var fmt = ‘YYYY-MM-DD HH:mm‘;
var now = new Date();
var end = new Date();
if(v == 0){
} else if(v == 1){
} else if(v == 2){
//昨日
now.setDate(now.getDate() - 1);
end.setDate(end.getDate() - 1);
} else if(v == 3){
//本周
var nowDayOfWeek = now.getDay() ; //今天本周的第几天
if(nowDayOfWeek == 0) {
nowDayOfWeek = 6; //周日
} else {
nowDayOfWeek = nowDayOfWeek - 1;
}
now.setDate(now.getDate() - nowDayOfWeek);
end.setDate(now.getDate() + 6);
} else if(v == 4){
//上周
var nowDayOfWeek = now.getDay() ; //今天本周的第几天
if(nowDayOfWeek == 0) {
nowDayOfWeek = 6; //周日
} else {
nowDayOfWeek = nowDayOfWeek - 1;
}
now.setDate(now.getDate() - nowDayOfWeek - 7);
end.setDate(now.getDate() + 6);
} else if(v == 5){
//本月
now.setDate(1);
var nextMonth = end.getMonth() + 1;
var nextMonthFirstDay=new Date(end.getFullYear(), nextMonth,1);
var oneDay= 1000 * 60 * 60 * 24;
end = new Date(nextMonthFirstDay-oneDay);
} else if(v == 6){
//上月
var nextMonth = now.getMonth() - 1;
now.setMonth(nextMonth);
now.setDate(1);
