指定从 1970-1-1 00:00:00 UTC 开始经过的毫秒数来设置日期对象的时间
val 表示一个整数, (毫秒数)
var date = new Date(); var yesterday_milliseconds = date.getTime() - 1000 * 60 * 60 * 24; var yesterday = new Date(); yesterday.setTime(yesterday_milliseconds); console.log(yesterday); var yesyear = yesterday.getFullYear(); var yesmonth = yesterday.getMonth(); var yesDay = yesterday.getDate(); var finalyes = new Date(yesyear, yesmonth, yesDay);
Date.prototype.setTime( val )
