准备阶段的JS

constructor() { this.now = new Date(); this.nowYear = this.now.getYear(); //当前年 this.nowMonth = this.now.getMonth(); //当前月 this.nowDay = this.now.getDate(); //当前日 this.nowDayOfWeek = this.now.getDay(); //今天是本周的第几天 this.nowYear += (this.nowYear < 2000) ? 1900 : 0; } //格式化数字 formatNumber(n) { n = n.toString() return n[1] ? n : '0' + n } //格式化日期 formatDate(date) { let myyear = date.getFullYear(); let mymonth = date.getMonth() + 1; let myweekday = date.getDate(); return [myyear, mymonth, myweekday].map(this.formatNumber).join('-'); } //获取某月的天数 getMonthDays(myMonth) { let monthStartDate = new Date(this.nowYear, myMonth, 1); let monthEndDate = new Date(this.nowYear, myMonth + 1, 1); let days = (monthEndDate - monthStartDate) / (1000 * 60 * 60 * 24); return days; } //获取本季度的开始月份 getQuarterStartMonth() { let startMonth = 0; if (this.nowMonth < 3) { startMonth = 0; } if (2 < this.nowMonth && this.nowMonth < 6) { startMonth = 3; } if (5 < this.nowMonth && this.nowMonth < 9) { startMonth = 6; } if (this.nowMonth > 8) { startMonth = 9; } return startMonth; }

时段函数JS

//获取今天的日期 getNowDate() { return this.formatDate(new Date(this.nowYear, this.nowMonth, this.nowDay)); } //获取本周的开始日期 getWeekStartDate() { return this.formatDate(new Date(this.nowYear, this.nowMonth, this.nowDay - this.nowDayOfWeek + 1)); } //获取本周的结束日期 getWeekEndDate() { return this.formatDate(new Date(this.nowYear, this.nowMonth, this.nowDay + (6 - this.nowDayOfWeek + 1))); } //获取本月的开始日期 getMonthStartDate() { return this.formatDate(new Date(this.nowYear, this.nowMonth, 1)); } //获取本月的结束日期 getMonthEndDate() { return this.formatDate(new Date(this.nowYear, this.nowMonth, this.getMonthDays(this.nowMonth))); } //获取本季度的开始日期 getQuarterStartDate() { return this.formatDate(new Date(this.nowYear, this.getQuarterStartMonth(), 1)); } //获取本季度的结束日期 getQuarterEndDate() { return this.formatDate(new Date(this.nowYear, this.getQuarterStartMonth() + 2, this.getMonthDays(this.getQuarterStartMonth() + 2))); } //获取本年的开始日期 getYearStartDate() { return this.formatDate(new Date(this.nowYear, 0, 1)); } //获取本年的结束日期 getYearEndDate() { return this.formatDate(new Date(this.nowYear, 11, 31)); }

使用方法

1.引入getperiod.js

const GetPeriod = require("../../utils/getperiod.js");

2.使用getperiod.js

this.time = new GetPeriod(); //获取本年的结束日期 let end = this.time.getYearEndDate();
