<!--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 --> 看看状态栏的效果啊! <SCRIPT LANGUAGE="JavaScript"> <!-- var flasher = false // calculate current time, determine flasher state, // and insert time into status bar every second function updateTime() { var now = new Date() var theHour = now.getHours() var theMin = now.getMinutes() var theTime = "" + ((theHour > 12) ? theHour - 12 : theHour) theTime += ((theMin < 10) ? ":0" : ":") + theMin theTime += ((flasher) ? " " : " =") theTime += (theHour >= 12) ? " 下午" : " 上午" flasher = !flasher window.status = theTime // recursively call this function every second to keep timer going timerID = setTimeout("updateTime()",1000) } //--> </SCRIPT> <!--第二步：把“onLoad="updateTime()"”加在<body>标记里 例如：--> <body onLoad="updateTime()">
