getURLParameters

JavaScript, Browser, String, Regexp

Creates an object containing the parameters of the current URL.

  • Use String.prototype.match() with an appropriate regular expression to get all key-value pairs.
  • Use Array.prototype.reduce() to map and combine them into a single object.
  • Pass location.search as the argument to apply to the current url.
const getURLParameters = url =>
  (url.match(/([^?=&]+)(=([^&]*))/g) || []).reduce(
    (a, v) => (
      (a[v.slice(0, v.indexOf('='))] = v.slice(v.indexOf('=') + 1)), a
    ),
    {}
  );
getURLParameters('google.com'); // {}
getURLParameters('http://url.com/page?name=Adam&surname=Smith');
// {name: 'Adam', surname: 'Smith'}
