js核心代码 
//调用向左滚动 
//toleft("demo","demo1","demo2",30,"ti1") 
//调用向右滚动 
//toright("demo0","demo11","demo22",20,"ti2") 

function $(id) 
{ 
return document.getElementById(id) 
} 

//向左滚动函数，demo包含demo1与demo2,speed是滚动速度，flag一个网页内有多个时设置为不同的任意字符。 
function toleft(demo,demo1,demo2,speed,flag) 
{ 
demo=$(demo); 
demo1=$(demo1); 
demo2=$(demo2) 
demo2.innerHTML=demo1.innerHTML 
function Marquee() 
{ 
if(demo2.offsetWidth-demo.scrollLeft<=0) 
{ 
demo.scrollLeft-=demo1.offsetWidth 
} 
else 
{ 
demo.scrollLeft++ 
} 
} 
flag=setInterval(Marquee,speed) 
demo.onmouseover=function() 
{ 
clearInterval(flag); 
} 
demo.onmouseout=function() 
{ 
flag=setInterval(Marquee,speed); 
} 
} 
//向右滚动函数，demo包含demo1与demo2,speed是滚动速度，flag一个网页内有多个时设置为不同的任意字符。 
function toright(demo,demo1,demo2,speed,flag)
