javascript - 从当前日期和时间javascript减去5分钟

Question

我在从当前日期减去时间时遇到问题。我的代码如下所示:

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

你可以像下面这样简单地使用

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