Hi,

i found this script on the DD site:


<script type="text/javascript">

/***********************************************

var enablepersist="on" //Enable saving state of content structure using session cookies? (on/off)
var collapseprevious="no" //Collapse previously open content when opening present? (yes/no)

if (document.getElementById){
document.write('<style type="text/css">')
document.write('.switchcontent{display:none;}')
document.write('</style>')
}

function getElementbyClass(classname){
ccollect=new Array()
var inc=0
var alltags=document.all? document.all : document.getElementsByTagName("*")
for (i=0; i<alltags.length; i++){
if (alltags[i].className==classname)
ccollect[inc++]=alltags[i]
}
}

function contractcontent(omit){
var inc=0
while (ccollect[inc]){
if (ccollect[inc].id!=omit)
ccollect[inc].style.display="none"
inc++
}
}

function expandcontent(cid){
if (typeof ccollect!="undefined"){
if (collapseprevious=="yes")
contractcontent(cid)
document.getElementById(cid).style.display=(document.getElementById(cid).style.display!="block")? "block" : "none"
}
}

function revivecontent(){
contractcontent("omitnothing")
selectedItem=getselectedItem()
selectedComponents=selectedItem.split("|")
for (i=0; i<selectedComponents.length-1; i++)
document.getElementById(selectedComponents[i]).style.display="block"
}

function get_cookie(Name) {
var search = Name + "="
var returnvalue = "";
if (document.cookie.length > 0) {
offset = document.cookie.indexOf(search)
if (offset != -1) {
offset += search.length
end = document.cookie.indexOf(";", offset);
if (end == -1) end = document.cookie.length;
returnvalue=unescape(document.cookie.substring(offset, end))
}
}
return returnvalue;
}

function getselectedItem(){
if (get_cookie(window.location.pathname) != ""){
selectedItem=get_cookie(window.location.pathname)
return selectedItem
}
else
return ""
}

function saveswitchstate(){
var inc=0, selectedItem=""
while (ccollect[inc]){
if (ccollect[inc].style.display=="block")
selectedItem+=ccollect[inc].id+"|"
inc++
}

document.cookie=window.location.pathname+"="+selectedItem
}

function do_onload(){
uniqueidn=window.location.pathname+"firsttimeload"
getElementbyClass("switchcontent")
if (enablepersist=="on" && typeof ccollect!="undefined"){
document.cookie=(get_cookie(uniqueidn)=="")? uniqueidn+"=1" : uniqueidn+"=0"
firsttimeload=(get_cookie(uniqueidn)==1)? 1 : 0 //check if this is 1st page load
if (!firsttimeload)
revivecontent()
}
}


if (window.addEventListener)
window.addEventListener("load", do_onload, false)
else if (window.attachEvent)
window.attachEvent("onload", do_onload)
else if (document.getElementById)
window.onload=do_onload

if (enablepersist=="on" && document.getElementById)
window.onunload=saveswitchstate

</script>

Now I want to use 2 of this on one page (2 different menu's) and the settings enablepersist and collapseprevious should difference so i edited like;


<script type="text/javascript">

var opslagen="on" //Enable saving state of content structure using session koekjes? (on/off)
var vorigedicht="no" //Collapse previously open content when opening present? (yes/no)

if (document.getElementById){
document.write('<style type="text/css">')
document.write('.SwitchMenu{display:none;}')
document.write('</style>')
}

function getElementbyClass(classname){
ccollect=new Array()
var inc=0
var alltags=document.all? document.all : document.getElementsByTagName("*")
for (i=0; i<alltags.length; i++){
if (alltags[i].className==classname)
ccollect[inc++]=alltags[i]
}
}

function kontraktMenu(omit){
var inc=0
while (ccollect[inc]){
if (ccollect[inc].id!=omit)
ccollect[inc].style.display="none"
inc++
}
}

function breiduitMenu(cid){
if (typeof ccollect!="undefined"){
if (vorigedicht=="yes")
kontraktMenu(cid)
document.getElementById(cid).style.display=(document.getElementById(cid).style.display!="block")? "block" : "none"
}
}

function herleefMenu(){
kontraktMenu("omitnothing")
selectedItem=getselectedItem()
selectedComponents=selectedItem.split("|")
for (i=0; i<selectedComponents.length-1; i++)
document.getElementById(selectedComponents[i]).style.display="block"
}

function get_koekje(Name) {
var search = Name + "="
var returnvalue = "";
if (document.koekje.length > 0) {
offset = document.koekje.indexOf(search)
if (offset != -1) {
offset += search.length
end = document.koekje.indexOf(";", offset);
if (end == -1) end = document.koekje.length;
returnvalue=unescape(document.koekje.substring(offset, end))
}
}
return returnvalue;
}

function getselectedItem(){
if (get_koekje(window.location.pathname) != ""){
selectedItem=get_koekje(window.location.pathname)
return selectedItem
}
else
return ""
}

function opslaanSwitchMenu(){
var inc=0, selectedItem=""
while (ccollect[inc]){
if (ccollect[inc].style.display=="block")
selectedItem+=ccollect[inc].id+"|"
inc++
}

document.koekje=window.location.pathname+"="+selectedItem
}

function do_onload(){
uniqueidn=window.location.pathname+"firsttimeload"
getElementbyClass("SwitchMenu")
if (opslagen=="on" && typeof ccollect!="undefined"){
document.koekje=(get_koekje(uniqueidn)=="")? uniqueidn+"=1" : uniqueidn+"=0"
firsttimeload=(get_koekje(uniqueidn)==1)? 1 : 0 //check if this is 1st page load
if (!firsttimeload)
herleefMenu()
}
}


if (window.addEventListener)
window.addEventListener("load", do_onload, false)
else if (window.attachEvent)
window.attachEvent("onload", do_onload)
else if (document.getElementById)
window.onload=do_onload

if (opslagen=="on" && document.getElementById)
window.onunload=opslaanSwitchMenu

</script>
But saving the state doesn't work, probably because of the cookie name?
Could anyone tell me how to solve this?

You can't use 2 javascripts on one page without major modifications.
