本文实例为大家分享了html获取系统当前时间的具体代码，供大家参考，具体内容如下
td {
font-size: 12px; color: #ffffff; font-family: verdana, arial, helvetica, sans-serif
}
function tick() {
var years,months,days,hours, minutes, seconds;
var intyears,intmonths,intdays,inthours, intminutes, intseconds;
var today;
today = new date(); //系统当前时间
intyears = today.getfullyear(); //得到年份,getfullyear()比getyear()更普适
intmonths = today.getmonth() + 1; //得到月份，要加1
intdays = today.getdate(); //得到日期
inthours = today.gethours(); //得到小时
intminutes = today.getminutes(); //得到分钟
intseconds = today.getseconds(); //得到秒钟
years = intyears + "-";
if(intmonths < 10 ){
months = "0" + intmonths +"-";
} else {
months = intmonths +"-";
}
if(intdays < 10 ){
days = "0" + intdays +" ";
} else {
days = intdays + " ";
}
if (inthours == 0) {
hours = "00:";
} else if (inthours < 10) {
hours = "0" + inthours+":";
} else {
hours = inthours + ":";
}
if (intminutes < 10) {
minutes = "0"+intminutes+":";
} else {
minutes = intminutes+":";
}
if (intseconds < 10) {
seconds = "0"+intseconds+" ";
} else {
seconds = intseconds+" ";
}
timestring = years+months+days+hours+minutes+seconds;
clock.innerhtml = timestring;
window.settimeout("tick();", 1000);
}
window.onload = tick;
