Question

我用html / css创建了一个图库，单击箭头一次可滚动4张照片，我希望它滚动一张。我结合起来，我很好:) 我希望每个元素都分开，每张照片。只需使代码更干净:)如果您有任何帮助，我将不胜感激。

您有什么想法吗？抱歉，我正确添加了延迟代码，但是我是第一次添加它：）

$(".gallery-slider li").each(function(e) {
  if (e != 0)
    $(this).hide();
});

$("#next").click(function() {
  if ($(".gallery-slider li:visible").next().length != 0)
    $(".gallery-slider li:visible").next().show().prev().hide();
  else {
    $(".gallery-slider li:visible").hide();
    $(".gallery-slider li:first").show();
  }
  return false;
});

$("#prev").click(function() {
  if ($(".gallery-slider li:visible").prev().length != 0)
    $(".gallery-slider li:visible").prev().show().next().hide();
  else {
    $(".gallery-slider li:visible").hide();
    $(".gallery-slider li:last").show();

  }
  return false;
});

您可以尝试与此类似的操作，因为这一次只能显示一张图像：

<html>
<title>Example</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="https://www.w3schools.com/w3css/4/w3.css">
<body>

<h2 class="w3-center">Manual Slideshow</h2>

<div class="w3-content w3-display-container">
  <img class="mySlides" src="img_snowtops.jpg" style="width:100%">
  <img class="mySlides" src="img_lights.jpg" style="width:100%">
  <img class="mySlides" src="img_mountains.jpg" style="width:100%">
  <img class="mySlides" src="img_forest.jpg" style="width:100%">

  <button class="w3-button w3-black w3-display-left" onclick="plusDivs(-1)">&#10094;</button>
  <button class="w3-button w3-black w3-display-right" onclick="plusDivs(1)">&#10095;</button>
</div>

<script>
var slideIndex = 1;
showDivs(slideIndex);

function plusDivs(n) {
  showDivs(slideIndex += n);
}

function showDivs(n) {
  var i;
  var x = document.getElementsByClassName("mySlides");
  if (n > x.length) {slideIndex = 1}    
  if (n < 1) {slideIndex = x.length}
  for (i = 0; i < x.length; i++) {
     x[i].style.display = "none";  
  }
  x[slideIndex-1].style.display = "block";  
}
</script>
