function change(){
if(!document.all)
return
if (event.srcElement.id=="foldheader") {
var srcIndex = event.srcElement.sourceIndex
var nested = document.all[srcIndex+1]
if (nested.style.display=="none") {
nested.style.display=''
event.srcElement.style.listStyleImage="url(img/open.gif)"
}
else {
nested.style.display="none"
event.srcElement.style.listStyleImage="url(img/fold.gif)"
}
}
}

document.onclick=change

//-->
</script>
<% sqlstr="SELECT distinct classname FROM leibie "
set rs=conn.execute(sqlstr) %>

<% do while not rs.eof %>
<li id=foldheader>
<%=rs("classname")%><%cl=rs("classname")%> //怎樣將CL的數值傳遞給下面的classs(上面的change()要怎么改?)
<ul id=foldinglist style="DISPLAY: none">
<% sqlstr="SELECT classs FROM leibie where classs='"&cl&"' "//我要把CL傳到這里來!(當我點激樹型菜單時只彈出几行空白,根本就沒彈出classs的值.我把where條件去掉,所有的classs值全部彈出.這不是我要的效果.)
set rs4=conn.execute(sqlstr) %>
<% do while not rs4.eof %>

<li><a href="<%=rs4("classs")%>.html"><%=rs4("classs")%></a>

<% rs4.movenext
loop

<%rs.movenext
loop
