JQuery 图像手风琴活动 css

Question

我还没有看到很多手风琴链接到它旁边的图像，而不是正文中的图像，所以决定稍微玩一下。我似乎无法将 css 应用于活动 class，尽管 class 本身发生了变化。 h3 是否需要成为一个按钮才能工作？我只希望活动 class 有一个 - 而不是 + 并应用更深的颜色。任何提示将不胜感激。我认为 JQuery 是正确的，它可能只是我的 css 之类的。这是到目前为止的代码 -

  // Hide all panels
  let panels = $("#services__accordion > .accordion > .accordion__body").hide()

  // Hide all accordion images
      images = $("#accordion__img > img").hide();

  // Show first panel at start
  panels.first().show();

  // Show first accordion image at start
  images.first().show();

  // On click of a panel title

  $("#services__accordion .accordion  h3").click(function() {
    // The panel is not the H3, but its parent.
    let panel = $(this).parent(),
      tabName = panel.attr("tab-name"),
      image = $("#" + tabName + "-img");
    //Slide Up all other panels
    panels.slideUp();
    images.slideUp();

    // Slide Down target panel, and target image.
    panel.find(".accordion__body").slideDown();
    image.slideDown();    

    return false;
  });
});
    
//Add active class
    $(".accordion  h3").on('click', function(){
        $(".accordion  h3").removeClass('active');
        $(this).addClass('active');
    });

和这里的 jsfiddle - https://jsfiddle.net/MarioL/32nv0szw/ 谢谢！

Answer 1

.... I can't seem to get the css to be applied to the active class

发生这种情况是因为您的 css 部分是通用的：

.active:after {
    content: "12";
 }

将其更改为特定的：

#services__accordion h3.active:after {
    content: "12";
}

此外，您可以合并点击事件并使用它在启动时显示感兴趣的面板。

密码是：

let panels = $("#services__accordion > .accordion > .accordion__body").hide()

// Hide all accordion images
images = $("#accordion__img > img").hide();



// On click of a panel title

$("#services__accordion .accordion  h3").click(function () {
    // The panel is not the H3, but its parent.
    let panel = $(this).parent(),
            tabName = panel.attr("tab-name"),
            image = $("#" + tabName + "-img");

    // Slide Up all other panels
    panels.slideUp();
    images.slideUp();

    // Slide Down target panel, and target image.
    panel.find(".accordion__body").slideDown();
    image.slideDown();

    $(".accordion  h3.active").removeClass('active');
    $(this).addClass('active');

    return false;
}).eq(0).trigger('click');
