Question

How can I get the URL Path of the current site, but without the last segment:

http://www.domain.com/first/second/last

I only need http://www.domain.com/first/second … with jQuery (or only JavaScript)

Answer 1

Using pop and URL api

this assumes the URL is not likely to change

I use document.URL since that is what is recommended

const url = new URL("https://www.example.com/first/second/last"); // new URL(document.URL)
let path = url.pathname.split("/");
path.pop(); // remove the last
url.pathname = path.join("/")
console.log(url)

Older answers: As requested by OP – with changes from comment

const url = "http://www.example.com/first/second/last", // document.URL, 
    shortUrl=url.substring(0,url.lastIndexOf("/"));
console.log(shortUrl)    

Here is an alternative

const url = new URL("http://www.example.com/first/second/last"),
      shortUrl = `${url.protocol}//${url.hostname}${url.pathname.slice(0,url.pathname.lastIndexOf("/"))}`

console.log(shortUrl)
