vue无限轮播插件代码实例
UNDERCOVERj 人气:0思路：
要实现无限轮播，需要在轮播图前后各加一张图片，加在前面的是轮播图的最后一张图片（重复的），加在后面的是轮播图的第一张图片（重复的）。例：
<div class="wrapper-content">
<img class="wrapper-content_img" alt="4" src="img/4.jpg"/>
<img class="wrapper-content_img" alt="1" src="img/1.jpg"/>
<img class="wrapper-content_img" alt="2" src="img/2.jpg"/>
<img class="wrapper-content_img" alt="3" src="img/3.jpg" />
<img class="wrapper-content_img" alt="4" src="img/4.jpg" />
<img class="wrapper-content_img" alt="1" src="img/1.jpg" />
</div>
然后再用left来控制滑动，当顺向到达alt为4的图片时，下一张滑到第六张图片，alt为1，同时改变index为1.然后立即将left移到第二张图片，alt为1那张。这样就不会被察觉
好了，贴代码
