小編這次要給大家分享的是Vue如何實現圖片輪播組件，文章內容豐富，感興趣的小伙伴可以來了解一下，希望大家閱讀完這篇文章之后能夠有所收獲。
1、先看效果：
熟悉的圖片輪播，只要是個網站，百分之90以上會有個圖片輪播。我認為使用圖片輪播。
第一可以給人以一種美觀的感受，而不會顯得網站那么呆板，
第二可以增加顯示內容，同樣的區域可以顯示更多內容。
2、每學一個新東西 ，圖片輪播都是很好的練手案例，而且，也很實用。
3、基本要求：頁面加載，自動播放。鼠標懸停，停止播放。鼠標離開，繼續播放
點擊左右箭頭切換上一張，下一張圖片。
下方小圓點顯示當前位第幾張圖片。
4、使用Vue實現
5、示例代碼
結構html：
<template>

<div class="window" @mouseover="stop" @mouseleave="play">
<ul class="container" :>
<li>
<img : :src="sliders[sliders.length - 1].img" >
</li>
<li v-for="(item, index) in sliders" :key="index">

<img : :src="sliders[0].img" >
