利用php和js实现页面数据刷新

利用"XXXX.htm"和"XXX.php"两个文件来实现数据的刷新

XXXX.htm

<head>

<script>

// Refresh code

r_s = 0;

timenow = 0;

function calrs()

{

d = new Date();

h= d.getHours(); m = d.getMinutes(); s = d.getSeconds();

if( m < 10) m = '0' + m;

if( s < 10) s = '0' + s;

status = ' ' + h + ":" + m + ":" + s;

r_s = 2000;

}

calrs();

function reload_me()

{

c = document.getElementById("reload1");

c.src = "";

c.src = "XXXXX.php?reload=1";

calrs();

setTimeout('reload_me()', r_s);

}

// Refresh code

setTimeout('reload_me()', r_s);

</script>

<script ></script>
