在运行时编辑Javascript并影响HTML页面上的计时器

Question

I am trying to skip timer placed on an HTLM page. Javascript for the TIMER is below:

var t = 60;
var decr = 1;
var handle = null;
var e = null;
function startTimer() {
    if(!e) e = document.getElementById("time");
    e.innerHTML = t;
    handle = setInterval(function() {
        if(t == 0) {
            clearInterval(handle);
            var answer = confirm("Yes/No?")
            if (answer){
                alert("You Clicked Yes!")
                window.location = "https://twitter.com/";
            }
            else{
                alert("You Clicked No!")
            }
        }
        else {
            t -= decr;
            e.innerHTML = t;
        }
    }, decr * 1000);
}
window.onload = startTimer;

What I want is to change the TIMER to 10 seconds as soon as the page gets loaded. I tried to enter the following code in browser location bar:

javascript:document.getElementById('time').innerHTML = "10";

But I'm not getting into it. What'll be the proper way to do it?

Open the console (development tools). If you are using chrome, press F12, then press console and insert the command

document.getElementById('time').innerHTML = "10";

or

document.getElementById('time').value = "10";

and then press enter.
