※ 引述《agird (二青)》之銘言：
從教學網站抓的script XD
http://www.dynamicdrive.com/dynamicindex1/navigate1.htm
Step1. 把那三張圖抓回來 (可有可無)
Step2. 在 <HEAD> ... </HEAD>加入
<style>
<!--
#foldheader{cursor:pointer;cursor:hand ; font-weight:bold ;
list-style-image:url(fold.gif)}
#foldinglist{list-style-image:url(list.gif)}
//-->
</style>
<script language="JavaScript1.2">
<!--
//Smart Folding Menu tree- By Dynamic Drive (rewritten 03/03/02)

//This credit MUST stay intact for use
var head="display:''"
img1=new Image()
img1.src="fold.gif"
img2=new Image()
img2.src="open.gif"
var ns6=document.getElementById&&!document.all
var ie4=document.all&&navigator.userAgent.indexOf("Opera")==-1
function checkcontained(e){
var iscontained=0
cur=ns6? e.target : event.srcElement
i=0
if (cur.id=="foldheader")
iscontained=1
else
while (ns6&&cur.parentNode||(ie4&&cur.parentElement)){
if (cur.id=="foldheader"||cur.id=="foldinglist"){
iscontained=(cur.id=="foldheader")? 1 : 0
break
}
cur=ns6? cur.parentNode : cur.parentElement
}
if (iscontained){
var foldercontent=ns6? cur.nextSibling.nextSibling : cur.all.tags("UL")[0]
if (foldercontent.style.display=="none"){
foldercontent.style.display=""
cur.style.listStyleImage="url(open.gif)"
}
else{
foldercontent.style.display="none"
cur.style.listStyleImage="url(fold.gif)"
}
}
}
if (ie4||ns6)
document.onclick=checkcontained
//-->
</script>
Step3.把以下code 放入 <body> .. </body> 之間
然後記得把選單的字和超連結修改
<font face="Verdana">
<ul>
<li id="foldheader">News</li>
<ul id="foldinglist" style="display:none" style=&{head};>
<li><a href="
http://www.cnn.com">CNN</a></li>
<li><a href="
http://www.abcnews.com">ABC News</a></li>
<li><a href="

</ul>
<li id="foldheader">Webmaster</li>
<ul id="foldinglist" style="display:none" style=&{head};>

</ul>
<li><a href="

</ul>
</ul>
</font>

Step4. 加入到整個頁面的最下面(?)
<script language="JavaScript1.2">
<!--
function get_cookie(Name) {
//Get cookie routine by Shelley Powers
var search = Name + "="
var returnvalue = "";
if (document.cookie.length > 0) {
offset = document.cookie.indexOf(search)
// if cookie exists
if (offset != -1) {
offset += search.length
// set index of beginning of value
end = document.cookie.indexOf(";", offset);
// set index of end of cookie value
if (end == -1) end = document.cookie.length;
returnvalue=unescape(document.cookie.substring(offset, end))
}
}
return returnvalue;
}
var foldercontentarray=new Array()
var c=0
if (ns6){
for (i=0;i<document.getElementsByTagName("UL").length;i++){
if (document.getElementsByTagName("UL")[i].id=="foldinglist"){
foldercontentarray[c]=document.getElementsByTagName("UL")[i]
c++
}
}
}
if (get_cookie(window.location.pathname) != ''){
var openresults=get_cookie(window.location.pathname).split(" ")
for (i=0 ; i < openresults.length ; i++){
if (ns6){
foldercontentarray[openresults[i]].style.display=''
foldercontentarray[openresults[i]].previousSibling.previousSibling.style.listStyleImage="url(open.gif)"
}
else{
foldinglist[openresults[i]].style.display=''
document.all[foldinglist[openresults[i]].sourceIndex
-1].style.listStyleImage="url(open.gif)"
}
}
}
if (ns6||ie4){
var nodelength=ns6? c-1 : foldinglist.length-1
var nodes=new Array(nodelength)
var openones=''
}
function checkit(){
for (i=0 ; i <= nodelength ; i++){
if
((ns6&&foldercontentarray[i].style.display=='')||(ie4&&foldinglist[i].style.display==''))
openones=openones + " " + i
}
document.cookie=window.location.pathname+"="+openones
}
if (ns6||ie4)
window.onunload=checkit

另外推這個好站:
http://www.dynamicdrive.com 很多好的功能可以抓
而且大部分都是 IE 與 NS 雙支援
