function getDays() { //構造當前日期對象 var date = new Date(); //獲取年份 var year = date.getFullYear(); //獲取當前月份 var mouth = date.getMonth() + 1; //定義當月的天數; var days; //當月份為二月時,根據閏年還是非閏年判斷天數 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) { //月份為:1,3,5,7,8,10,12 時,為大月.則天數為31; days = 31; } else { //其他月份,天數為:30. days = 30; } return days; }
