javascript - 我想用 javascript 创建一个图像滑块

问题描述

实际上我想用java脚本制作一个简单的图像滑块，它会在2秒后自动改变图像

标签： javascripthtmlcss

解决方案

使用引导旋转。它几乎兼容所有浏览器并且易于实现。无需从头开始编码。

使用这些文件将引导程序包含到您的项目中，

//css
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css" integrity="sha384-9gVQ4dYFwwWSjIDZnLEWnxCjeSWFphJiwGPXr1jddIhOegiu1FwO5qRGvFXOdJZ4" crossorigin="anonymous">

//js

使用下面的滑块

<div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">
  <ol class="carousel-indicators">
    <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
    <li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
    <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
  </ol>
  <div class="carousel-inner">
    <div class="carousel-item active">
      <img class="d-block w-100" src=".../800x400?auto=yes&bg=777&fg=555&text=First slide" alt="First slide">
    </div>
    <div class="carousel-item">
      <img class="d-block w-100" src=".../800x400?auto=yes&bg=666&fg=444&text=Second slide" alt="Second slide">
    </div>
    <div class="carousel-item">
      <img class="d-block w-100" src=".../800x400?auto=yes&bg=555&fg=333&text=Third slide" alt="Third slide">
    </div>
  </div>
  <a class="carousel-control-prev" href="#carouselExampleIndicators" role="button" data-slide="prev">
    <span class="carousel-control-prev-icon" aria-hidden="true"></span>
    <span class="sr-only">Previous</span>
  </a>
  <a class="carousel-control-next" href="#carouselExampleIndicators" role="button" data-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>
