个人感觉完全为了Ajax而Ajax就不好了！JavaScript在客户端处理不是更理想吗?

复制代码 代码如下:

function Timer(span)

{

var tmp = new Date();

var milsecs=Date.parse(tmp.getMonth()+"-"+tmp.getDay()+"-"+tmp.getFullYear()+" "+document.getElementById('lbl_Hour').innerText+":"+document.getElementById('lbl_Minute').innerText+":"+document.getElementById('lbl_Second').innerText);

var timer = new Date(milsecs+span);

var seconds,minutes,hours,date;

if(timer.getSeconds()<10)

seconds = "0"+timer.getSeconds();

else

seconds = timer.getSeconds();

if(timer.getMinutes()<10)

minutes = "0"+timer.getMinutes();

else

minutes = timer.getMinutes();

if(timer.getHours()<10)

hours = "0"+timer.getHours();

else

hours = timer.getHours();

date=timer.getDate();

document.getElementById('lbl_Second').innerText = seconds;

document.getElementById('lbl_Minute').innerText = minutes;

document.getElementById('lbl_Hour').innerText = hours;

}

//得到服务器时间每隔updatespan分钟校验一次，每秒更新一次本地时钟

function GetServerTime(updatespan)

{

var clientspan = 1*1000;

//更新本地时钟

setInterval("Timer("+clientspan+")",clientspan);

//同步服务器时钟

setInterval("window.location.href='当前URL'", updatespan);

}
