JavaScript实现图片的不间断连续滚动

80酷酷网    80kuku.com

  javascript

制作的代码不给大家加注释了!代码中的图片大家都可以自己加上自己的超级连接,修改的方法为:<a href="连接的地址" target=_blank><img src="http://www.pushad.com/img/link.gif" width=图片宽度 height=图片高度 border="0"></a>

  先制作向上滚动的效果: 

<!-- 指向链接图片url -->
<base href="http://www.xrss.cn">
<div id=demo id=demo1>
<!-- 定义图片 -->
<img src="http://www.pushad.com/img/link.gif">
<img src="http://www.pushad.com/img/link1.gif">
<img src="http://www.pushad.com/img/link2.gif">
<img src="http://www.pushad.com/img/link3.gif">
<img src="http://www.pushad.com/img/link4.gif">
</div>
<div id=demo2></div>
</div>


<script>
var speed=30
demo2.innerHTML=demo1.innerHTML
function Marquee(){
if(demo2.offsetTop-demo.scrollTop<=0)
demo.scrollTop-=demo1.offsetHeight
else{
demo.scrollTop++
}
}
var MyMar=setInterval(Marquee,speed)
demo.onmouseover=function() {clearInterval(MyMar)}
demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
</script>

  制作向下滚动的效果: 

  将上面“制作向上滚动的效果”中的红色字体Js部分替换成:

<script>
var speed=30
demo2.innerHTML=demo1.innerHTML
demo.scrollTop=demo.scrollHeight
function Marquee(){
if(demo1.offsetTop-demo.scrollTop>=0)
demo.scrollTop+=demo2.offsetHeight
else{
demo.scrollTop--
}
}
var MyMar=setInterval(Marquee,speed)
demo.onmouseover=function() {clearInterval(MyMar)}
demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
</script>

  制作向左滚动的效果: 

<base href="http://www.xrss.cn">
<div id=demo align=left cellpadding=0 cellspace=0 border=0>
<tr>
<td id=demo1 valign=top><img src="http://www.pushad.com/img/link.gif"><img src="http://www.pushad.com/img/link1.gif"><img src="http://www.pushad.com/img/link2.gif"><img src="http://www.pushad.com/img/link3.gif">
</td>
<td id=demo2 valign=top></td>
</tr>
</table>
</div>

<script>
var speed=30
demo2.innerHTML=demo1.innerHTML
function Marquee(){
if(demo2.offsetWidth-demo.scrollLeft<=0)
demo.scrollLeft-=demo1.offsetWidth
else{
demo.scrollLeft++
}
}
var MyMar=setInterval(Marquee,speed)
demo.onmouseover=function() {clearInterval(MyMar)}
demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
</script>
 
  制作向右滚动的效果: 
  将上面“制作向左滚动的效果”中的红色字体Js部分替换成:
<script>
var speed=30
demo2.innerHTML=demo1.innerHTML
demo.scrollLeft=demo.scrollWidth
function Marquee(){
if(demo.scrollLeft<=0)
demo.scrollLeft+=demo2.offsetWidth
else{
demo.scrollLeft--
}
}
var MyMar=setInterval(Marquee,speed)
demo.onmouseover=function() {clearInterval(MyMar)}
demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}
</script>
