js获取当前时间

let time = new Date()
console.log(time) //打印结果为：Wed Aug 31 2022 10:47:48 GMT+0800 (中国标准时间)
console.log(time.toLocaleString()) //打印结果为：2022/8/31 10:49:41
console.log(time.toLocaleDateString()) //打印结果为：2022/8/31
console.log(time.toDateString()) //打印结果为：Wed Aug 31 2022
console.log(time.toLocaleTimeString()) //打印结果为：10:53:04
console.log(time.toTimeString()) //打印结果为：10:54:25 GMT+0800 (中国标准时间)

如果有一个需求，需要将当前日期格式化为yyyy-MM-dd  hh:mm:ss

 

function timestampToTime(times) {
let time = times[1]
let mdy = times[0]
mdy = mdy.split('/')
let month = parseInt(mdy[0]);
let day = parseInt(mdy[1]);
let year = parseInt(mdy[2])
return year + '-' + month + '-' + day + ' ' + time
}
let time = new Date()
let nowTime = timestampToTime(time.toLocaleString('en-US',{hour12: false}).split(" "))
console.log(nowTime)
//打印结果为：2022-8-31 11:08:34
