See the Pen JavaScript current day and time - basic-ex-2 by w3resource (@w3resource) on CodePen.Explanations: Declaring a JavaScript date : In JavaScript Date objects are based on a time value that is the number of milliseconds since 1 January, 1970 UTC. You can declare a date in the...

Date 对象基于 Unix Time Stamp,即自 1970 年 1 月 1 日(UTC)起经过的毫秒数。其语法如下: 复制 newDate();newDate(value);newDate(dateString);newDate(year,monthIndex[,day[,hours[,minutes[,seconds[,milliseconds]]]); 1. 2. 3. 4.
countTimeout.value++ addCount() }, 1000) } addCount() const stopTimeout = () => { console.log('ClearInterval triggered in stopTimeout method!') clearInterval(TimeoutID) } </script> 但为了避免代码杂乱无章、保证代码的可维护性,还是更推荐使用相互匹配的clearInterval()和clearTimeout()。
