本文主要分享了 js 实现无缝滚动图的示例代码,具有很好的参考价值,下面跟着小编一起来看下吧
效果如下:
代码如下:
- <!DOCTYPE html>
- <html lang="en">
- <head>
- <meta charset="utf-8">
- <style type = "text/CSS">

- <script type = "text/javascript">
- window.onload = function(){

- function autoAd(){
- leader -=5;
- leader<=-3200?leader = 0:leader;
- ad.style.left = leader +"px";
- }
- //鼠标划入 关闭定时器
- ad.onmouseover = function() {
- clearInterval(timer);
