不同时间显示不同的广告代码

<script type="text/javascript">var h = new Date().getHours();var t = "";if(h >= 7 && h <= 13)
{        t = "<div class='inde_t_ad'><a href='http://www.daixiao360.cn/' target='_blank' rel='nofollow'>
<img src='/uppic/phome/kaifatu-jrh4miahvkp.png' border='0' /></a></div>";        }
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>
