Question

我有手风琴箭。实现的目标是在主动式手风琴滑下时改变div类。我唯一的结果是 - 将所有div类从arrow-down更改为arrow-up。如何仅更改活动？

$('.accordion-item').click(function(e) {
    e.preventDefault();

    var $this = $(this);
    var $arrow = $('.accordion-arrow');

    if ($this.next().hasClass('show')) {
        $this.next().removeClass('show');
        $this.next().slideUp(350);
    } else {
        $this.parent().parent().find('li .inner').removeClass('show');
        $this.parent().parent().find('li .inner').slideUp(350);
        $this.next().toggleClass('show');
        $this.next().slideToggle(350);
    }
});

Answer 1

你可以简单地使用toggleClass来从手风琴音乐会改为手风琴音乐会：

$(this).find('.accordion-arrow').toggleClass('accordion-down accordion-up');

您需要在以下内容中添加上一行：

$（＆＃39; .accordion-item＆＃39;）。点击（功能（e）{

事件处理程序。

＆＃13;

$('.accordion-item').click(function(e) {
    e.preventDefault();

    var $this = $(this);
    var $arrow = $('.accordion-arrow');

    if ($this.next().hasClass('show')) {
        $this.next().removeClass('show');
        $this.next().slideUp(350);
    } else {
        $this.parent().parent().find('li .inner').removeClass('show');
        $this.parent().parent().find('li .inner').slideUp(350);
        $this.next().toggleClass('show');
        $this.next().slideToggle(350);
    }
    //
    // added next line
    //
    $(this).find('.accordion-arrow').toggleClass('accordion-down accordion-up');
});

Answer 2

首先，你可以删除类向上箭头并添加向下箭头类，这样它只会显示当前手风琴的箭头，然后使用toggleClass()方法切换到＆amp;向下箭头课。

＆＃13;

$('.accordion-item').click(function(e) {
  e.preventDefault();

  var $this = $(this);
  var $arrow = $('.accordion-arrow');
  var $current = $(this).find(".accordion-arrow");
  $arrow.not($current).removeClass("accordion-up").addClass("accordion-down");
  $current.toggleClass("accordion-up accordion-down");
  if ($this.next().hasClass('show')) {
    $this.next().removeClass('show');
    $this.next().slideUp(350);
  } else {
    $this.parent().parent().find('li .inner').removeClass('show');
    $this.parent().parent().find('li .inner').slideUp(350);
    $this.next().toggleClass('show');
    $this.next().slideToggle(350);
  }
});
