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>");
    }

        divColl = document.all.tags("DIV");
        for (i=0; i<divColl.length; i++) {
            whichEl = divColl(i);
            if (whichEl.className == "child") whichEl.style.display = "none";
        }

}

        whichEl = eval(el + "Child");

onload = initIt;
</script>
