请注意下面的状态栏
第一步：拷贝下面的代码到你的html文件的<head>和</head>之间；
<script Language="JavaScript"> 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) ? " P.M." : " A.M." window.status = timeValue; timerID = setTimeout("showtime()",1000); timerRunning = true; } function startclock () { stopclock(); showtime(); } </script>
第二步：修改你的<body>语句为；<BODY onLoad="startclock()">
