自己模仿JQ插件的写法写了一个循环滚动列表插件,支持自定义上、下、左、右四个方向,支持平滑滚动或者间断滚动两种方式,都是通过参数设置。JQ里面有些重复的地方,暂时没想到更好的方法去精简。不过效果还是可以的,如下(效果图上传后都加速了,实际效果比这个要慢很多):

多种JQuery循环滚动文字图片效果代码

html代码如下:

<!doctype html>
<html lang="zh-cn">
<head>
<meta charset="utf-8">
<title>循环滚动列表</title>
<link href="css/style.css" rel="stylesheet"/>
<script src="/UploadFiles/2021-04-02/jquery-1.9.1.min.js">

css样式如下:

@charset "utf-8";

   function(){
   fnDown = setInterval(function(){downMoving()}, o.interval);
   }
  );
  fnDown = setInterval(function(){downMoving()}, o.interval);
  };
 });
 };
})(jQuery);

兼容到IE6+,jq库用1.7+的都没问题 。
