JS根据当天不同时间显示不同广告的代码

var h = new Date().getHours();
var t = "";
if(h >= 6 && h <= 12){
        t = "广告1";        
}else if(h >= 14 && h <= 20){
        t = "广告2";
}
  else if(h >= 21 || h <= 6){
        t = "广告3";
  }
document.getElementById('time_ads').innerhtml = t;

<script type="text/javascript">
var h = new Date().getHours();
var t = "";
if(h >= 7 && h <= 13){
        t = "<div class='inde_t_ad'><a href='/file/imgs/upload/202302/09/pmwoa0ot2nh.jpg' border='0' /></a></div>";        
}else if(h >= 14 && h <= 20){
        t = "广告2";
}
  else if(h >= 21 || h <= 6){
        t = "广告3";
