之前弄了一个倒计时代码 有两个问题
1. 刷新之后 倒计时还是挺顺的 但是等个半分钟，倒计时就开始卡 然后就不动了，这是为什么？
2. 卡了之后再点刷新，网页没反应，除非把这个页面关了 重新打开，然后重复第一个问题。。
代码如下：
- PHP code
<script language="JavaScript">
function getTheTime(D,i){
var theDate=new Date(D);
var date = new Date();
var diffTime = theDate - date;
//if(diffTime<=0){
//document.getElementById("diffDay2"+i) .innerHTML="时间已过.";
//return;
//}
var para = 1000 * 60 * 60 * 24;
var diffday = diffTime / para;
var diffHour = (diffTime % para) / 3600000;
var diffMinute = (diffTime % 3600000 ) / 60000;
var diffSecond = (diffTime % 60000) / 1000;
//document.getElementById("diffDay1"+i).innerHTML = "<b>"+Math.floor(diffday)+ "</b>" + "天 ";
document.getElementById("h_diffDay2"+i).innerHTML = Math.floor(diffHour);
document.getElementById("m_diffDay2"+i).innerHTML = Math.floor(diffMinute);
document.getElementById("s_diffDay2"+i).innerHTML = Math.floor(diffSecond);
setInterval("getTheTime('" + D + "'," + i + ")", 1000);
}
</javascript>
<table style="width:80%; margin:auto" border="0">
<tr><td class="txt_d_cd" style="color:#d34836">Deadline</td><td class="txt_d_cd" colspan="3">Countdown For <strong style="color:#d34836">Dinner</strong></td></tr>
<?php
$query="SELECT * FROM PICKUPTIME ORDER BY deadline ASC";
$sql=queryMysql($query);
$i=0;
while($info=mysql_fetch_array($sql))
{
$deadline_dinner=$info['deadline'];
if($info['deadline'] == "") continue;
//echo $info['deadline'];
$time_hr=substr($deadline_dinner, 0, 2);
$time_min=substr($deadline_dinner, 2, 4);
$pickup_time_formatted=$time_hr.":".$time_min;
//$c_date=date("Y-m-d");
$deadline=date("Y-m-d")." "."$pickup_time_formatted";
$current_time=date("Y-m-d H:i:s");
if($deadline<$current_time)
{
$deadline=date("Y-m-d", strtotime('+1 day'))." "."$pickup_time_formatted";
$dinner_notice="TOMORROW";
}
else
{
$dinner_notice="TODAY";
}
//echo "$deadline";
?>
<tr>
<td class="txt_d_cd"><?php echo "$dinner_notice $pickup_time_formatted"; ?></td>
<td class="txt_cd"><strong id="h_diffDay2<?php echo $i;?>"></strong>h</td>
<td class="txt_cd"><strong id="m_diffDay2<?php echo $i;?>"></strong>m</td>
<td class="txt_cd"><strong id="s_diffDay2<?php echo $i;?>"></strong>s</td>
</tr>
<script type="text/javascript">
getTheTime("<?php echo $deadline;?>",<?php echo $i;?>);
</script>
<?php
$i++;
}
?>
</table>

我之前做过类似东西，好像还可以搜索到
