整理了一下，这个日历的思路是这样的
- 一个月的总天数
- 一个月中第一天是星期几，即可知道前面空几个
data(){
return {
objmonth:[]
}
}
methods:{
makeCalendar(year,month){
let now = new Date()
let y = now.getFullYear()
let m = now.getMonth()
let d = now.getDate()
let now1 = new Date(y,m,d) //当天时间
let week = now.getDay()
let endDay = new Date(year,month,0)//下个月的第0天，也说是上个月的最后一天，实例化
let lastDay = endDay.getDate() //*这个月总天数
let weekobj = new Date(year,month-1,1) //第一天实例化
let firstWeek = weekobj.getDay() //第1天周几 即可知道前面空几个
for(let i = 1;i<=lastDay;i++){
let now2 = new Date(year,month,i) //每一天都实例化
let _y = _now.getFullYear()
let _m = _now.getMonth()
let _d = _now.getDate()
let _week = _now.getDay()
let objday = {
ymd: `${_y}-${this.transeNum(_m)}-${this.transeNum(_d)}`
day: _d,
week: _week,
isWeekDay: _week==0 || _week==6,
isToday: now1.getTime() == now2.getTime(),
isPass: now1.getTime() > now2.getTime()
}
this.objmonth.push(objday)
}
for(let i = 0;i<firstWeek;i++){
this.objmonth.unshift('') //补齐前面的空格
}
}
transeNum(num){
return num < 10 ? '0' + num :num //小于10的数补0
}
}
mounted() {
this.makeCalendar(2019,4) //调用函数
}
