javascript - 试图让我的照片幻灯片不断循环播放所有照片

我的网站在标题下方的其中一个部分中有照片幻灯片。当幻灯片播放到第三张照片时停止。我想知道如何将第三张照片转换回第一张照片，然后在所有照片中使用相同的动画继续循环？动画是下一张照片从当前照片的右侧滑入。我的代码如下。

最佳答案

添加一个名为 .no_trans 的 css 类，它将禁用转换。该类将具有以下规则

.no_trans{
  transition:none !important;
    -webkit-transition:none !important;
    -moz-transition:none !important;
    -ms-transition:none !important;
    -o-transition:none !important;
}

当计数器大于号时。您禁用的图像删除过渡类并反转图像的位置(这将很快)

然后计数器以编号开始。小于号自您将其重置为 0 后的元素数量

进程重启

.no_trans {
  transition: none !important;
  -webkit-transition: none !important;
  -moz-transition: none !important;
  -ms-transition: none !important;
  -o-transition: none !important;
}
