网页设计中让图片轮播，需要用到的JS和比较好的div+css布局意识，主要还是需要了解left，top在css中的意思，这里我提交一段我以前写的代码；
html中的代码：
<div id="box">
<div id="woZaiHouDun" class='hide' >
<a id="btnLeft" href='javascript:void(0);'> </a>
<a id="btnRight" href='javascript:void(0);'> </a>
<ul>
<li><img width="400" height="260" src="./images/scholl/1.jpg"/></li>
<li><img width="400" height="260" src="./images/scholl/2.jpg"/></li>
<li><img width="400" height="260" src="./images/scholl/3.jpg"/></li>
<li><img width="400" height="260" src="./images/scholl/1.jpg"/></li>
<li><img width="400" height="260" src="./images/scholl/2.jpg"/></li>
<li><img width="400" height="260" src="./images/scholl/3.jpg"/></li>
<li><img width="400" height="260" src="./images/scholl/1.jpg"/></li>
<li><img width="400" height="260" src="./images/scholl/2.jpg"/></li>
<li><img width="400" height="260" src="./images/scholl/3.jpg"/></li>
</ul>
</div>
js中的代码：
ar t=null;
function woZaiHouDun(){
var oUl = document.getElementById('woZaiHouDun').getElementsByTagName('ul')[0];
var aLi = oUl.getElementsByTagName('li');
oUl.innerHTML += oUl.innerHTML;
oUl.style.width = aLi[0].offsetWidth*aLi.length + 'px';
var oBtnLeft = document.getElementById('btnLeft');
var oBtnRight = document.getElementById('btnRight');
var iTarget = 0;
var ispeed = -3;
oBtnLeft.onclick = function(){
ispeed = 3;
}
oBtnRight.onclick = function(){
ispeed = -3;
}
t=setInterval(function(){
iTarget = oUl.offsetLeft -ispeed;
if( iTarget < - oUl.offsetWidth/2){
oUl.style.left =0 +'px';
iTarget = oUl.offsetLeft -ispeed;
}
if( iTarget > 0){
oUl.style.left =- oUl.offsetWidth/2 +'px';
iTarget = oUl.offsetLeft -ispeed;
}
oUl.style.left =iTarget +'px';
},30)
}
这样是能实现轮播的。

网页轮播？是图片还是轮播还是网页啊，网页还可以轮播？
