js实现的类marquee水平循环滚动_javascript技巧

来源：爱娱乐

代码如下:

var speed=20;/*速度数值越大速度越慢*/
document.getElementById('www_qpsh_com2').innerHTML=document.getElementById('www_qpsh_com1').innerHTML;

/*两个层来回交替出现*/
function Marquee(){
if(document.getElementById('www_qpsh_com2').offsetWidth-document.getElementById('www_qpsh_com').scrollLeft<=0)
document.getElementById('www_qpsh_com').scrollLeft-=document.getElementById('www_qpsh_com1').offsetWidth;
else{
document.getElementById('www_qpsh_com').scrollLeft++;
}
document.getElementById('my_marquee_info').innerHTML='';
document.getElementById('my_marquee_info').innerHTML+='div.scrollTop:'+document.getElementById('www_qpsh_com').scrollLeft;
}
var MyMar=setInterval(Marquee,speed);
www_qpsh_com.onmouseover=function() {clearInterval(MyMar);}
www_qpsh_com.onmouseout=function() {MyMar=setInterval(Marquee,speed);}

演示代码:
