var url ="http://example.com/iu4pa9rm8vfh.html?param_1";
  document.getElementById("demo").innerHTML = 
"The pathname of this page is :" + url.pathname;

    const pathname = url.pathname.match(/([0-9a-z]+)/)
    console.log(pathname[0])

Solution

you can do it like this :

const url = new URL('http://example.com/iu4pa9rm8vfh.html?param_1')
let path = url.pathname.split('.')[0].replace('/','')
document.getElementById("demo").innerHTML = "The pathname of this page is :" + path;

<!DOCTYPE html>
<html>

<body>

  <p id="demo"></p>

  <script>
    const url = new URL('http://example.com/iu4pa9rm8vfh.html?param_1')
    let path = url.pathname.split('.')[0].replace('/','')
    document.getElementById("demo").innerHTML = "The pathname of this page is :" + path;
  </script>

</body>

</html>
