You may use the URLSearchParams class.
const url_params = new URLSearchParams(window.location.search);
const id = url_params.get('id');
console.log(id);

Not so simple. The value in question is
"page.php?id=10&value='hello'", which is an invalid URL search param input. You'll either need some reliable way to get rid of page.php, or build the full URL and use the built-in URL object.for (let name of document.querySelectorAll("a")) {
var Reg = /page.php\?id=(\d+)\&value=%27(.*?)%27/g;
var Array;
while ((Array = Reg.exec(name.href)) != null){
console.log(Array[1]);
console.log(Array[2]);
}
}
regex
