div+css学习笔记22(用div实现向左无缝滚动图片效果)JavaScript实现走马灯效果[无缝连接、循环滚动] 无缝跑马灯效果

以下代码在IE6、Firefox+Win2k环境下测试通过

网页走马灯连续循环滚动

废话少说,代码贴出来:

<div id="imgmarquee" style="OVERFLOW: hidden; WIDTH: 580px; align: left; background-color:#0099CC;">

<div style="width:1200px">

<!--id="marquePic1"里面的宽度一定要大于id="imgmarquee"的宽度才能看到效果 width:600px;>WIDTH: 580px;

大的div宽度要为span的两倍才可以,不然会换行width:1200px zdz的作品,流风的作品 -->

   <span id="marquePic1" style="width:600px; background-color:#990033;">

   <img src="../images/dialog/4.gif" />

   <img src="../images/dialog/4.gif" />

   <img src="../images/dialog/4.gif" />

   <img src="../images/dialog/4.gif" />

   <img src="../images/dialog/4.gif" />

   <img src="../images/dialog/4.gif" />

   </span>

   <span id="marquePic2" style="width:600px;background-color:#990033;"></span>

</div>

</div>

<script type="text/javascript">

var imgmarquee = document.getElementById('imgmarquee');

var marquePic2 = document.getElementById('marquePic2');

var marquePic1 = document.getElementById('marquePic1');

var speed=10;//控制移动的速度,数越大越慢

marquePic2.innerHTML=marquePic1.innerHTML;//把marquePic1的内容复制到marquePic2里面

function Marquee(){

if(imgmarquee.scrollLeft>=marquePic1.scrollWidth){

imgmarquee.scrollLeft=0;

}else{

//demo.scrollLeft++;

imgmarquee.scrollLeft++;

}

}

var marqueetemp=setInterval(Marquee,speed);

imgmarquee.onmouseover=function() {clearInterval(marqueetemp)} //鼠标移到上面停止并清除计数

imgmarquee.onmouseout=function() {marqueetemp=setInterval(Marquee,speed)} //鼠标离开重新计数

</script>

参考资料(向右,向上,向下代码同理,只是控制的js不同而已,把下面的id改成对应的就ok了)

其中<div id=gleft>这里的gleft的样式你自己定义下就OK了
