<script>
toleft("demo","demo1","demo2",30,"onedemo");
//toright("demo0","demo11","demo22",20,"ti2");
</script>

js核心代码


代码如下:

//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)
{
demo=$(demo);
demo1=$(demo1);
demo2=$(demo2)
demo2.innerHTML=demo1.innerHTML
function Marquee()
{
if(demo.scrollLeft<=0)
{
demo.scrollLeft=demo2.offsetWidth
}
else
{
demo.scrollLeft--
}
}
flag=setInterval(Marquee,speed)
demo.onmouseover=function()
{
clearInterval(flag);
}
demo.onmouseout=function()
{
flag=setInterval(Marquee,speed);
}
}

如需要更多的功能可以参考下面的内容：
