H5响应式开发之响应式轮播图

轮播图

响应式轮播图

轮播图是一个很好页面展示功能。但是如果要实现需要使用Js与jq,比较麻烦,我们学了使用bootstrap插件可以使用内置的样式轻松的制作轮播图。

首先我们创建录播图的内容和指标

<ol>
<li></li>
<li></li>
<li></li>
</ol>
<div>
        <div >
            <img src="https://img.php.cn/upload/course/000/000/004/58195a76b3e4e324.jpg" alt="第一张">
        </div>
        <div>
            <img src="https://img.php.cn/upload/course/000/000/004/58195a9240209277.jpg" alt="第二张">
        </div>
        <div >
            <img src="https://img.php.cn/upload/course/000/000/004/58195abe6d829108.jpg"  alt="第三章">
        </div>
    </div>

内容部分

<a  href="#"></a>
<a  href="#"></a>

轮播导航

接下来我们对着三个部分进行编写

<div id="myCarousel" class="carousel slide">
    <!-- 轮播(Carousel)指标 -->
    <ol class="carousel-indicators">
        <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
        <li data-target="#myCarousel" data-slide-to="1"></li>
        <li data-target="#myCarousel" data-slide-to="2"></li>
    </ol>
    <!-- 轮播(Carousel)项目 -->
    <div class="carousel-inner">
        <div class="item active" style="background: #E2DACF">
            <img src="https://img.php.cn/upload/course/000/000/004/58195a76b3e4e324.jpg" alt="第一张">
        </div>
        <div class="item" style="background: #000000">
            <img src="https://img.php.cn/upload/course/000/000/004/58195a9240209277.jpg" alt="第二张">
        </div>
        <div class="item" style="background: #FEDF85">
            <img src="https://img.php.cn/upload/course/000/000/004/58195abe6d829108.jpg"  alt="第三章">
        </div>
    </div>
    <!-- 轮播(Carousel)导航 -->
    <a class="carousel-control left" href="#myCarousel"
       data-slide="prev">
        <span class="glyphicon glyphicon-chevron-left"></span>
    </a>
    <a class="carousel-control right" href="#myCarousel"
       data-slide="next">
        <span class="glyphicon glyphicon-chevron-right"></span>
    </a>
</div>
</div>

用法

通过 data 属性:使用 data 属性可以很容易控制轮播(Carousel)的位置。

属性 data-slide 接受关键字 prev 或 next,用来改变幻灯片相对于当前位置的位置。使用 data-slide-to 来向轮播传递一个原始滑动索引,data-slide-to="2" 将把滑块移动到一个特定的索引,索引从 0 开始计数。

data-ride="carousel" 属性用于标记轮播在页面加载时就开始动画播放。

这样我们的轮播图就完成了

本章难点

  1. 如何使用bootstrap来完成轮播图

  2. JS的引入与配置
