js时间函数

//获取今天的日期和时间var myDate = new Date();

var year = myDate.getFullYear(); //年var month = myDate.getMonth() + 1;//月var date = myDate.getDate();//日var h = myDate.getHours(); //当前时(0-23)var m = myDate.getMinutes(); //当前分(0-59)var s = myDate.getSeconds();//当前秒(0-59)

//获取明天的日期

   var tomorrow = new Date();

tomorrow.setTime(tomorrow.getTime() + 24*60*60*1000);

tomorrow_month = tomorrow.getMonth()+1;//月

 tomorrow_date =  tomorrow.getDate();//日

//获取当前时间戳

var now_timestamp = myDate.getTime();

//获取指定时间的时间戳

var time = new Date( year, myDate.getMonth(), date, h, m, s);var timestamp = time.getTime()

//比较两个时间的大小（先后）if(now_timestamp > timestamp){    alert(‘当前时间大‘);}
