javascript document root relative

I have a javascript menu that I would like to use only once across the whole site.  My site looks like this:


So the links in my script are like:

I would like to have the javascript file reside on the highest level but when I do the links wont work on the lower levels.  This is all about the document's relative path.  Is there anyway to solve this so that the menu link (from the script file) in folder2/foldera/file3.html would point back to ../../folder1/file.html?

make sense?

Your script can read the actual window location and document location.
According to actual location your menu can adapt, for example by comparing to a common base for script and for the page using the script.

Put your script relative to server root.
code your links from the root:

Also look whether <base> tag is of help to you:

there's a problem with IE (well it's a matter of taste probably) that IE interpretes links to a certain frame relative to the current location of the document in the frame. Even if the links are clicked from another frame. Netscape/Mozilla takes link relative to the location of the document where the click is being done. It's been this way forever, and i don't know why they never get on speaking terms about this.

- make sure that every link is defined from the root (start with "/")
- use the <base> tag (as NetGroove says)

maybe some other depending on the situation

Sorry none of those really help out.  My javascript file generates the menu.  I can link to the javascript files just fine.  BUT it is the menu that is generated by the javascript that needs to change with the document location.  Is there anyway to do this within javascript?  Basically, find the current document's location then traverse back to the server root and generate a dynamic menu that will automatically make all the links valid.
Sorry, I just noticed that I repeated your last sentence.
Now when you know that actual window URL is readable by your script, then what is your question???

How do you make the script use the current location to dynamically build the menu?  based upon document.location I was thinking you could parse the string and find the "/" and build a dynamic ../  make sense?
Of course make sense. But what is your question?
You can make it any way around.
Decide what you want and I can show you how to do.

If your site is partially online or if your sources are les then let say three hundred lines, then post it here.

I think I figured it out.  I found enough documentation out there to make it a dynamic menu.  thanks
