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. – kelsny Nov 07 '22 at 23:17

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
