Defined in component parameters
title: {
type: String,
Default: 'calendar'
}
2. Callback method
2.1. Selected date
Use this. & dollar; Emit() passes data to the parent component.
Execute in the component date click event.
clickDay (day) {
this.selectDay = day
this.$emit('selectDay', day)
}
2.2 switching month
Use this. & dollar; Emit() passes data to the parent component.
Execute in the component date click event.
//Last month
toPreMonth () {
let year = this.selectMonth.split('-')[0]
let month = this.selectMonth.split('-')[1]
month = parseInt(month) - 1
if (month === 0) {
month = 12
year = parseInt(year) - 1
}
this.days = this.fillDays(year, month)
this.$emit('changeMonth', year + '-' + this.zero(month))
},
//Next month
toNextMonth () {
let year = this.selectMonth.split('-')[0]
let month = this.selectMonth.split('-')[1]
month = parseInt(month) + 1
if (month === 13) {
month = 1
year = parseInt(year) + 1
}
this.days = this.fillDays(year, month)
this.$emit('changeMonth', year + '-' + this.zero(month))
}
3. Component JS module development process
3.1 confirmation of months and days
3.1.1. Judge the profit year
/**
*Judge Runnian
*@ param {string} year year to judge
* @return {Boolean}
*/
function isLeap(year) {
if((year%4==0 && year%100!=0)||(year%400==0)){
return true;
}
return false;
}
3.1.2. Obtain month and days
/**
*Get month days
*@ param {string} year
*@ param {string} month
* @return {string}
*/
function getMonthDays(year,month) {
month = parseInt(month) - 1;
if(month < 0 || month > 11) return ''
let months = [31,28,31,30,31,30,31,31,30,31,30,31];
if(isLeap(year)){
months[1] = 29;
}
return months[month];
}
3.1.3 get week
/**
*Get week
*@ param {string} date needs to get the date of the week
* @return {string}
*/
function getWeek(date){
Let weeks = new array ("day", "one", "two", "three", "four", "Five", "six");
let Stamp = new Date(date);
console.log(weeks[Stamp.getDay()])
}
3.1.4 replenishment of full days
/**
*Zero filling
*@ param {string} STR the number of zeros to be filled
* @return {string}
*/
function zero(str){
return str > 9 ? str : '0' + str;
}
/**
*Supplementary full days
*@ param {string} year
*@ param {string} month
* @return {string}
*/
function fillDays(year,month) {
const months = getMonthDays(year,month);
const startWeek = getWeek(year + '-' + month + '-' + '01');
const endWeek = getWeek(year + '-' + month + '-' + months);
year = parseInt(year);
month = parseInt(month);
let preYear = year;
let preMonth = month - 1;
if(preMonth == 0){
preMonth = 12;
preYear = year - 1;
}
const preMonths = getMonthDays(preYear,preMonth);
let nextYear = year;
let nextMonth = month + 1;
if(nextMonth == 13){
nextMonth = 1;
nextYear = year + 1;
}
const nextMonths = getMonthDays(nextYear,nextMonth);
let days = [];
for(let i = 0; i < startWeek; i++){
days.unshift(preYear + '-' + preMonth + '-' + (preMonths - i));
}
for(let i = 1; i <= months; i++){
days.push(year + '-' + zero(month) + '-' + zero(i));
}
for(let i = 0; i < (6 - endWeek); i++){
days.push(nextYear + '-' + nextMonth + '-0' + (i + 1));
}
return days;
}
3.2 click event
3.2.1 month switching
toPreMonth () {
let year = this.selectMonth.split('-')[0]
let month = this.selectMonth.split('-')[1]
month = parseInt(month) - 1
if (month === 0) {
month = 12
year = parseInt(year) - 1
}
this.days = this.fillDays(year, month)
this.$emit('changeMonth', year + '-' + this.zero(month))
},
toNextMonth () {
let year = this.selectMonth.split('-')[0]
let month = this.selectMonth.split('-')[1]
month = parseInt(month) + 1
if (month === 13) {
month = 1
year = parseInt(year) + 1
}
this.days = this.fillDays(year, month)
this.$emit('changeMonth', year + '-' + this.zero(month))
}
3.2.2 click date
clickDay (day) {
this.selectDay = day
this.$emit('selectDay', day)
}
4. HTML module
<template>
<div>
<div id="header" class="header">
<div class="header-title">{{title}}</div>
<div class="btn-list">
<div class="btn-list-left">
<div class="btn-pre" @click="toPreMonth()"><</div>

<div class="btn-next" @click="toNextMonth()">></div>
</div>
< div class = "BTN today" @ Click = "tonowday()" > back to today < / div >
</div>
</div>
<div class="content" id="content">
<div class="calendar-content">
<div class="grid-week grid" v-for="(item,index) in weeks" :key="index">
Week {{item}}
</div>
<div @click="clickDay(item)"
