swiper使用方法：
1.首先加载插件，需要用到的文件有swiper-bundle.min.js和swiper-bundle.min.css文件，不同[Swiper版本]用到的文件名略有不同。
<!DOCTYPE html>
<html>
<head>
...
<link rel="stylesheet" href="dist/css/**swiper-bundle.min.css**">
</head>
<body>
...
<script src="dist/js/**swiper-bundle.min.js**"></script> ...
</body>
</html>
2.添加HTML内容。Swiper7的默认容器是'.swiper'，Swiper6之前是'.swiper-container'。
<div class="swiper">
<div class="swiper-wrapper">
<div class="swiper-slide">Slide 1</div>
<div class="swiper-slide">Slide 2</div>
<div class="swiper-slide">Slide 3</div>
</div>
<!-- 如果需要分页器 -->
<div class="swiper-pagination"></div>
<!-- 如果需要导航按钮 -->
<div class="swiper-button-prev"></div>
<div class="swiper-button-next"></div>
<!-- 如果需要滚动条 -->
<div class="swiper-scrollbar"></div>
</div>
3.你可能想要给Swiper定义一个大小，当然不要也行。
.swiper { width: 600px; height: 300px; }
4.初始化Swiper。
<script>
var mySwiper = new Swiper ('.swiper', {
direction: 'vertical',
loop: true,
pagination: {
el: '.swiper-pagination',
},
navigation: { nextEl: '.swiper-button-next',
prevEl: '.swiper-button-prev',
},
scrollbar: {
el: '.swiper-scrollbar',
},
})
</script>
