我发现这个小代码用于在占位符中旋转图像，此时我只能放置一个，有人可以帮我编码，将不同的文件夹放在相同或不同的页面中旋转..
<script language="JavaScript1.2">
var howOften = 5; //number often in seconds to rotate
var current = 0; //start the counter at 0
var ns6 = document.getElementById&&!document.all; //detect netscape 6
// place your images, text, etc in the array elements here
var items = new Array();
items[0]="<a href='images/rotate/1.jpg'><img alt='image0 (9K)' src='images/rotate/1.jpg' height='300' width='300' border='0' /></a>"; //a linked image
items[1]="<a href='images/rotate/2.jpg'><img alt='image1 (9K)' src='images/rotate/2.jpg' height='300' width='300' border='0' /></a>"; //a linked image
items[2]="<a href='images/rotate/3.jpg'><img alt='image2 (9K)' src='images/rotate/3.jpg' height='300' width='300' border='0' /></a>"; //a linked image
items[3]="<a href='images/rotate/4.jpg'><img alt='image3 (9K)' src='images/rotate/4.jpg' height='300' width='300' border='0' /></a>"; //a linked image
items[4]="<a href='images/rotate/1.jpg'><img alt='image4 (9K)' src='images/rotate/1.jpg' height='300' width='300' border='0' /></a>"; //a linked image
items[5]="<a href='images/rotate/2.jpg'><img alt='image5 (18K)' src='images/rotate/2.jpg' height='300' width='300' border='0' /></a>"; //a linked image
function rotater() {
document.getElementById("placeholder").innerHTML = items[current];
current = (current==items.length-1) ? 0 : current + 1;
setTimeout("rotater()",howOften*1000);
}
function rotater() {
if(document.layers) {
document.placeholderlayer.document.write(items[current]);
document.placeholderlayer.document.close();
}
if(ns6)document.getElementById("placeholderdiv").innerHTML=items[current]
if(document.all)
placeholderdiv.innerHTML=items[current];
current = (current==items.length-1) ? 0 : current + 1; //increment or reset
setTimeout("rotater()",howOften*1000);
}
window.onload=rotater;
//-->
