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 id="reload1"></script>

</head><small>
<div id="p_show></div>

</small>

XXXXX.php

<?php
header("Cache-Control: no-cache, must-revalidate");
 echo "document.all.p_show.innerHTML= \"?<font color=red>".rand(0,9)."</font>\"";
?>
