How to Get # URL value with JavaScript

Hatahle

i cant use url Query https://example.com/?l=http://example2.com on my CloudFlare Worker server.

So, My question is, how to convert this JS script to work with https://example.com/#http://example2.com

function getUrlVars() {
    var vars = {};
    var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi,    
    function(m,key,value) {
      vars[key] = value;
    });
    return vars;
  }      

var l = getUrlVars()["l"];
