当然,ajax使用起来确实很简单就可以实现,但是里面的很多知识还是比较有点深的。我之前做页面时间自动刷新的功能就是用的ajax。完整代码是:

$dt_element=explode(" ",$time);
$date_element=explode("-",$dt_element[0]);
$time_element=explode(":",$dt_element[1]);
$date = mktime($time_element[0],$time_element[1],$time_element[2],$date_element[1],$date_element[2],$date_element[0]);
$nowTime = time(); 
$showtime = date("北京时间Y年m月d日H:i:s",$date-$nowTime); 
if($showtime echo "happy new year";
}
echo $showtime;

2.zidong.php:
复制代码 代码如下:
