本文章提供给大家的是一个学习实例，关于如何在状态上显示时钟，把下面代码放进<body>中就可运行，赶紧来试下吧。
<BODY onLoad="startclock()">
<SCRIPT LANGUAGE=java script>
<!--
var timerID = null;
var timerRunning = false;
function stopclock (){
if(timerRunning)
clearTimeout(timerID);
timerRunning = false;
}
function showtime () {
var now = new Date();
var hours = now.getHours();
var minutes = now.getMinutes();
var seconds = now.getSeconds()
var timeValue = "" + ((hours >12) ? hours -12 :hours)
timeValue += ((minutes < 10) ? ":0" : ":") + minutes
timeValue += ((seconds < 10) ? ":0" : ":") + seconds
timeValue += (hours >= 12) ? " PM." : " AM."
window.status = timeValue;
timerID = setTimeout("showtime()",1000);
timerRunning = true;
}
function startclock () {
stopclock();
showtime();
}
-->
</SCRIPT>
