2 制作成组件
<!DOCTYPE html>

<meta charset="UTF-8">

<link rel="stylesheet" href="https://unpkg.com/swiper/swiper-bundle.css">
<script src="https://unpkg.com/swiper/swiper-bundle.js"></script>
<script src="https://cdn.bootcdn.net/ajax/libs/vue/2.6.12/vue.min.js"></script>
<style>
.swiper-container {
width: 600px;
height: 200px;
}
</style>
</head>
<body>
<div id="box">
<swipper>
<div class="swiper-wrapper">
<div class="swiper-slide" v-for="data in dataList1"><h1 style="text-align: center">{{data}}</h1></div>
</div>
</swipper>
<swipper>
<div class="swiper-wrapper">
<div class="swiper-slide" v-for="data in dataList2"><h1 style="text-align: center">{{data}}</h1></div>
</div>
</swipper>
</div>
</body>
<script>
Vue.component('swipper', {
template: `
<div>
<div class="swiper-container">
<slot></slot>
<div class="swiper-pagination"></div>
</div>
</div>
`, // <slot> 为插槽
// 每次只要有数据更新都会执行该代码，会耗费资源。而我们需求是只需要该部件的数据更新再执行。
// 代表可更新
// 在mouted中，执行函数是异步的，所以在加载数据的时候有了IO，就会先加载swiper，这时swiper没有了数据显示，所以需要把组件放在updated，这样保证了加载组件之前数据已经加载好了。
updated() {
let mySwiper = new Swiper('.swiper-container', {
direction: 'horizontal', // 垂直切换选项
loop: true, // 循环模式选项
// 如果需要分页器
pagination: {
el: '.swiper-pagination',
},
})
}
})
let vm = new Vue({
el: '#box',
data: {
dataList1: [],
dataList2: []
},
mounted() {
setTimeout(() => {
this.dataList1 = ['11111', '22222', '33333']
this.dataList2 = ['66666', '77777', '88888']
}, 3000)
},
})
