Question

我有一些常见问题解答，包括问题和解答。在document上，所有答案都被隐藏（display: none）。

1。。在点击提问时，答案将slideDown。

2。。在单击另一个问题时，另一个答案将slideDown，而当前答案将slideUp

现在我需要，页面上始终显示至少一个答案（显示答案时，当前答案不会slideToggle，我该如何实现呢？（当然使用JQuery库）

$(function () {
    let answers = $('.answer');

    $('.faq .ask').on('click', slideAnswer);
    
    function slideAnswer() {
        let currentAnswer = $(this).next();
        currentAnswer.addClass('active');
        answers.not(currentAnswer).slideUp(500).removeClass('active');
        $(this).next().stop(true).slideToggle(500, function () {
            if (currentAnswer.hasClass('active')) {
                currentAnswer.stop(true).slideUp;
            }
        });
    }
});

  

.item .ask {
    background: #ccc;
}  

.item .answer {
    border: 1px solid #ccc;
    padding: 10px;
    display: none;
}

<div class="faq">
    <div class="item">
        <div class="ask">1. Some question №1</div>
        <div class="answer">
            <p>Lorem ipsum dolor sit.</p>
        </div>
    </div>
    <div class="item">
        <div class="ask">2. Some question №2</div>
        <div class="answer">
            <p>Lorem ipsum dolor .</p>
        </div>
    </div>
    <div class="item">
        <div class="ask">3. Some question №3</div>
        <div class="answer">
            <p>Lorem ipsum dolor sit .</p>
        </div>
    </div>
</div>

Answer 1

尝试下面的代码

$(function () {
   var answers = $('.answer');
    $('.faq .ask').on('click', function(){
        var currentAnswer = $(this).next('div.answer');
        answers.not(currentAnswer).slideUp(500);
        answers.not(currentAnswer).removeClass('active');
        currentAnswer.stop(true).slideToggle(500);
        currentAnswer.toggleClass('active');
    });
});

Answer 2

您可以简单地向上滑动所有answer部分，而仅向下滑动当前问题的同级答案部分，如下所示：

$(document).on("click",".ask",function(){
    $(".answer").slideUp("500"),$(this).siblings(".answer").slideDown("500");
})

Answer 3

对于您给定的解决方案，我没有做太多改变，只是在.answer类包含.active类的情况下停止了代码。请检查代码段

$(function () {
    let answers = $('.answer');

    $('.faq .ask').on('click', slideAnswer);

    function slideAnswer() {
        let currentAnswer = $(this).next(),
            currentAnswerState = $(this).siblings('.answer');

        if (currentAnswerState.hasClass('active')) {
            return true;
        }

        currentAnswer.addClass('active');
        answers.not(currentAnswer).slideUp(500).removeClass('active');

        $(this).next().stop(true).slideToggle(500, function () {
            currentAnswer.stop(true).slideUp;
        });
    }
});

.item .ask {
    background: #ccc;
}

.item .answer {
    border: 1px solid #ccc;
    padding: 10px;
    display: none;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div class="faq">
  <div class="item">
      <div class="ask">1. Some question №1</div>
      <div class="answer">
          <p>Lorem ipsum dolor sit.</p>
      </div>
  </div>
  <div class="item">
      <div class="ask">2. Some question №2</div>
      <div class="answer">
          <p>Lorem ipsum dolor .</p>
      </div>
  </div>
  <div class="item">
      <div class="ask">3. Some question №3</div>
      <div class="answer">
          <p>Lorem ipsum dolor sit .</p>
      </div>
  </div>
</div>
