话不多说，请看代码：
获取今天
var nowDate= new Date(); //当天日期
console.log(nowDate);
//今天是本周的第几天
var nowDayOfWeek= nowDate.getDay();
console.log(nowDayOfWeek);
//当前日
var nowDay = nowDate.getDate();
console.log(nowDay);
//当前月
var nowMonth = nowDate.getMonth();
console.log(nowMonth);
//当前年
var nowYear = nowDate.getFullYear();
console.log(nowYear);
//var nowHours = nowDate.getHours();
//var nowMinutes = nowDate.getMinutes();
//var nowSeconds = nowDate.getSeconds();
nowYear += (nowYear < 2000) ? 1900 : 0; //
console.log(nowYear);
var lastMonthDate = new Date(); //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));
var lastYear = lastMonthDate.getYear();
console.log(lastYear);
var lastMonth = lastMonthDate.getMonth();
console.log(lastMonth);
//格式化日期：yyyy-MM-dd
function formatDate(date) {
var myyear = date.getFullYear();
var mymonth = date.getMonth()+1;
var myweekday = date.getDate();
//var myHours = date.getHours();
//var myMinutes = date.getMinutes();
//var mySeconds = date.getSeconds();
if(mymonth < 10){
mymonth = "0" + mymonth;
}
if(myweekday < 10){
myweekday = "0" + myweekday;
}
//if(myHours < 10){
// myHours = "0" + myHours;
//}
//if(myMinutes < 10){
// myMinutes = "0" + myMinutes;
//}
return (myyear+"/"+mymonth + "/" + myweekday);
//return (myyear+"/"+mymonth + "/" + myweekday + " " + myHours+ ":" + myMinutes);
}
//获得某月的天数
function getMonthDays(myMonth){
var monthStartDate = new Date(nowYear,myMonth,1);
var monthEndDate = new Date(nowYear,myMonth + 1,1);
var days = (monthEndDate - monthStartDate)/(1000 * 60 * 60 * 24);

}
////获得本季度的开始月份
