js筛选最近三天、七天、一个月、三个月、年份的数据
html部分的代码：
'popper_wrapper'
placement="bottom-start"
width="180"
trigger="click"
ref='popover4'
v-model= "popoverShow4">
group v-model="checkTime">
"近七天">
"近一个月">
"近三个月">
'NowYear'>
'LastYear'>
'LastLastYear'>
'threeYearAgo'>
group>
'footer_wrapper'>
'btn quxiao' @click='popoverShow4 = false'>取消
'btn sure' @click='sureSelectTime'>确认
//数据部分

// js部分
// 点击确定后

// 计算开始和结束的时间差

},
// 显示当前时间以及几年前的时间
timeForMat () {
// 拼接时间
let time1 = new Date();
time1.setTime(time1.getTime());
let Y1 = time1.getFullYear();
let M1 = ((time1.getMonth() + 1) > 10 ? (time1.getMonth() + 1) : '0' + (time1.getMonth() + 1));
let D1 = (time1.getDate() > 10 ? time1.getDate() : '0' + time1.getDate());
this.timer1 = Y1 + '-' + M1 + '-' + D1; // 当前时间
// let time2 = new Date()
// time2.setTime(time2.getTime() - (24 * 60 * 60 * 1000 * (count-1)))
// let Y2 = time2.getFullYear()
// let M2 = ((time2.getMonth() + 1) > 10 ? (time2.getMonth() + 1) : '0' + (time2.getMonth() + 1))
// let D2 = (time2.getDate() > 10 ? time2.getDate() : '0' + time2.getDate())
// this.timer2 = Y2 + '-' + M2 + '-' + D2 //七天或30天前的数据
},效果：
