function getDays() {
//构造当前日期对象
var date = new Date(); //获取年份
var year = date.getFullYear(); //获取当前月份
var mouth = date.getMonth() + 1; //定义当月的天数;
var days; //当月份为二月时,根据闰年还是非闰年判断天数
if (mouth == 2) {
days = year % 4 == 0 ? 29 : 28; }
else if (mouth == 1 || mouth == 3 || mouth == 5 || mouth == 7 || mouth == 8 || mouth == 10 || mouth == 12) {
//月份为:1,3,5,7,8,10,12 时,为大月.则天数为31;
days = 31;
}
else {
//其他月份,天数为:30.
days = 30; }
return days;
}
