计时器达到0时如何触发功能？

Question

I'm currently working on a short quiz game but I cant seem to figure it out. I feel like I have everything that I need, but I may have possibly placed them in a wrong order?

JS:

function stopTimer() {
    clearInterval(intervalID);
}

function startTimer() {
    intervalID = window.setInterval(function() {
        animations()
    }, 1000);
    time = 30;
}

animations = function() {
    time--;
    if (time >= 0) {
        timer.textContent = time;
    } else if (time == 0) {
        EndToAlert(); //*This is the function im trying to fire once timer 
        reaches 0 * //
            stopTimer();
    }
}

Answer 1

使用if (time == 0)而不是else if (time == 0) ，因为当time = 0时，将执行上面的if (time >= 0) ，但是else if (time == 0)不会执行。

Answer 2

只是将else如果（time == 0）更改为else。
