js获取当天最后一秒和所在星期最后一秒的时间戳

话不多说，直接上代码：

//获取每一天24点前一秒的时间戳

var todayYear=(new Date()).getFullYear();

var todayMonth=(new Date()).getMonth();

var todayDay=(new Date()).getDate();

var todayTime=(new Date(todayYear,todayMonth,todayDay,'23','59','59')).getTime();//毫秒

console.log(todayTime);

//获取当天所在星期最后一天24点前一秒的时间戳，假设最后一天为星期天

var todayYear=(new Date()).getFullYear();

var todayMonth=(new Date()).getMonth();

var todayDay=(new Date()).getDate();

var day=(new Date()).getDay()==0?7:(new Date()).getDay();

//0为星期天,如果星期六为最后一天，则var day=(new Date()).getDay();，下行代码7改为6

todayDay = todayDay+(7-day);

var todayTime=(new Date(todayYear,todayMonth,todayDay,'23','59','59')).getTime();//毫秒

console.log(todayTime);
