基于时间的div刷新时间

Question

嘿，你怎么在某个小时刷新一个div？ 因此，基于时间的问候语会自动结算。 我目前的代码是：

<div id = "greet" ><script>
var Digital=new Date()
var hours=Digital.getHours()
if (hours < 12)
document.write('Good morning.')
else if (hours >= 12 && hours < 18) 
// (code in here?) refresh the div at 12:00 pm
document.write('Good afternoon.')
else if (hours >= 18 && hours <= 24)
// (code in here?) refresh div at 6:00 pm
document.write('Good evening.')
</script></div>

任何提示都会很棒。 欢呼声。

你需要这样吗

def test_notebooks():
  for notebook in glob("./*.ipynb"):
    nb, errors = _notebook_run(notebook)
    assert errors == []

var datas="";
var Digital=new Date()
var hours=Digital.getHours()
if (hours < 12){
datas = 12 ? "is a below 12am" : "";
document.write('Good morning.')
}
else if (hours >= 12 && hours < 18) {
   datas = 12 ? "is a 12am" : "";
document.write('Good afternoon.')}
else if (hours >= 18 && hours <= 24){
  datas = 18 ? "is a 6pm" : "";
document.write('Good evening.')
}
document.getElementById('greet').innerHTML=datas;
