关于新闻滚动
为什么我按照这样写，他无法实现滚动了？求解！ <script type ="text/javascript">
var speed3 = 30
m3.innerHTML = mtext3.innerHTML
function Marquee3() {
if (m3.offsetTop - maq3.scrollTop <= 0)
maq3.scrollTop -= mtext3.offsetHeight
else {
maq3.scrollTop++
}
}
var MyMar3 = setInterval(Marquee3, speed3)
maq3.onmouseover = function () { clearInterval(MyMar3) }
maq3.onmouseout = function () { MyMar3 = setInterval(Marquee3, speed3) }
</script>
</head>
