Answer 1

使用setTimeout() function

示例：

setTimeout(() => { // function

console.log('This will be logged after five seconds')

}, 5000) // amount of time to wait in ms. for this example I used five seconds (5000 ms)

具有排程功能的示例：

function schedule(time, triggerThis) {
    // get hour and minute from hour:minute param received, ex.: '16:00'
    const hour = Number(time.split(':')[0]);
    const minute = Number(time.split(':')[1]);

    // create a Date object at the desired timepoint
    const startTime = new Date();
    startTime.setHours(hour, minute);
    const now = new Date();

    // increase timepoint by 24 hours if in the past
    if (startTime.getTime() < now.getTime()) {
      startTime.setHours(startTime.getHours() + 24);
    }

    // get the interval in ms from now to the timepoint when to trigger the alarm
    const firstTriggerAfterMs = startTime.getTime() - now.getTime();

    // trigger the function triggerThis() at the timepoint
    // create setInterval when the timepoint is reached to trigger it every day at this timepoint
    setTimeout(function () {
      triggerThis();
      setInterval(triggerThis, 24 * 60 * 60 * 1000);
    }, firstTriggerAfterMs);
  }
  
  schedule('14:00', () => {
  //        ^^^^^ time to trigger function
  
  // send message
  client.channels.cache.get(id) // id of channel you want to send message in
  .send('this is a message')
  })
