因为我的项目的非凡状况,所以须要手动封装一个轮播图,大抵步骤:

  • 筹备一个Hz-carousel组件根底布局并全局注册
  • 筹备home-banner组件，应用Hz-carousel组件，再首页注册应用。
  • 深度作用选择器笼罩Hz-carousel组件的默认款式

上面是具体步骤:

第一步:

当初SRC下的components文件夹中创立一个专门为我的项目封装组件的文件夹,以便好治理.

例如:library/Hz-carousel.vue
轮播图根底构造代码

<template>  <div class='Hz-carousel'>    <ul class="carousel-body">      <li class="carousel-item fade">        <RouterLink to="/">          <img src="http://yjy-xxxxxx-dev.oss-cn-beijing.aliyuncs.com/picture/2021-04-15/1ba86bcc-ae71-42a3-bc3e-37b662f7f07e.jpg" alt="">        </RouterLink>      </li>    </ul>    <a href="javascript:;" class="carousel-btn prev"><i class="iconfont icon-angle-left"></i></a>    <a href="javascript:;" class="carousel-btn next"><i class="iconfont icon-angle-right"></i></a>    <div class="carousel-indicator">      <span v-for="i in 5" :key="i"></span>    </div>  </div></template><script>export default {  name: 'HzCarousel'}</script><style scoped lang="less">.Hz-carousel{  width: 100%;  height: 100%;  min-width: 300px;  min-height: 150px;  position: relative;  .carousel{    &-body {      width: 100%;      height: 100%;    }    &-item {      width: 100%;      height: 100%;      position: absolute;      left: 0;      top: 0;      opacity: 0;      transition: opacity 0.5s linear;      &.fade {        opacity: 1;        z-index: 1;      }      img {        width: 100%;        height: 100%;      }    }    &-indicator {      position: absolute;      left: 0;      bottom: 20px;      z-index: 2;      width: 100%;      text-align: center;      span {        display: inline-block;        width: 12px;        height: 12px;        background: rgba(0,0,0,0.2);        border-radius: 50%;        cursor: pointer;        ~ span {          margin-left: 12px;        }        &.active {          background:  #fff;        }      }    }    &-btn {      width: 44px;      height: 44px;      background: rgba(0,0,0,.2);      color: #fff;      border-radius: 50%;      position: absolute;      top: 228px;      z-index: 2;      text-align: center;      line-height: 44px;      opacity: 0;      transition: all 0.5s;      &.prev{        left: 20px;      }      &.next{        right: 20px;      }    }  }  &:hover {    .carousel-btn {      opacity: 1;    }  }}</style>

**全局注册轮播图

首页广告组件根底构造 src/views/home/components/home-banner.vue

首页应用广告组件
