是这个吗?但是怎么用啊

Answer 1

<script> 
setInterval("refreshTime()",1000); //每格1秒Z新一次 
funciton refreshTime() 
{ 
var dateObj = new Date(); 
time.innerHTML = dateObj.toLocaleDateString(); 
} 
</script> 
<?php
$time=date("Y-m-d H:i:s");
?>
<div id=time><?php echo $time;?></div>这个简单的例子应该怎么改改啊,才能让它自动刷新!

Answer 2

获取time,用innerHTML重写就行了
