//获取今天
var nowDate= new Date(); //当天日期

//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;
