本篇文章给大家分享的是关于JS实现实时显示时间，有感兴趣的朋友可以看一看，有需要帮助的朋友也可以参考一下
在之前的项目中有做到需要在网页中实时显示当前时间，实现的效果如图所示：
1. html结构
<p class="col-xs-12 col-sm-6">
<i class="fa fa-plus-square-o" aria-hidden="true"></i>
<span id="current-time"></span>
</p>2. JS
/*实时显示时间*/
function showtime(){
var today,hour,second,minute,year,month,date;
var strDate ;
today=new Date();
var n_day = today.getDay();
switch (n_day){
case 0:{
strDate = "星期日"
}break;
case 1:{
strDate = "星期一"
}break;
case 2:{
strDate ="星期二"
}break;
case 3:{
strDate = "星期三"
}break;
case 4:{
strDate = "星期四"
}break;
case 5:{
strDate = "星期五"
}break;
case 6:{
strDate = "星期六"
}break;
case 7:{
strDate = "星期日"
}break;
}
year = today.getFullYear();
month = today.getMonth()+1;
date = today.getDate();
hour = today.getHours();
minute =today.getMinutes();
second = today.getSeconds();
if (month >= 1 && month <= 9) {
month = "0" + month;
}
if (date >= 0 && date <= 9) {
date = "0" + date;
}
if (hour >= 0 && hour <= 9) {
hour = "0" + hour;
}
if (minute >= 0 && minute <= 9) {
minute = "0" + minute;
}
if (second >= 0 && second <= 9) {
second = "0" + second;
}
document.getElementById('current-time').innerHTML ="当前时间："+ year + "年" + month + "月" + date + "日" +" "+ strDate +" " + hour + ":" + minute + ":" + second; //显示时间
setTimeout("showtime();", 1000); //设定函数自动执行时间为 1000 ms(1 s)
