By using this code remove the last element from the Url link.
url.substring(0, url.lastIndexOf('/'));
Explanation: Explode by "/", remove the last element with pop, join again with "/".
function RemoveLastDirectoryPartOf(the_url)
{
var the_arr = the_url.split('/');
the_arr.pop();
return( the_arr.join('/') );
}

Another way to remove the end of directory path:
path.normalize(path.join(thePath, '..'));
Here is some code that correctly handles /, "", foo and /foo (returning /, "", foo, and / respectively):
function parentDirectory(dir: string): string {
const lastSlash = dir.lastIndexOf('/');
if (lastSlash === -1) {
return dir;
}
if (lastSlash === 0) {
return '/';
}
return dir.substring(0, lastSlash);
}
Just remove the :strings for Javascript. Maybe you want different behaviour but you should at least consider these edge cases.
Sticking to native libraries, dirname could be helpful.
In node (backend)
const path = require('path')
let str='
console.log(path.dirname(n))
console.log(path.dirname(n)+'/')
The output is
'
'
In the Firefox browser (see MDN, Path Manupluation, OS.Path.dirname])
let str='
console.log(OS.path.dirname(n))
console.log(OS.path.dirname(n)+'/')
Sorry but couldn't find anything for Chromium, but maybe I just didn't look hard enough.
