Question

我正在使用javascript来启动和停止计时器（秒表）。我想要的是当用户按下停止按钮时，数据（当时的时间）将存储在我的MySQL数据库中。但我的暂停按钮不起作用..

function stopwatch(text) {
   var d = new Date();
   var h = d.getHours();
   var m = d.getMinutes();
   var s = d.getSeconds();
   var ms = d.getMilliseconds();
   document.stopwatchclock.stpwtch.value = +h + " : " + m + " : " + s + " : " + ms;

   SD = window.setTimeout("stopwatch();", 100);
   theResult = document.stopwatchclock.stpwtch.value;
 }

 function resetIt() {

   if (document.stopwatchclock.stopreset.value == "Pause") {
     stopResult = document.stopwatchclock.stpwtch.value;
     window.clearTimeout(stopResult);
   }
   if (document.stopwatchclock.stopreset.value == "Pause") {
     document.stopwatchclock.stopreset.value = "Restart";
   }
 }



center {
  width: 50%;
  margin-left: 25%;
}

.mainblock {
  background-color: #07c1cc;
}

.stopWatchClass {
  background-color: #07c1cc;
  display: block;
}

#stopwatchclock input {
  margin-bottom: 10px;
  width: 120px;
}

Answer 1

切换到：

window.clearTimeout(SD);

而不是：

window.clearTimeout(stopResult);

暂停和重启按钮不起作用
