获取今天，昨天，本周，上周，本月，上月时间（实例分享）
话不多说，请看代码：
//获取今天
varnowDate=newDate();//当天日期
console.log(nowDate);
//今天是本周的第几天
varnowDayOfWeek=nowDate.getDay();
console.log(nowDayOfWeek);
//当前日
varnowDay=nowDate.getDate();
console.log(nowDay);
//当前月
varnowMonth=nowDate.getMonth();
console.log(nowMonth);
//当前年
varnowYear=nowDate.getFullYear();
console.log(nowYear);
//varnowHours=nowDate.getHours();
//varnowMinutes=nowDate.getMinutes();
//varnowSeconds=nowDate.getSeconds();
nowYear+=(nowYear<2000)?1900:0;//
console.log(nowYear);
varlastMonthDate=newDate();//上月日期
console.log(lastMonthDate);
lastMonthDate.setDate(1);
console.log(lastMonthDate.setDate(1));
lastMonthDate.setMonth(lastMonthDate.getMonth()-1);
console.log(lastMonthDate.setMonth(lastMonthDate.getMonth()-1));
varlastYear=lastMonthDate.getYear();
console.log(lastYear);
varlastMonth=lastMonthDate.getMonth();
console.log(lastMonth);
//格式化日期：yyyy-MM-dd
functionformatDate(date){
varmyyear=date.getFullYear();
varmymonth=date.getMonth()+1;
varmyweekday=date.getDate();
//varmyHours=date.getHours();
//varmyMinutes=date.getMinutes();

mymonth="0"+mymonth;
}

}
//if(myHours<10){

//}
return(myyear+"/"+mymonth+"/"+myweekday);
//return(myyear+"/"+mymonth+"/"+myweekday+""+myHours+":"+myMinutes);
}
//获得某月的天数
functiongetMonthDays(myMonth){
varmonthStartDate=newDate(nowYear,myMonth,1);
varmonthEndDate=newDate(nowYear,myMonth+1,1);
vardays=(monthEndDate-monthStartDate)/(1000*60*60*24);
