let say that in our websites we can have urls like:

http://domainame.com/dir/one-simple-name.html
https://dmainame.com/mail/send.php
https://dmainame.com/mail/read

etc..

So i would like to retrieve

dir/one-simple-name
mail/send
mail/read

Whats the best way to achieve it?

Everybody stand back! I know regular expressions! Try this one:

var my_location = window.location.toString().match(/\/\/[^\/]+\/([^\.]+)/)[1];

I would recommend doing this by,

var url = "https://www.somegoodwebsite.com/happy/ending/results/index.html";
console.log(url.replace(/^.*\/\/[^\/]+/, '') );

;

Result:
happy/ending/results/index.html

You can use this:

var result = window.location.pathname.replace(/\.[^\.\/]+$/, "").substr(1);

In javascript, you can access the various parts of the URL via the window.location object.

window.location.href - the entire URL 
window.location.host - the hostname and port number - [www.sample.com]:80
window.location.hostname - the hostname - www.sample.com
window.location.pathname - just the path part - /search
window.location.search - the part of the URL after the ? symbol - ?q=demo

In your case, you can use window.location.pathname and then if you need to strip the file extension off the filename, you can do that with some additional javascript:

var result = window.location.pathname.replace(/\.[^\.\/]+$/, "").substr(1);

This line of javascript will get the pathname component of the URL and then replace any file extension with "" (effectively removing it) and the remove the leading slash.

A more jqueryish way than using just regular expressions: 

var path = $('<a>', {href: 'http://google.com/foo/bar.py'})[0].pathname.replace(/\.(.+)$/,'')
