Question

我的目标是让计时器在指定的时间启动（确实如此），但是我不想要日期（2019年1月29日），我只想要时间，这样我就不必更新日期每一天。关于如何更改for（）在时间而非日期范围内工作的任何建议？

我尝试仅删除日期并留下时间，因此无法使用。

var schedule = [
    ['Jan 29, 2019 20:43:00', 'Jan 29, 2019 21:48:05']
]
<!-- Mainly this part -->
for(var i=0; i<schedule.length; i++){
  var startDate = schedule[i][0];
  var endDate = schedule[i][1];

  // put dates in milliseconds for easy comparisons
  var startMs = Date.parse(startDate);
  var endMs = Date.parse(endDate);
  var currentMs = Date.parse(new Date());

  // if current date is between start and end dates, display clock
   if(endMs > currentMs && currentMs >= startMs ){
      initializeClock('clockdiv', endDate);
      openRequestedPopup();
        myStopFunction();
        setInterval(function(){window.location.reload(5);}, 306000);
        setTimeout(function () { windowObjectReference.close();}, 305000);

}

仅显示带有日期和时间的计时器，我只希望计时器仅显示开始时间和结束时间。

根据我的评论，如果是这样的话，这样的事情应该起作用：

    tsil = ['input',]

while True:
  print('Write A Number (Print "done" When Finished)')
  num = input()
  tsil.append(num)
  print()
  if num == 'done':
    break

if True == True:
  print(tsil)

def a():
  print('you like short lists? (True or False)')
  ans = input()
  if ans == 'True' or 'true':
    return '\ngood for you'
  elif ans == 'False' or 'false':
    return '\nstop making short lists then'
  else:
    return '\nstop printing the wrong things loser'


def b():
  print('you like long lists? (True or False)')
  ans = input()
  if ans == 'True' or 'true':
    return '\ngood for you'
  elif ans == 'False' or 'false':
    return '\nstop making short lists then'
  else:
    return '\nstop printing the wrong things loser'

if len(tsil) < 10:
  print('^ short list large gorge')
  print()
  print(a())
else:
  print('^ big boy list')
  print()
  print(b())

var schedule = [
['Jan 30, 2019 10:40:00', 'Jan 30, 2019 12:12:05']
];
for(var i=0; i<schedule.length; i++){
var startDate = schedule[i][0];
var endDate = schedule[i][1];
 // put dates in milliseconds for easy comparisons
var startMs = Date.parse(startDate);
var endMs = Date.parse(endDate);
var currentMs = Date.parse(new Date());

// if current date is between start and end dates, display clock
 if( currentMs >= startMs && currentMs<endMs){ 


  var id =    setInterval(function(){ printTime(); }, 1000);

  function printTime(){
  var time = new Date();
  currentMs = time.getTime();
  var hours = time.getHours();
  var minutes = time.getMinutes();
  var seconds = time.getSeconds();
  document.write(hours + " " + minutes+" " + seconds+" ");


  if(currentMs>=endMs)
    clearInterval(id);  
 }
}

}
