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)};
