js 时间戳与时间的相互转换
时间戳转换成 “yyyy-MM-dd hh:mm:ss”格式:
happenTimeFun(num){//时间戳数据处理
let date = new Date(num);
//时间戳为10位需*1000,时间戳为13位的话不需乘1000
let y = date.getFullYear();
let MM = date.getMonth() + 1;
MM = MM < 10 ? ('0' + MM) : MM;//月补0
let d = date.getDate();
d = d < 10 ? ('0' + d) : d;//天补0
let h = date.getHours();
h = h < 10 ? ('0' + h) : h;//小时补0
let m = date.getMinutes();
m = m < 10 ? ('0' + m) : m;//分钟补0
let s = date.getSeconds();
s = s < 10 ? ('0' + s) : s;//秒补0
return y + '-' + MM + '-' + d + ' ' + h + ':' + m+ ':' + s;
}
happenTimeFun(1628648245);
“yyyy-MM-dd hh:mm:ss”转换成时间戳:
timeProcessing(){ let timeDate = "2020-08-11 11:08:48"; let Time = new Date(timeDate); console.log(Time)// (中国标准时间) let timestemp = Time.getTime(); console.log(timestemp) }
