Need to re-write the javascript code into tampermonkey script

as I have a javascript code in ASP server pages and the page starts with a count down timer of 120 seconds and after countdown, it shows register button. Here is the code :-

var interval;

function countDown() {




var timer = function () {

var counter = 121;

interval = setInterval(function () {


[login to view URL]("btnRegister").disabled = true;

[login to view URL]("btnRegister").[login to view URL] = 'none';

[login to view URL]('lbltime').innerHTML = "Timer : " + counter;

if (counter == 0) {

[login to view URL]("btnRegister").disabled = false;

[login to view URL]("btnRegister").[login to view URL] = 'Block';

[login to view URL]('lbltime').[login to view URL] = 'none';



}, 1000);


So, what I want to do is, I have to re-write this code, for example I need to set the counter=10 instead of 121 and this has to happen outside the server pages like I want to use tampermonkey or greasemonkey extension and when the page opens, this tampermonkey script has to rewrite the server page script and has to shpw 10 counter instead of 121.
