手风琴需要点击 2 次才能启动 + 图标旋转

Question

我拼凑了一些在我的网站上找到的手风琴常见问题解答代码。我不确定如何通过单击 1 次来扩展标题，因为目前需要 2 次。我还希望图标在 expanding/collapsing 时旋转。目前仅旋转 on/off 悬停。我包括一个简短的例子，说明我目前拥有的东西。

非常感谢任何帮助，谢谢。

  $('.js-question').on('click', function(e) {
    var $answer = $(this).next(),
      actveClass = 'active',
      isActive = $answer.hasClass(actveClass);
    $('.answer').slideUp().addClass(actveClass);
    if (isActive) {
      $answer.toggleClass(actveClass);
      $answer.slideToggle();
    }
  });

Answer 1

您正在向您的函数发送相互矛盾的命令。在这里 $('.answer').slideUp().addClass(actveClass); 您要向上滑动所有答案并将活动 class 添加到所有答案（我相信您想要删除它）。

然后，你问目标答案是否有活动的class（答案显然是肯定的，无论如何，因为你已经将它添加到所有元素之前）。

这个条件 if (isActive) {，即使您之前的代码是正确的，也是完全没有必要的。你可以做什么从除目标答案之外的所有答案中删除活动 class，然后仅切换已点击的答案，你已经在此处定位 $answer = $(this).next().

所以工作代码是：

$('.js-question').on('click', function(e) {
    var $answer = $(this).next(),
      actveClass = 'active';    
    $('.answer').not($answer).slideUp().removeClass(actveClass); /* remove instead of add and apply in every answer except the clicked one*/
    /* remove unnecessary conditional */  
      $answer.toggleClass(actveClass);
      $answer.slideToggle();
  });

更新以使图标正常工作

与 .answer 相同的方法。您从所有按钮中删除活动 class，除了单击的按钮，然后切换单击的按钮 class。

$('.js-question').on('click', function(e) {
  var $answer = $(this).next(),
    actveClass = 'active';
  $('.bracket-button').not($(this)).removeClass(actveClass);
  $('.answer').not($answer).slideUp().removeClass(actveClass);
  $(this).toggleClass(actveClass);
  $answer.toggleClass(actveClass);
  $answer.slideToggle();
});
