當月第一天,和當月最后一天的獲取方式...這個就確實比較扯了,但事實上它就要這樣....

1.如何計算出現位置
wrapper.left=input.offsetleft
wrapper.top=input.top+height
2.ui設計 div+table
3.一個月有4-6個星期
4.當月第一天 new Date（year，month-1，1）
當月最后天 new Date（year，month，0）因為月可能28天可能30，31
星期1-星期天【1,2,3,4,5,6】
5.組件結構

vscode數字范圍插件

第一天

new Date(year, minth-1, 1)

最后一天

new Date(year, month,0)

(function?()?{
???var?datepicker?=?{};
????datepicker.getMonthData?=?function?(year,month)?{
????????var?ret?=?[];
????????if(!year?||?!month){
????????????var?today?=?new?Date();
????????????year?=?today.getFullYear();
????????????month?=?today.getMonth()+1;
????????}
????????var?firstDay?=?new?Date(year,month-1,1);
????????var?firstDayWeekDay?=?firstDay.getDay();
????????if(firstDayWeekDay?===?0)
????????????firstDayWeekDay?=?7;

????????var?lastDayOfLastMonth?=?new?Date(year,month-1,0);
????????var?lastDateOfLastMonth?=?lastDayOfLastMonth.getDate();

????????var?preMonthDayCount?=?firstDayWeekDay?-1;

????????var?lastDay?=?new?Date(year,month,0);
????????var?lastDate?=?lastDay.getDate();

????????//利用循環查詢到一周日期
????????for(?var?i?=?0;?i<7*6;?i++){
????????????var?date?=?i+1?-?preMonthDayCount;
????????????var?showDate?=?date;
????????????var?thisMonth?=?month;
????????????if(date?<=?0){
????????????????thisMonth?=?month?+1;
????????????????showDate?=?lastDateOfLastMonth?+date;
????????????}else?if(date?>?lastDate){
????????????????thisMonth?=?month?+1;
????????????????showDate?=?showDate-lastDate;
????????????}if(thisMonth?===?0)thisMonth?=?12;
????????????if(thisMonth?===?13)?thisMonth?=?1;

????????????ret.push({
???????????????month:thisMonth,
???????????????date:date,
????????????????showDate:showDate
????????????});
????????}
????????return?ret;
????};
???window.datepicker?=?datepicker;

})();

new Date(year, month-1, date)

月份需要減一

越界自動退位

getFullYear()/ getMonth()/ ?getDate() ? / ?getDay() [獲取星期0到6]

當月第一天new Date(year, minth-1, 1)

當月最后一天new Date(year, month,0)
