在Javascript Timer中显示总分和秒

Question

到目前为止我所做的一切都很好用，虽然我想要一个显示计时器上使用的时间的警报。

例如，在 00:10 启动计时器并在 -00：20 停止，消息提示应该说 30秒

我的问题是\UFFFFFFFF这是STOP按钮，点击它会显示秒数，分钟，但是我遇到了麻烦。

如果客户那么久，我怎么能在那里形成分钟？ JsFiddle

stopTimer()

Answer 1

Confusion caused by counting seconds backwards seems to be the problem. On the fiddle in function stopTimer() changing

    if (seconds > 60) { // .... more than a minute

to

    if(seconds < -60) { // ... more than a minute

causes code for over a minute to get executed (which as written has errors and will need debugging). To clarify the logic and make coding easier when counting backwards may I suggest calculating something like

   var elapsedSeconds = - (seconds - totseconds);
