Swiper10.1.0图片轮播效果

1、swiper安装10.1.0版本：https://blog.csdn.net/Y1914960928/article/details/132583878

2、swiper使用：

① 模板使用：

② ts中引入组件：

③ 组件使用：

声明

变量配置

样式编写

3、图片显示顺序问题：

4、完整代码：

<template>
  <div class="pic-module">
    <!-- tab以及上传图片按钮 -->
    <div class="pic-module__top">
      <div class="left-box">

6、遇到的问题及解决：

① 分页器不显示：

换版本

本来一开始用的swiper7.4.1，但是分页器一直不出来，元素审查都没有找到对应的代码，所以换了版本。

增加下面的代码

import Swiper, {Navigation, Pagination} from "swiper";
// 新版Swiper默认只导出核心部分，需要如导航、分页等组件的话需要另外导入，并使用Swiper.use()添加
Swiper.use([Navigation, Pagination]);

② 鼠标移入左侧或者右侧的固定区域，上下翻页的按钮进行显示，否则不显示，也不会一起显示：

给上下翻页的按钮套个壳子，然后更改图层的权重
