我正在尝试制作幻灯片,但是当幻灯片移至下一张(或上一张)图像时,背景上没有任何内容。
我希望您将看到的图像出现在您所看到的图像的后面,例如当您洗牌时。
另外,当您单击向右或向左箭头以匹配其运动时,我希望具有不同的动画。
这是我现在正在使用的代码:

}
function showSlides(n) {
var i;
var slides = document.getElementsByClassName("mySlides");
var dots = document.getElementsByClassName("dot");
if (n > slides.length) {slideIndex = 1}
if (n < 1) {slideIndex = slides.length}
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
for (i = 0; i < dots.length; i++) {
dots[i].className = dots[i].className.replace(" active", "");
}
slides[slideIndex-1].style.display = "block";
dots[slideIndex-1].className += " active";
}
</script>
</body>

谢谢!
最佳答案
问题是您正在使用JavaScript和CSS隐藏除当前幻灯片以外的所有内容。
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
.mySlides {display: none}
您将需要删除它,但是要更改幻灯片的z-index,以便当前幻灯片位于顶部,同时添加slideInRight / slideInLeft类。您还需要将幻灯片绝对定位在容器中,以便它们占据相同的位置。
