Javascript 使用类从一个标记中双击事件

当我点击旁白时，它工作正常，但当我在旁白上添加活动类，然后再次点击时，它不工作。实际上，我想在活动模式下单击侧边时切换箭头

<article class="headings">
    <p class="link">Link</p>
    <aside class="date">
        Date 
        <span class="fa fa-caret-down"></span>

您可能需要创建一个动态/委托点击功能：

$(document).on('.click','.headings aside',function() {
    $('.headings aside').removeClass('active');
    $(this).addClass('active')
    $('.headings aside').children('span.fa-caret-up').removeClass('fa-caret-up').addClass('fa-caret-down');
    $(this).children('span').removeClass('fa-caret-down').addClass('fa-caret-up');
});

$(document).on('.click','.headings aside.active', function() {
    $(this).children('span').removeClass('fa-caret-down').addClass('fa-caret-up');
});

您可能需要将fa插入符号向下翻转fa插入符号向上，以满足您的需要

$('.headings aside').click(function() {
   $(this).toggleClass("active")
   $(this).children('span').toggleClass('fa-caret-down fa-caret-up');
});
