要完成此效果需要两个步骤
第一步：把如下代码加入到<head>区域中
<script>
var Temp;
var TimerId = null;
var TimerRunning = false;
Seconds = 0
Minutes = 0
Hours = 0
function showtime()
{
if(Seconds >= 59)
{
Seconds = 0
if(Minutes >= 59)
{
Minutes = 0
if(Hours >= 23)
{
Seconds = 0
Minutes = 0
Hours = 0
}
else {
++Hours
}
}
else {
++Minutes
}
}
else {
++Seconds
}
if(Seconds != 1) { var ss="s" } else { var ss="" }
if(Minutes != 1) { var ms="s" } else { var ms="" }
if(Hours != 1) { var hs="s" } else { var hs="" }
Temp = '你在本页停留了 '+Hours+' 小时'+', '+Minutes+' 分'+', '+Seconds+' 秒'+''
window.status = Temp;
TimerId = setTimeout("showtime()", 1000);
TimerRunning = true;
}
var TimerId = null;
var TimerRunning = false;
function stopClock() {
if(TimerRunning)
clearTimeout(TimerId);
TimerRunning = false;
}
function startClock() {
stopClock();
showtime();
}
function stat(txt) {
window.status = txt;
setTimeout("erase()", 2000);
}
function erase() {
window.status = "";
}
</script>
第二步：把“onLoad="startClock()"”加在<body>标记里
例如：<body onLoad="startClock()">
