StopWatch is not working when I click on Stop Button

问题

这是你提供的代码的翻译：

// 开始按钮点击事件

  start.style.display = "none";

  // 毫秒开始
  miliSecondStop = setInterval(() => {
    let miliSec = miliSecStart + 1;
    milisecond.innerText = miliSec;
    miliSecStart = miliSec;
    if (miliSecStart === 99) {
      miliSecStart = 0;
    }
  }, 10);

  // 秒开始
  secondStop = setInterval(() => {

    secStart = sec;

    hourStart = hour;
    if (hour === 24) {
      hourStart = 0;
    }
  }, 60000);
});

// 停止按钮点击事件

得分: 1

你应该使用一个定时器来计数。
你的代码对于秒数也无法正常工作。
如果你快速点击启动和停止，秒数标签不会增加。
这是因为当你点击启动和停止时，所有计时器都会被重置。
所以你应该使用一个定时器。

英文:

You should use one timer to count.
Your code does not work exactly for second too.
If you click start and stop quickly, scond label will not increase.
It's because when you click start and stop, all timer will be reset.
So you should use one timer.

let start = document.getElementById(&quot;start&quot;);
let stop = document.getElementById(&quot;stop&quot;);
let reset = document.getElementById(&quot;reset&quot;);
let h3 = document.getElementById(&quot;h3&quot;);
let time = document.getElementById(&quot;time&quot;);
let h3CreateMin = document.createElement(&quot;h3&quot;);

let second = document.getElementById(&quot;second&quot;);
let minSpan = document.createElement(&quot;span&quot;);
let minSpanSigin = document.createElement(&quot;span&quot;);
let hourSpan = document.createElement(&quot;span&quot;);
let hourSpanSigin = document.createElement(&quot;span&quot;);    
let miliSec = 0;
let s = true;
start.addEventListener(&quot;click&quot;, function () {
reset.style.display = &quot;block&quot;;
stop.style.display = &quot;block&quot;;
start.style.display = &quot;none&quot;;
miliSecondStop = setInterval(() =&gt; {
miliSec++;
let milsecText =  miliSec % 100;
let secText = (parseInt(miliSec / 100)) % 60;
let minText = (parseInt(miliSec / 6000)) % 60;
let hourText = parseInt(miliSec / 360000);
milisecond.innerText = milsecText;      
second.innerText = secText;       
if(minText&gt;0){
time.prepend(h3CreateMin);
h3CreateMin.style.display = &quot;block&quot;;
h3CreateMin.append(minSpan);
minSpan.classList = &quot;value&quot;;

minSpanSigin.classList = &quot;sigin&quot;;
minSpanSigin.innerText = &quot;M&quot;;
minSpan.innerText = minText;   
}
if(hourText &gt; 0){
time.prepend(h3CreateHour);
h3CreateHour.style.display = &quot;block&quot;;
h3CreateHour.classList = &quot;time_s_m_h&quot;;
