本文实例为大家分享了JavaScript实现原型封装轮播图的具体代码，供大家参考，具体内容如下

只要用dom元素调用这个方法，传一个数组进去，里面放的是图片的路径。

<!DOCTYPE html>
<html lang="en">

<head>
 <meta charset="UTF-8">
 <meta name="viewport" content="width=device-width, initial-scale=1.0">

 <style>
 * {
  padding: 0px;
  margin: 0px;
  list-style: none;
 }

 .leftBtn {
  position: absolute;
  width: 30px;
  height: 30px;
  color: black;
  background-color: cyan;
  top: 50%;
  margin-top: -15px;
  line-height: 30px;
  text-align: center;
  opacity: 0.6;
  cursor: pointer;
  left: 10px;
 }

 .rightBtn {
  position: absolute;
  width: 30px;
  height: 30px;
  color: black;
  background-color: cyan;
  top: 50%;
  margin-top: -15px;
  line-height: 30px;
  text-align: center;
  opacity: 0.6;
  cursor: pointer;
  right: 10px;
 }

 .slider {
  position: absolute;
  bottom: 20px;
  width: 100%;
  text-align: center;
  cursor: pointer;
 }

 .slider span {
  display: inline-block;
  width: 8px;
  height: 8px;
  background-color: darkgray;
  border-radius: 50%;
  margin-left: 10px;
 }

 .slider .active {
  background-color: #f40;
 }
 </style>
</head>

<body>
 <div class="div"></div>
 <div id="div"></div>
 <script>

 var div = document.getElementsByClassName('div')[0]
 var oDiv = document.getElementById('div')
 // var arr = ['./tp copy/decade.jpg', './tp copy/decad.jpg', './tp copy/tp.jpg']
 HTMLDivElement.prototype.createTurnPage = function (arr) {
  var arr = (typeof arr != "object") "opacity") {
   cur = parseFloat(getStyle(dom, attr)) * 100;
   } else {
   cur = parseInt(getStyle(dom, attr));
   }
   speed = (attrObj[attr] - cur) / 7;
   speed = speed < 0 "opacity") {
   dom.style.opacity = (speed + cur) / 100;
   } else {
   dom.style[attr] = speed + cur + "px";
   }
   if (cur != attrObj[attr]) {
   stop = false;
   }
  }
  if (stop) {
   clearInterval(dom.timer);
   typeof callback == "function" && callback();
  }
  }, 20);
 }

 </script>
</body>

</html>
