[js脚本实现]图片向上滚动并且有停顿的特效
<!-- 把下列代码放到<body>中-->
<table width="100%" border="0" cellpadding="0" cellspacing="0">
<tr>
<td>
<table width="500" border="0" cellspacing="0" align="center">
<tr><td>
<div ></div>
</td></tr>

function init_srolltext1(){
article2.innerHTML="";
article2.innerHTML+=article1.innerHTML;
article1.innerHTML=article2.innerHTML+article2.innerHTML;
setInterval("scrollUp1()",1); //图片滚动速度
}
function scrollUp1(){
if(stopscrolla==true) return;
currentTopa+=1;
if(currentTopa==81)//设置为图片高度稍大一些，防止出现多次滚动后留边

}
}
