javascript - 格式化时间hh :mm:ss

Question

如何按时设置格式？它显示 16:9:2它应该显示 16:09:02

我的代码:

setInterval(function _timer() {

var time = new Date();
var h = time.getHours();
var m = time.getMinutes();
var s = time.getSeconds();
var fullTime = h + ":" + m + ":" + s;
fullTime.format("hh-MM-ss");// this is not working
$("#time").html(fullTime);

1000

});

你可以这样试试:

var time = new Date();
var h = time.getHours();
var m = time.getMinutes();
var s = time.getSeconds();
alert(
        ("0" + h).slice(-2)   + ":" + 
        ("0" + m).slice(-2) + ":" + 
        ("0" + s).slice(-2));
