html，js和css中的图像滑块[关闭]

Question

我想在我的html页面中有一个图像滑块，它应该是自动的，它应该有点来表示当前幻灯片，这些点是否可点击无关紧要。它应该有标题文本（响应无关紧要）

在滑块左侧和右侧有手动控制很好，另一件事是滑块上的幻灯片动画不应该褪色或其他东西。

如果任何人可以共享一些可以满足要求的体面库（带演示部分）

谢谢

如果您正在寻找自定义滑块，我推荐这个。

HTML

<!-- Slideshow container -->
<div class="slideshow-container">
<!-- Full-width images with number and caption text -->
<div class="mySlides">
<div class="numbertext">1 / 3</div>
<img src="img1.jpg" style="width:100%"><!--add your image here-->
<div class="text">Caption Text</div>
</div>
<div class="mySlides">
<div class="numbertext">2 / 3</div>
<img src="img2.jpg" style="width:100%"><!--add your image here-->
<div class="text">Caption Two</div>
</div>
<div class="mySlides">
<div class="numbertext">3 / 3</div>
<img src="img3.jpg" style="width:100%"><!--add your image here-->
<div class="text">Caption Three</div>
</div>
<!-- Next and previous buttons -->
<a class="prev" onclick="plusSlides(-1)">&#10094;</a>
<a class="next" onclick="plusSlides(1)">&#10095;</a>
</div>
<br>
 <!-- The dots/circles -->
 <div style="text-align:center">
 <span class="dot" onclick="currentSlide(1)"></span> 
 <span class="dot" onclick="currentSlide(2)"></span> 
 <span class="dot" onclick="currentSlide(3)"></span> 
 </div>

CSS

/* Slideshow container */
.slideshow-container {
   max-width: 1000px;
   position: relative;
   margin: auto;
  }

/* Hide the images by default */
  .mySlides {
     display: none;
   }

    /* Next & previous buttons */
   .prev, .next {
       cursor: pointer;
       position: absolute;
       top: 50%;
       width: auto;
       margin-top: -22px;
       padding: 16px;
       color: white;
       font-weight: bold;
       font-size: 18px;
       transition: 0.6s ease;
       border-radius: 0 3px 3px 0;
       user-select: none;
    }

   /* Position the "next button" to the right */
    .next {
       right: 0;
       border-radius: 3px 0 0 3px;
     }

     /* On hover, add a black background color with a little bit see-through 
     */
       .prev:hover, .next:hover {
        background-color: rgba(0,0,0,0.8);
       }

       /* Caption text */
       .text {
          color: #f2f2f2;
          font-size: 15px;
          padding: 8px 12px;
          position: absolute;
          bottom: 8px;
          width: 100%;
          text-align: center;
       }

       /* Number text (1/3 etc) */
       .numbertext {
            color: #f2f2f2;
            font-size: 12px;
            padding: 8px 12px;
            position: absolute;
            top: 0;
         }

       /* The dots/bullets/indicators */
         .dot {
           cursor: pointer;
           height: 15px;
           width: 15px;
           margin: 0 2px;
           background-color: #bbb;
           border-radius: 50%;
           display: inline-block;
           transition: background-color 0.6s ease;
        }

        .active, .dot:hover {
            background-color: #717171;
         }

脚本

        var slideIndex = 1;
        showSlides(slideIndex);

       // Next/previous controls
        function plusSlides(n) {
             showSlides(slideIndex += n);
          }

          // Thumbnail image controls
             function currentSlide(n) {
                 showSlides(slideIndex = n);
               }

           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";
       }

如果在幻灯片中需要更改淡入淡出效果，请使用此类而不是mySlides“淡化”。

.fade{
    -webkit-animation-name: fade;
     -webkit-animation-duration: 1.5s;
     animation-name: fade;
     animation-duration: 1.5s;
     }
     @-webkit-keyframes fade {
       from {opacity: .4} 
       to {opacity: 1}
     }

     @keyframes fade {
       from {opacity: .4} 
       to {opacity: 1}
      }

谢谢！

您可以使用Bootstrap 4，它将帮助您节省时间和代码，因此您只需要编写正确的calss名称。 EX：qazxsw poi以下是入门文档的链接：qazxsw poi
