JS obtenha o parâmetro URL
const queryString = window.location.search;
const urlParams = new URLSearchParams(queryString);
const code = urlParams.get('code')
Awful Anaconda
const queryString = window.location.search;
const urlParams = new URLSearchParams(queryString);
const code = urlParams.get('code')const postID = (new URLSearchParams(window.location.search)).get('post');var getParams = function (url) {
var params = {};
var parser = document.createElement('a');
parser.href = url;
var query = parser.search.substring(1);
var vars = query.split('&');
for (var i = 0; i < vars.length; i++) {
var pair = vars[i].split('=');
params[pair[0]] = decodeURIComponent(pair[1]);
}
return params;
};
