前几天工作时遇到的一问题，不会写JS，请大猪来帮我写的，谢谢大猪了。
图片从右至左滚动JS代码：
1、直线滚动

<div id="ad" style="position:absolute;width:150px;left:800;top:300"><a href="  " target="_blank" style="width:100%;height:100%;"><img src="http://www.google.com/intl/zh-CN/logos/holiday06_2.gif" border="0" /></a></div>    <script defer="defer">    var x =800    var y=300    var yp=35    var yn=0    var yin=true    var xin = true    var step = 1     var delay = 30    var obj=document.getElementById("ad")     function floatAD() {       var L=-obj.offsetWidth;       var R= document.body.clientWidth-obj.offsetWidth              obj.style.left = x + document.body.scrollLeft           x = x + step*(xin?1:-1)         if (x < L) { xin = true; x = R}        if (x > R){ xin = false; x = R}        var T=0       var B = document.body.clientHeight-obj.offsetHeight       obj.style.top =y+ yn+ document.body.scrollTop               if (yin){ yn=yn+1/Math.sin(1);}         else{yn=yn-1/Math.sin(1);}              if (yn >yp) { yin = false }        if (yn <-yp) { yin = true }     }    var itl= setInterval("floatAD()", delay)    obj.onmouseover=function(){clearInterval(itl)}    obj.onmouseout=function(){itl=setInterval("floatAD()", delay)}    </script>

2、波浪滚动

<div id="ad" style="position:absolute;width:150px;left:800;top:300">  <div style="position:relative;red;right:0px;top:0px;text-align:right;cursor:pointer" onClick=CloseAD()>[X]</div>  <a href="" target="_blank" style="position:relative;left:0px;top:0px"><img width=150px src="http://www.google.com/intl/zh-CN/logos/holiday06_2.gif" border="0" /></a>  </div>    <script defer="defer">    var x = 800    var y=300    var yp=35    var yn=0    var yin=true    var xin = true    var step = 1     var delay =20      var obj=document.getElementById("ad")      var itl    function CloseAD(){          clearInterval(itl);     obj.style.display="none";    }    function floatAD() {       var L=-obj.offsetWidth;       var R= document.body.clientWidth-obj.offsetWidth              obj.style.left = x + document.body.scrollLeft           x = x + step*(xin?1:-1)         if (x < L) { xin = true; x = R}        if (x > R){ xin = false; x = R}        var T=0              obj.style.top =y+ yn+ document.body.scrollTop       if (x%2==0){        if (yin){ yn=yn+1/Math.sin(1);}         else{yn=yn-1/Math.sin(1);}              if (yn >yp) { yin = false }        if (yn <-yp) { yin = true }     }    }    itl= setInterval("floatAD()", delay)    obj.onmouseover=function(){clearInterval(itl)}    obj.onmouseout=function(){itl=setInterval("floatAD()", delay)}    </script>
