请写一个长宽为150px的div并用Js设置内容为当前的日期和时间

<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>
