Js 获取当前月的天数
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; }
