中文显示的时候保存为.js文件再用网页调用出现乱码。用uft-8编码保存.js文件即可解决乱码问题。

实时游走的数字时钟

<script>
function tick() {
var hours, minutes, seconds, xfile;
var intHours, intMinutes, intSeconds;
var today;
today = new Date();
intHours = today.getHours();
intMinutes = today.getMinutes();
intSeconds = today.getSeconds();
if (intHours == 0) {
hours = "12:";
xfile = "午夜";
} else if (intHours < 12) { 
hours = intHours+":";
xfile = "上午";
} else if (intHours == 12) {
hours = "12:";
xfile = "正午";
} else {
intHours = intHours - 12
hours = intHours + ":";
xfile = "下午";
}
if (intMinutes < 10) {
minutes = "0"+intMinutes+":";
} else {
minutes = intMinutes+":";
}
if (intSeconds < 10) {
seconds = "0"+intSeconds+" ";
} else {
seconds = intSeconds+" ";
} 
timeString = xfile+hours+minutes+seconds;
Clock.innerHTML = timeString;
window.setTimeout("tick();", 100);
}
window.onload = tick;
</script>

第1步.将下面的代码加入html文件任意需要的地方

<div id="Clock" align="center" style="font-size: 20; color:#000000"></div>

你可以自行更改样式！

根据不同的时间显示不同的问候语 
方法：在主页中你需要的地方加入以下代码：

<script language="LiveScript">
now = new Date(),hour = now.getHours()
if(hour < 6){document.write("明天不用上班了吗?")}
else if (hour < 8){document.write("全新的一天!")}
else if (hour < 12){document.write("早安!")}
else if (hour < 14){document.write("外面太阳大吗？")}
else if (hour < 18){document.write("午安!")}
else if (hour < 22){document.write("晚上好!")}
else if (hour < 24){document.write("夜深了! 要注意身体呀! 祝你做个好梦!")}
// -->

说明，可以自行修改出更好更多的问候语！
