说明: 在状态栏中显示停留时间

效果: 看本页状态栏

代码:

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()" >
