如何使手风琴活动项目可点击

Question

在过去几个小时的反复试验之后，我意识到我真的应该学习 jQuery 基础知识的课程。有人可以帮我解答一个简单的问题吗？

我将this 手风琴放入页面，但我希望活动面板能够单击以关闭。有什么简单的方法可以让这成为可能吗？

(function($) {

  //Hide all panels
  var allPanels = $('.accordion > dd').hide();

  //Show first panel
  $('.accordion > dd:first-of-type').show();

  //Add active class to first panel 
  $('.accordion > dt:first-of-type').addClass('accordion-active');

  //Handle click function
  jQuery('.accordion > dt').on('click', function() {

    //this clicked panel
    $this = $(this);

    //the target panel content
    $target = $this.next();

    //Only toggle non-displayed 
    if(!$this.hasClass('accordion-active')){

      //slide up any open panels and remove active class
      $this.parent().children('dd').slideUp();

      //remove any active class
      jQuery('.accordion > dt').removeClass('accordion-active');

      //add active class
      $this.addClass('accordion-active');

      //slide down target panel
      $target.addClass('active').slideDown();

    }

    return false;
  });

})(jQuery);

试试：

  jQuery('.accordion > dt').on('click', function() {
      //this clicked panel
      var $this = $(this), 
          $target = $this.next(); 

      //slide up any open panels and remove active class
      $this.parent().children('dd').not($target).slideUp(); //Slide Up everything but the target one

      //remove any active class
      jQuery('.accordion > dt').removeClass('accordion-active');
      //add active class
      $this.addClass('accordion-active');
      //slide down target panel
      $target.addClass('active').slideToggle();

    return false;
  });

实际上您可以将其简化为：

 jQuery('.accordion > dt').on('click', function () {
        var $this = $(this) ,
            $target = $this.next();

        $('.accordion > dt.accordion-active').not($this.toggleClass('accordion-active')).removeClass('accordion-active');

        $this.siblings('dd').not($target.addClass('active').slideToggle()).slideUp();

        return false;
    });
