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>------解决方案--------------------
我之前做过类似东西，好像还可以搜索到
