停留时间
在头部<head>...</head>之间加入以下代码:
<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>
主体中加入:
<body onLoad="init();
window.setTimeout('show_secs()',1);">
<form name="fm0" onSubmit="0">
<font color="f00000"><b>停留时间：</font></b>
<input type="text" name="time_spent"
size=7 onFocus="this.blur()">
</form>
</body>
