一个FTP树状目录（PHP）

结合js做的,具体的话相应要做修改,比如目录制
[HTML]
<script language="Javascript">
with (document) {
write("<STYLE TYPE='text/css'>");
write(".child ")
write("</STYLE>");
}
function initIt(){
divColl = document.all.tags("DIV");
for (i=0; i<divColl.length; i++) {
whichEl = divColl(i);
if (whichEl.className == "child") whichEl.style.display = "none";
}}
function expandIt(el) {        whichEl = eval(el + "Child");
if (whichEl.style.display == "none") {
whichEl.style.display = "block";
}
else {
whichEl.style.display = "none";
}
}
onload = initIt;
</script>
<LINK href=../main.css rel=stylesheet type=text/css>

以下为类文件
以下内容为程序代码:

}
function pwd()//取得路径
