Help Creating JS Relative Path Function

[b1azesk]

I'm trying to write a Javascript to set a relative path for my files, s
I don't have to type in an absolute path. I know that I need to someho
define the root directory, likely using /, then I need to have th
function check to see where the file sits, then add the appropriat
../ infront of it.

Unfortunatly I'm totally stumped as to what I need to do. A
ex-co-worker of mine used to have a function similar to this, howeve
we've lost touch.

Anyone have an idea how this might work? It makes it so much easier t
place items into webpages without having to hardcode the entire pat
for everything.

Regards,

John William

function getPath( ){
var path = document.locati on;
var str = new String(path);
var len = str.length;
var start = str.lastIndexOf ("/");
var document_path = str.substring(s tart +1,len);
alert(document_ path);
}

var loc=location.to String()

Did you know that, because it starts with a slash, <a href="/some/dir/">
always points to same location, no matter how deep in your site you put this
link? No javascript needed at all!

Apart from that:

document.locati on.pathname.spl it('/').length-2

is a number representing the number of subdirectories. So

var path='';
for( var i=0; i<document.loca tion.pathname.s plit('/').length-2; i++)
path+='../';

will give you a string which can be used to back up to the root. Not sure if
this is what you were looking for.
