I need some JavaScript help

I have this function that I need to take out of my HTML page.

I'd like to save it as a separate file (js) and call it from multiple pages. Unfortunately, I can't get it to work. 🙂

<script language="JavaScript1.2">
<!--
/**
* Get cookie routine by Shelley Powers
* (shelley.powers@ne-dev.com)
*/
function get_cookie(Name) {
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;
}

if (get_cookie(window.location.pathname) != ''){
var openresults=get_cookie(window.location.pathname).split(" ")
for (i=0 ; i < openresults.length ; i++){
foldinglist[openresults].style.display=''
document.all[foldinglist[openresults].sourceIndex -
1].style.listStyleImage="url(open.gif)"
}
}

if (document.all){
var nodelength=foldinglist.length-1
var nodes=new Array(nodelength)
var openones=''
}

function check(){
for (i=0 ; i <= nodelength ; i++){
if (foldinglist.style.display=='')
openones=openones + " " + i
}
document.cookie=window.location.pathname+"="+openones
}

if (document.all)
document.body.onunload=check
//-->
</script>

Thanks for you help.
 
This looks like client-side javascript. You're going to have to include it in the page somehow (SSI, php include, etc.)

 
For the record, I don't know too much about this stuff, but I disagree.

It came out of my HTML editor, and it works just fine that way. Maybe I should include the entire thing.

<html>
<head>
<title>Some Title</title>
<style>
<!--
#foldheader{cursor:hand ; font-weight:bold ;
list-style-image:url(fold.gif)}
#foldinglist{list-style-image:url(list.gif)}
//-->
</style>

I have the links script set as a separate document that is called from every webpage, but none of the pages remember what the tree should look like when you refresh the page, or click an internal link. If someone has the tree open and clicks on a link, I don't want them to click through the tree to get back to the level they were at. Does that make sense?

To do this, copy all the JavaScript code (do not include the <script> tags) and paste it into a file called name.js. Then add this line in your HTML:

<script language="JavaScript" type="text/javascript" src="name.js"></script>
