デフォルト時間の取得

 export function getSingleDate() {
 return new Promise((resolve, reject) => {
 let nowTime = new Date();
 let year = nowTime.getFullYear();
 let month = nowTime.getMonth() + 1;
 let nowDay = nowTime.getDate();

 let dates = year + '-' + month + '-' + nowDay;
 
 if (dates) {
 resolve({
 date: dates,
 })
 } else {
 reject({
 date: ,
 })
 }
 })
 }

日付形式の変換

Date.prototype.format= function(format) {
 var o = {
 "M+" : this.getMonth()+1, //month
 "d+" : this.getDate(), //day
 "h+" : this.getHours(), //hour
 "m+" : this.getMinutes(), //minute
 "s+" : this.getSeconds(), //second
 "q+" : Math.floor((this.getMonth()+3)/3), //quarter
 "S" : this.getMilliseconds() //millisecond
 }
 if(/(y+)/.test(format)) format=format.replace(RegExp.$1,
 (this.getFullYear()+"").substr(4 - RegExp.$1.length));
 for(var k in o)if(new RegExp("("+ k +")").test(format))
 format = format.replace(RegExp.$1,
 RegExp.$1.length==1 ? o[k] :
 ("00"+ o[k]).substr((""+ o[k]).length));
 return format;
};

当月の翌月時間取得

 export function getNextTime() {
 return new Promise((resolve, reject) => {
 let nowTime = new Date();
 let year = nowTime.getFullYear();
 let month = nowTime.getMonth() + 2 > 12 ? 1 : nowTime.getMonth() + 2;
 let date1 = new Date(year, month-1, 1).format('yyyy-MM-dd');
 let date2 = new Date(year, month, 0).format('yyyy-MM-dd');
 if (date1 && date2) {
 resolve({
 start: date1,
 end: date2
 })
 } else {
 reject({
 start: '',
 end: ''
 })
 }
 })
}

当月の翌月を取得

 export function getNextMonth() {
 return new Promise((resolve, reject) => {
 let nowTime = new Date();
 let year = nowTime.getFullYear();
 let month = nowTime.getMonth() + 2 > 12 ? 1 : nowTime.getMonth() + 2;
 let date1 = new Date(year, month-1, 1).format('MM-dd');
 let date2 = new Date(year, month, 0).format('MM-dd');
 
 
 if (date1 && date2) {
 resolve({
 start: date1,
 end: date2
 })
 } else {
 reject({
 start: '10-17',
 end: '10-17'
 })
 }
 })
 }

デフォルトの月を取得

export function getDefaultMonth() {
return new Promise((resolve, reject) => {
 let nowTime = new Date();
 let year = nowTime.getFullYear();
 let month = nowTime.getMonth() + 1;
 let currentMonth = year + '-' + month;
 if(currentMonth){
 resolve({
 month: currentMonth
 })
 }else {
 reject({
 month: ''
 })
 }
})

}

日数を計算

export function getDays() {
 let s1 = '';
 let s2 = '';
 s1 = new Date(s1.replace(/-/g, "/"));
 s2 = new Date(s2.replace(/-/g, "/"));
 let days = s2.getTime() - s1.getTime();
 let time = parseInt(days / ( * 24));
}

指定時間の取得

• params

• type: type default aftertime ;val 日付からNヶ月後

   export function getAppointDate(val, num = 3, type = 'aftertime') {
   let backVal;
   switch (type) {
   case 'aftertime':
   let month = val.match(/-\d{1,2}/)[0];
   let inx = val.search(/-\d{1,2}/);
   month *= -1;
   let totalMonth = month + num;
   let addYear = Math.floor((month + num) / 12);
   let intCountDate = totalMonth % 12 || totalMonth;
   let countDate = totalMonth <= 12 ? `${val.substring(0, inx)}-${intCountDate}` : `${val.substring(0, inx) * 1 + addYear}-${intCountDate}`;
   let is31Day = [1, 3, 5, 7, 8, 10, 12];
   let is30Day = [4, 6, 9, 11];
   let day = val.match(/-\d{1,2}$/)[0] * - 1;
   if (is31Day.indexOf(intCountDate) > -1) {
   day = day > 31 ? 31 : day;
   } else if (is30Day.indexOf(intCountDate) > -1) {
   day = day > 30 ? 30 : day;
   } else {
   if (val.substring(0, 3) % 4 === 0) {
   day = day > 29 ? 29 : day;
   } else {
   day = day > 28 ? 28 : day;
   }
   }
   backVal = countDate + '-' + day;
   break;
   }
   return backVal;
   }
