Question

我从当前日期减去时间时遇到问题。我的代码看起来像：

var d = new Date(),
year = d.getUTCFullYear(),
month = ('0'+(d.getUTCMonth()+1)).slice(-2),
day = ('0'+d.getUTCDate()).slice(-2),
hour = ('0'+d.getUTCHours()).slice(-2),
minute = ('0'+d.getUTCMinutes()).slice(-2),
second = ('0'+d.getUTCSeconds()).slice(-2);

var startDate = year+'/'+month+'/'+day+'-'+hour+':'+minute+':'+second;
console.log(startDate);

Answer 1

获取日期变量的毫秒数，减去5分钟并从中创建一个新的日期对象：

var d = new Date()
// d = Mon Feb 29 2016 08:00:09 GMT+0100 (W. Europe Standard Time)
var milliseconds = Date.parse(d)
// 1456729209000
milliseconds = milliseconds - (5 * 60 * 1000)
// - 5 minutes
d = new Date(milliseconds)
// d = Mon Feb 29 2016 07:55:04 GMT+0100 (W. Europe Standard Time)

Answer 2

如果您准备使用称为时刻js的新日期操作js。

您只需在以下一个功能中执行此操作：

moment().subtract(5, 'minutes');

Answer 3

你可以简单地通过

减去

minute = ('0'+d.getUTCMinutes()).slice(-2)-5

var d = new Date(),
    year = d.getUTCFullYear(),
    month = ('0'+(d.getUTCMonth()+1)).slice(-2),
    day = ('0'+d.getUTCDate()).slice(-2),
    hour = ('0'+d.getUTCHours()).slice(-2),
    minute = ('0'+d.getUTCMinutes()).slice(-2),
    second = ('0'+d.getUTCSeconds()).slice(-2);

    if (minute>=5)
      minute = minute-5;
    else {
      minute = (parseInt(minute) + 60) - 5;
      hour = hour - 1;
    }

    var startDate = year+'/'+month+'/'+day+'-'+hour+':'+minute+':'+second;
    alert(startDate);

Answer 4

你可以这样使用

＆＃13;

var original = new Date();
var subtract5min = new Date();
alert("before : " + original);
subtract5min.setTime(original.getTime() - 5*60*1000);
alert("after : " + subtract5min);

Answer 5

您可以像下面这样简单地使用

var fiveMinuteAgo = new Date( Date.now() - 1000 * (60 * 5) )

从当前日期和时间javascript减去5分钟
