vue無限輪播插件代碼實例

更新時間：2019年05月10日 11:36:45 作者：UNDERCOVERj

這篇文章主要介紹了vue無限輪播插件，文中通過示例代碼介紹的非常詳細，對大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價值，需要的朋友們下面隨著小編來一起學(xué)習(xí)學(xué)習(xí)吧

思路：

要實現(xiàn)無限輪播，需要在輪播圖前后各加一張圖片，加在前面的是輪播圖的最后一張圖片（重復(fù)的），加在后面的是輪播圖的第一張圖片（重復(fù)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來控制滑動，當(dāng)順向到達alt為4的圖片時，下一張滑到第六張圖片，alt為1，同時改變index為1.然后立即將left移到第二張圖片，alt為1那張。這樣就不會被察覺

好了，貼代碼
