js跑马灯效果
开始自己也写了个跑马灯但是那效果不太好过度不够平滑以下是网上找的一个例子效果挺不错的
1.js

<script type="text/javascript" language="Javascript">
var scrlSpeed=1
// decreasing speed for mozilla
scrlSpeed=(document.all)? scrlSpeed : Math.max(1, scrlSpeed-1)
function initScroll(container,object){
    if (document.getElementById(container) != null){
        var contObj=document.getElementById(container);
        var obj=document.getElementById(object);
        contObj.style.visibility = "visible";
        contObj.scrlSpeed = scrlSpeed;
        widthContainer = contObj.offsetWidth;
        obj.style.left=parseInt(widthContainer)+"px";
        widthObject=obj.offsetWidth;
        interval=setInterval("objScroll('"+ container +"','"+ object +"',"+ widthContainer +")",20);
        contObj.onmouseover = function(){
            contObj.scrlSpeed=0;
        }
        contObj.onmouseout = function(){
            contObj.scrlSpeed=scrlSpeed;
        } 
    }
}

function objScroll(container,object,widthContainer){
    var contObj=document.getElementById(container);
    var obj=document.getElementById(object);
    widthObject=obj.offsetWidth;
    if (parseInt(obj.style.left)>(widthObject*(-1))){
        obj.style.left=parseInt(obj.style.left)-contObj.scrlSpeed+"px";
    } else {
        obj.style.left=parseInt(widthContainer)+"px";
    }
}

 

// on page load we initiate scrolling
window.onload=function(){ 
    initScroll("scrlContainer", "scrlContent");
}

</script>

2.css

<style type="text/css">
body{
    margin:0;
    padding:0;
    background:#fff;
    font: 70% Arial, Helvetica, sans-serif;
}
#scrlContainer{
    visibility:hidden;
    background:#f1f1f1;
    position:relative;
    overflow:hidden;
    width:250px;
    height:20px;
    line-height:20px;
    margin:1em;
}

#scrlContent{
    position:absolute;
    left:0;
    top:0;
    white-space:nowrap;
}
</style>

3.html

<html> 
<body>
<div id="scrlContainer">
    <div id="scrlContent">Some very, very useful information will
appear here, yet it will move around your screen so it will be hard to
read it. But the client wants it, so here it is. </div>
</div>              
</body>
</html>
