javascript获取登录时间,javascript获取在线时长,javascript动态时间本文实例介绍了javascript动态获取登录时间和在线时长的相应代码，分享给大家供大家参考，具体内容如下 效果图： 
实现代码： <html> <head> <title>online</title> <script language=javaScript> ///这里是获得登录时候的时间，用来和动态的时间做差来求时长 var s = new Date(); function clockon() { var thistime = new Date(); //时间差 diff = new Date(); diff.setTime(Math.abs(thistime.getTime() - s.getTime())); timediff = diff.getTime(); hos = Math.floor(timediff / (1000 * 60 * 60)); mins = Math.floor(timediff / (1000 * 60)); secs = Math.floor(timediff / 1000); //end var hours = thistime.getHours(); var minutes = thistime.getMinutes(); var seconds = thistime.getSeconds(); if (eval(hours) < 10) { hours = "0" + hours; } if (eval(minutes) < 10) { minutes = "0" + minutes; } if (seconds < 10) { seconds = "0" + seconds; } thistime = hours + ":" + minutes + ":" + seconds; bgclockshade.innerHTML = thistime//这里动态的嵌入当前的时间 //如果不取余的话，秒数是一直上升的，所以在达到一个60的时候就取余就可以解决这个问题了 if (secs > 59) { secs = secs % 60; } if (mins > 59) { mins = mins % 60; } if (eval(secs) < 10) { secs = "0" + secs; } if (eval(mins) < 10) { mins = "0" + mins; } if (eval(hos) < 10) { hos = "0" + hos; } jishi.innerHTML = hos + ":" + mins + ":" + secs; var timer = setTimeout("clockon()", 200); }</script> </head> <body onload="clockon();"> 登录时间： <div id="bgclockshade"></div> 上网时长： <div id="jishi"></div> </body></html>以上就是本文的全部内容，希望对大家的学习有所帮助。
