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:

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
