[JS] Recupérer QueryString d'une URL

Ancienne méthode

function getParameterByName(name, url) {

if (!url) url = window.location.href;

name = name.replace(/[\[\]]/g, "\\$&");

var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)"),

results = regex.exec(url);

if (!results) return null;

if (!results[2]) return '';

return decodeURIComponent(results[2].replace(/\+/g, " "));

}

Utilisation

// query string: ?foo=lorem&bar=&flp

var foo = getParameterByName('foo'); // "lorem"

var bar = getParameterByName('bar'); // "" (present with empty value)

var flp = getParameterByName('flp'); // "" (present with no value)

var ogr = getParameterByName('ogr'); // null (absent)

Nouvelle méthode basé sur : URLSearchParams

#Browser url: http://www.example.com/?anything=123

var searchParams = new URLSearchParams(window.location.search); //?anything=123

console.log(searchParams.get("anything")) //123
