如何修改此函数,以改变滚动的速度,和改变停顿的时间

改好了。

<!--
function _InitScroll(_S1,_S2,_W,_H,_T,_V){
return "var marqueesHeight"+_S1+"="+_H+";var stopscroll"+_S1+"=false;var scrollElem"+_S1+"=document.getElementById('"+_S1+"');with(scrollElem"+_S1+"){style.width="+_W+";style.height=marqueesHeight"+_S1+";style.overflow='hidden';noWrap=true;}scrollElem"+_S1+".onmouseover=new Function('stopscroll"+_S1+"=true');scrollElem"+_S1+".onmouseout=new Function('stopscroll"+_S1+"=false');var preTop"+_S1+"=0; var currentTop"+_S1+"=0; var stoptime"+_S1+"=0;var leftElem"+_S2+"=document.getElementById('"+_S2+"');scrollElem"+_S1+".appendChild(leftElem"+_S2+".cloneNode(true));setTimeout('init_srolltext"+_S1+"()',"+_T+");function init_srolltext"+_S1+"(){scrollElem"+_S1+".scrollTop=0;setInterval('scrollUp"+_S1+"()',"+_V+");}function scrollUp"+_S1+"(){if(stopscroll"+_S1+"){return;}currentTop"+_S1+"+=1;if(currentTop"+_S1+"==(marqueesHeight"+_S1+"+1)) {stoptime"+_S1+"+=1;currentTop"+_S1+"-=1;if(stoptime"+_S1+"=="+_T/50+") {currentTop"+_S1+"=0;stoptime"+_S1+"=0;}}else{preTop"+_S1+"=scrollElem"+_S1+".scrollTop;scrollElem"+_S1+".scrollTop +=1;if(preTop"+_S1+"==scrollElem"+_S1+".scrollTop){scrollElem"+_S1+".scrollTop=0;scrollElem"+_S1+".scrollTop +=1;}}}";

你的代码太乱，偶看不清，我刚帮别人解决了一个类似问题，你可以贴着看看。
很好用的，设两个变量,得用取模来获取时间差。
<script language=javascript defer>
marqueeDiv1.childOffsetWidth=marqueeDiv1.children[0].offsetWidth;
marqueeDiv1.insertAdjacentHTML("beforeEnd",marqueeDiv1.innerHTML+marqueeDiv1.innerHTML);
var i = 0;
var j = 1;
window.setInterval(pause_it,60);
function pause_it()
{
///时间间隔 ,改变值，即可伸缩时间
if (i%10 == 0)
{
if(j++ %20) return;
}
marqueeDiv1.scrollLeft=(marqueeDiv1.scrollLeft+marqueeDiv1.tempSpeed*1)%marqueeDiv1.childOffsetWidth;


i++;
}

</script>
<div id=marqueeDiv1 nowrap style="width:300;overflow:hidden;background-color:#cccccc;" defaultSpeed=2 tempSpeed=2 onmouseOver="this.tempSpeed=0;" onmouseOut="this.tempSpeed=this.defaultSpeed;">
<span style="width:180;">
<table border="0" cellspacing="7" cellpadding="0">
<tr>
<td width="50"><img src="img/1.jpg" width="50" height="100" alt="图片一"></td>
<td width="50"><img src="img/2.jpg" width="50" height="100" alt="图片二"></td>
<td width="50"><img src="img/3.jpg" width="50" height="100" alt="图片三"></td>
<td width="50"><img src="img/4.jpg" width="50" height="100" alt="图片四"></td>
<td width="50"><img src="img/5.jpg" width="50" height="100" alt="图片五"></td>
</tr>
</table>
</span>
</div>
