使用 JavaScript 在 div 中显示当前日期和时间

<div id='myDiv' style='width: 150px; height: 150px;'></div>
<script>
  var currentDate = new Date();
  var dateString = currentDate.toLocaleDateString();
  var timeString = currentDate.toLocaleTimeString();
  var dateTimeString = dateString + ' ' + timeString;
  document.getElementById('myDiv').innerHTML = dateTimeString;
</script>
