JavaScript 时间与时间戳转换

一、获取当前时间戳

var timestamp = new Date().getTime();console.log(timestamp);

二、yyyy-MM-dd hh:mm:ss 格式的当前时间

function getdate() {
    var now = new Date();
    var   Y = now.getFullYear();
    var   M = now.getMonth() + 1;
    var   D = now.getDate();
    var   m = M < 10 ? "0" + M : M;
    var   d = D < 10 ? "0" + D : D;
    return Y + "-" + m + "-" + d + " " + now.toTimeString().substr(0, 8);
 }

三、时间转为时间戳

 function gettime(dateTime) {
    var time = Date.parse(new Date(dateTime));
    return time;
 }

var stringTime = ‘2017/06/13 10:22:00‘;
  console.log(stringTime + "的时间戳为：" + gettime(stringTime))
