JavaScript: Get an object containing the parameters of the current URL

JavaScript fundamental (ES6 Syntax): Exercise-51 with Solution

Write a JavaScript program to get an object containing the current URL parameters.

  • 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.

Sample Solution:

JavaScript Code:

//#Source https://bit.ly/2neWfJ2 
  const get_URL_Parameters = url =>
  (url.match(/([^?=&]+)(=([^&]*))/g) || []).reduce(
    (a, v) => ((a[v.slice(0, v.indexOf('='))] = v.slice(v.indexOf('=') + 1)), a),
    {}
  );
console.log(get_URL_Parameters('http://url.com/page?name=Adam&surname=Smith')); 
console.log(get_URL_Parameters('google.com'));
console.log(get_URL_Parameters('https://www.w3resource.com'));

Sample Output:

{"name":"Adam","surname":"Smith"}
{}
{}
