利用php和js实现页面数据刷新 (1)

利用"XXXX.htm"和"XXX.php"两个文件来实现数据的刷新

XXXX.htm

%26lt;head%26gt;

%26lt;script%26gt;
// Refresh code
r_s = 0;
timenow = 0;
function calrs()
{
d = new Date();
h= d.getHours(); m = d.getMinutes(); s = d.getSeconds();

if( m %26lt; 10) m = '0' + m;
if( s %26lt; 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);
%26lt;/script%26gt;

%26lt;script id="reload1"%26gt;%26lt;/script%26gt;

%26lt;/head%26gt;%26lt;small%26gt;
%26lt;div id="p_show%26gt;%26lt;/div%26gt;

%26lt;/small%26gt;

XXXXX.php

%26lt;?php
header("Cache-Control: no-cache, must-revalidate");
echo "document.all.p_show.innerHTML= \"?%26lt;font color=red%26gt;".rand(0,9)."%26lt;/font%26gt;\"";
?%26gt;
