JavaScript 秒表保存在 cookie 中
JavaScript stopwatch saving in cookies
我是 JavaScript 的初学者,我在网站上工作,但我在制作秒表时卡住了。
我需要类似的东西,我在 timer.php 并且我有一个秒表;当我们按下开始时,它从 00:00:00 开始计数,如果我转到 exemple1.php 页,我不希望秒表停止计数,我希望秒表继续计数,当我回到timer.php 秒表一直向前计数,直到我按下停止按钮,当我按下它时,它就停在那个值,例如 00:20:00。
我卡在这里了。在这部分,当我移动到另一个页面时,因为秒表只是停止,我不希望我希望秒表继续计数,当我再次移动到 timer.php 时,我看到秒表在计数并没有停止在 00:00:00.
这是我的代码:
