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"} {} {}
