How to give an ID value from tha directory name?

Hi everyone,
I'm super-newbie here... so thanx in advance for any help

I shoud give a "value" to an DIV's ID that change following the name of the
directory where the file is.

For example the file is here:
www.website.com/web/01/file.html

Is it possible with javascript to give the value "01" to the DIV's ID?
<div id="namedirectory"> something inside </div>
so it could be readed as:
<div id="01"> something inside </div>

I found in internet this one:

<script language="JavaScript">
fullpath=location.pathname;
document.write(fullpath);
document.write('<br />');
result=fullpath.split("\\");
document.write(result[5]);
</script>

it's something that could work?
I don't know how to recall the value in the ID...

Thanx a lot
Cheers,
Luca

Hi Luca.

If I understand what you want to do correctly, you should be able to do
this.

var div = document.getElementById('01');

div will now become a pointer to the dic element with th id of 01.

I would just like to point out, that as a rule of thumb, ALL ids should
start with a letter, and not a number.

'd1' would be an acceptable id name, whereas '1d' would not be as it
starts with a number. Also, ids need to be unique.

If you wanted to list all the div elements in the document, you can do
this with a while loop like so:

var divs = document.getElementsByTagName('div');
for (var i = 0; i < divs.length; i++)
{
// Do stuff with div her, perhaps alert it's name if it has one,
like so...
alert(divs[i].name);
}

If you want to dynamically change the id of the dive (not that you
should need to), you can do this:
var div = document.getElementById('01');
div.id = 'new_id';

Nice and easy.

I hope this helps and I haven't completely missed the question.

All the best.

Daz.

Yes, but, 01 is an illegal ID. ID'es can't begin with a number.

document.write(result[result.length-2]);

will give you the folder name.

<script type="text/javascript">
fullpath=location.pathname;
result=fullpath.split("\/");
document.write('<div id="' + result[result.length-2] + '">);
</script>

He doesn't want a pointer, he wants to assign the id to it.

document.getElementById('someDiv').id = newID;

That isn't a "rule of thumb" though, it is a rule of the specs that
ID'es can't begin with a number.

Thanx so much Daz & Randy... I've learned that 01 is an illegal ID name

well, my english is not the best so excuse me.

What I meant is easy to think but difficult to write

I want to change the ID value in a DIV. This value should be the same value
of the directory name where the file is allocated.

I try again with an example:

I have the file "example.html"
It is in a place in the web, for example the url is:
http://www.siteweb.com/directory/aboutus/example.html

so... in the htlm I have a DIV that inclused other stuff... for example:

<div id="JAVA">

some other code here

</div>


well... I need to change the value JAVA with the name of the subfolder
"aboutus" that is the name of the folder where example.html is

So if I will change the name of the subfolder in "contacts" the value JAVA
will be automatically changed.

Hope that's clear enough
Sooo sorry for my english

Luca

My first reply shows how to get the folder name. My reply to Daz shows
how to set the ID attribute after it has loaded.

fullpath=location.pathname;
result=fullpath.split("\/");
document.getElementById('JAVA').id = result[result.length-2];
