <i class="fa fa-trash" aria-hidden="true" ng-click="controller.deleteAnswer(answer._id)"></i>
        <i class="fa fa-pencil" aria-hidden="true" ng-click="controller.showEditAnswerModal(answer)"></i>
      </div>
      <div class="col-xs-4 footer3">
        {{answer.aDate | date: 'medium'}}
      </div>
    </div>
    <div class="discussionContainer">
      <ul>
        <li>comment1</li>
        <li>comment2</li>
      </ul>
      <div class="newComment">
        <textarea rows="2" cols="30" placeholder="New comment"></textarea>
        <button type="button" name="button">Comment</button>
      </div>
    </div>
  </div>
</li>

最佳答案

您的代码存在的问题是：

1-.parent()仅在DOM树上移动单个级别

2--您没有类forQuestions的元素，正确的类是forQuestion末尾没有s的..因此您需要使用.closest('.forQuestion')

演示版

$(document).on("click", ".replyButton", function() {
  $(this).closest('.forQuestion').find(".discussionContainer").slideToggle(300);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<li class="question">
  <div class="forQuestion">
    <div class="cardBody">
      {{answer.aContent}}
    </div>
    <div class="cardFooter">
      <div class="col-xs-4 footer1">
        <button class="replyButton">Reply</button>
      </div>
      <div class="col-xs-4 footer2">
        <i class="fa fa-trash" aria-hidden="true" ng-click="controller.deleteAnswer(answer._id)"></i>
        <i class="fa fa-pencil" aria-hidden="true" ng-click="controller.showEditAnswerModal(answer)"></i>
      </div>
      <div class="col-xs-4 footer3">
        {{answer.aDate | date: 'medium'}}
      </div>
    </div>
    <div class="discussionContainer">
      <ul>
        <li>comment1</li>
        <li>comment2</li>
      </ul>
      <div class="newComment">
        <textarea rows="2" cols="30" placeholder="New comment"></textarea>
        <button type="button" name="button">Comment</button>
      </div>
    </div>
  </div>
</li>
