使用javascript向datetime添加秒

Question

如何在Javascript中以以下格式添加秒到日期?

x = '2015-05-23 11:20:33';
setInterval(function () {
  console.log(x+1);  //Looking something in this place to add a second and show in the same format
}, 1000); 

Answer 1

使用setSeconds()

var date = new Date('2015-05-23 11:20:33');
setInterval(function () {
  date.setSeconds(date.getSeconds() + 1);
  console.log(
    date.getFullYear()+'-'+
    (date.getMonth()+1)+'-'+
    date.getDate()+' '+
    date.getHours()+':'+
    date.getMinutes()+':'+
    date.getSeconds()
    );//to ensure log is  'YYYY-MM-DD HH:MM:SS' format
}, 1000);
