Html js轻松实现向上下左右循环滚动代码,代码如下:

  1. <!DOCTYPE html>
    <html lang="zh-CN">
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>向上下左右不间断无缝滚动图片的效果(兼容火狐和IE)</title>
    </head>
    <body>
    <div id="colee" style="overflow:hidden;height:253px;width:410px;">
    <div id="colee1">

    </div>
    <div id="colee2"></div>
    </div>

    var speed=30;

    var colee1=document.getElementById("colee1");
    var colee=document.getElementById("colee");
    colee2.innerHTML=colee1.innerHTML; //克隆colee1为colee2
    function Marquee1(){
    //当滚动至colee1与colee2交界时
    /*if(colee2.offsetTop-colee.scrollTop<=0){
    colee.scrollTop-=colee1.offsetHeight; //colee跳到最顶端
    }else{
    colee.scrollTop++
    }*/
    //无限循环
    if(colee.scrollTop>=colee1.offsetHeight){
    colee.scrollTop=0;
    }
    else
    {
    colee.scrollTop++;
    }
    }
    var MyMar1=setInterval(Marquee1,speed)//设置定时器
    //鼠标移上时清除定时器达到滚动停止的目的
    colee.onmouseover=function() {clearInterval(MyMar1)}
    //鼠标移开时重设定时器
    colee.onmouseout=function(){MyMar1=setInterval(Marquee1,speed)}
    </script>
