javascript：
复制代码 代码如下:
    var speed=12; //数字越大速度越慢
    var tab=document.getElementById("index_foot_slide");
    var tab1=document.getElementById("index_foot_slide1");
    var tab2=document.getElementById("index_foot_slide2");
    tab2.innerHTML=tab1.innerHTML;
    function Marquee(){
    if(tab.scrollLeft<=0)
    tab.scrollLeft+=tab2.offsetWidth
    else{
    tab.scrollLeft--
    }
    }
    var MyMar=setInterval(Marquee,speed);
    tab.onmouseover=function() {clearInterval(MyMar)};
    tab.onmouseout=function() {MyMar=setInterval(Marquee,speed)};
