Turnaround to face the large timer display in the world and look for the controls on the ground. To adjust the time, select or interact with the timer control buttons to add or subject time in 1, 5, and 10-minute increments. Once the timer is set and your teams are chosen, you're...
let intervalId; function startTimer() { intervalId = setInterval(() => { // 执行任务 }, 1000); } function stopTimer() { if (intervalId) { clearInterval(intervalId); intervalId = null; } } 2.定时器不准确 原因:由于JavaScript是单线程的,如果主线程被其他任务占用,setInterval的执行可能会...
