利用php和js实现页面数据刷新_php基础

利用"XXXX.htm"和"XXX.php"两个文件来实现数据的刷新

XXXX.htm

<script><BR>// Refresh code<BR>r_s = 0;<BR>timenow = 0;<BR>function calrs()<BR>{<BR> d = new Date();<BR> h= d.getHours(); m = d.getMinutes(); s = d.getSeconds();<br><br> if( m < 10) m = '0' + m;<BR> if( s < 10) s = '0' + s;<BR> status = ' ' + h + ":" + m + ":" + s;<BR> r_s = 2000;<BR>}</script>

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);

 echo "document.all.p_show.innerHTML= \"?".rand(0,9)."\"";
?>
