是不是用SESSION?
有会话到会话关闭就是在线的时间.
我猜的
页面停留时间1[共2步]
====1、将以下代码加入HTML的<head></head>之间:
<SCRIPT
LANGUAGE="JAVASCRIPT">
<!--
var ap_name = navigator.appName;
var
ap_vinfo = navigator.appVersion;
var ap_ver =
parseFloat(ap_vinfo.substring(0,ap_vinfo.indexOf('(')));
var time_start = new
Date();
var clock_start = time_start.getTime();
var
dl_ok=false;
function init ()
{
if(ap_name=="Netscape" &&
ap_ver>=3.0)
dl_ok=true;
return true;
}
function get_time_spent
()
{
var time_now = new Date();
return((time_now.getTime() -
clock_start)/1000);
}
function show_secs () // show the time user spent
on the side
{
var i_total_secs = Math.round(get_time_spent());
var
i_secs_spent = i_total_secs % 60;
var i_mins_spent =
Math.round((i_total_secs-30)/60);
var s_secs_spent = "" +
((i_secs_spent>9) ? i_secs_spent : "0" + i_secs_spent);
var s_mins_spent
="" + ((i_mins_spent>9) ? i_mins_spent : "0" +
i_mins_spent);
document.fm0.time_spent.value = s_mins_spent + ":" +
s_secs_spent;
window.setTimeout('show_secs()',1000);
}
//
-->
</SCRIPT>
====2、将以下代码加入HTML的<body></body>之间:
<BODY
onLoad="init(); window.setTimeout('show_secs()',1);">
<form name="fm0"
onSubmit="0">
<font size="-1"><I><FONT
COLOR="#888888">您在本网页的停留时间:</FONT></I></font><br>
<INPUT
type="text" name="time_spent" size=7 onFocus="this.blur()">
</form>
页面停留时间2[离开时弹出提示框][共1步]
====1、将以下代码加入HEML的<body></body>之间:
<script
LANGUAGE="Javascript">
<!-- Begin
pageOpen = new Date();
function
bye() {
pageClose = new Date();
minutes = (pageClose.getMinutes() -
pageOpen.getMinutes());
seconds = (pageClose.getSeconds() -
pageOpen.getSeconds());
time = (seconds + (minutes * 60));
if (time == 1)
{
time = (time + " second");
}
else {
time = (time + "
seconds");
}
alert('您在本页停留了' + time + '.谢谢!!');
}
// End
-->
</script>
<body onUnload="bye()">
