1.格式一: 08-10-17 09:08:36
<SCRIPT language=javascript type=text/javascript>
function getDate()
{
var d,s,t;
d=new Date();
s=d.getFullYear().toString(10).slice(-2)+"-";
t=d.getMonth()+1;
s+=(t>9?"":"0")+t+"-";
t=d.getDate();
s+=(t>9?"":"0")+t+" ";
t=d.getHours();
s+=(t>9?"":"0")+t+":";
t=d.getMinutes();
s+=(t>9?"":"0")+t+":";
t=d.getSeconds();
s+=(t>9?"":"0")+t;
return s;
}
alert(getDate());//返回的是08-10-17 09:08:36
</SCRIPT>

2.格式二: 2008-10-17 09:08:36
<SCRIPT language=javascript type=text/javascript>
function getDate()
{
var d,s,t;
d=new Date();
s=d.getFullYear().toString(10)+"-";
t=d.getMonth()+1;
s+=(t>9?"":"0")+t+"-";
t=d.getDate();
s+=(t>9?"":"0")+t+" ";
t=d.getHours();
s+=(t>9?"":"0")+t+":";
t=d.getMinutes();
s+=(t>9?"":"0")+t+":";
t=d.getSeconds();
s+=(t>9?"":"0")+t;
return s;
}
alert(getDate());//返回的是2008-10-17 09:08:36
</SCRIPT>

3.格式三： 2008-10-17 09:08:36.789
<SCRIPT language=javascript type=text/javascript>
function getDate()
{
var d, ret;
d = new Date();
ret = d.getFullYear()+"-";
ret += ("00"+(d.getMonth()+1)).slice(-2)+"-";
ret += ("00"+d.getDate()).slice(-2)+" ";
ret += ("00"+d.getHours()).slice(-2)+":";
ret += ("00"+d.getMinutes()).slice(-2)+":";
ret += ("00"+d.getSeconds()).slice(-2)+".";
ret += d.getMilliseconds();
return ret;
}
alert(getDate());//返回的是2008-10-17 09:08:36.789
</SCRIPT>
