在代码块中内置了一个计时器。现在计时器通过按钮启动/停止，但我需要它在释放空格按钮时运行，并且我需要它在按下空格按钮时停止。我已经尝试解决这个问题大约两天了，但似乎找不到解决方案。每次我尝试停止计时器时，当我释放空格按钮时，计时器都会再次启动。

let startDate;
let timeoutID = 0;
let time;
let started = false;
let timerRunOut = false;

function start(){
    if(!started){
        startDate = new Date();
        startTimer();
        started = true;
    }
}
function stop(){
    if(started){
        clearTimeout(timeoutID);
        started = false;
    }
}

function startTimer () {
    let current = new Date();
    time = (current - startDate);

    let timeMS = time;

    let ms = timeMS % 1000;
    timeMS = (timeMS - ms) / 1000;
    let seconds = timeMS % 60;
    timeMS = (timeMS - seconds) / 60;
    let mins = timeMS % 60;

    if(seconds < 10){
        document.getElementById("seconds").innerText = "0" + seconds;
    }else{
        document.getElementById("seconds").innerText = seconds;
    }

    if(mins > 0 && mins < 10){
        document.getElementById("minutes").innerText = "0" + mins + ":";
    }else if(mins > 0){
        document.getElementById("minutes").innerText = mins + ":";
    }else{
        document.getElementById("minutes").innerText = "";
    }

    if(ms < 10){
        document.getElementById("tens").innerText = "00" + ms;
    }
    else if(ms < 100){
        document.getElementById("tens").innerText = "0" + ms;
    }else{
        document.getElementById("tens").innerText = ms;
    }

    timeoutID = setTimeout(startTimer, 0);
}

我尝试添加事件侦听器并添加条件，但没有任何效果，当计时器停止时，当我释放空格按钮时，它总是会再次启动。
