1、传入参数
1.1、顶部背景图片
文章图片
如上图红圈区域的照片背景设置
在组件参数中定义
bgSrc: {
type: String,
default: 'https://images8.alphacoders.com/992/992329.jpg'
}1.2、日历标题
文章图片
如上图圈住区域文字设置
在组件参数中定义
title: {
type: String,
default: '日历'
}2、回调方法
2.1、选中日期 使用this.$ emit()向父组件传递数据。
在组件日期点击事件中执行。
clickDay (day) {
this.selectDay = day
this.$emit('selectDay', day)
}2.2、切换月份 使用this.$ emit()向父组件传递数据。
在组件日期点击事件中执行。
//上个月
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.$emit('changeMonth', year + '-' + this.zero(month))
},
//下个月
toNextMonth () {
let year = this.selectMonth.split('-')[0]
let month = this.selectMonth.split('-')[1]
month = parseInt(month) + 1
if (month === 13) {
month = 1
year = parseInt(year) + 1
}
this.days = this.fillDays(year, month)
this.$emit('changeMonth', year + '-' + this.zero(month))
}3、组件js模块开发流程
3.1、月份天数确认 3.1.1、判断润年
/**
* 判断润年
* @param {string} year 需要判断的年份
* @return {Boolean}
*/
function isLeap(year) {
if((year%4==0 && year%100!=0)||(year%400==0)){
return true;
}
return false;
}3.1.2、获取月份天数
/**
* 获取月份天数
* @param {string} year年份
* @param {string} month 月份
* @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、获取星期
/**
* 获取星期
* @param {string} date 需要获取星期的日期
* @return {string}
*/
function getWeek(date){
let weeks = new Array("日","一","二","三","四","五","六");
let Stamp = new Date(date);
console.log(weeks[Stamp.getDay()])
}3.1.4、补充满天数
/**
* 补零
* @param {string} str 需要补零的数
* @return {string}
*/
function zero(str){
return str > 9 ? str : '0' + str;
}
/**
* 补充满天数
* @param {string} year年份
* @param {string} month 月份
* @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、点击事件 3.2.1、月份切换
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、日期点击
clickDay (day) {
this.selectDay = day
this.$emit('selectDay', day)
}4、html模块
{{title}}<
{{selectMonth}}
>回到今天周{{item}}{{item.split('-')[2]}}5、CSS样式
@media screen and (max-width:500px) {
.header{
height: calc(100vw * 9 / 16);
}
}
.header{
display: flex;
flex-direction: column;
.header-title{
line-height: 5rem;
}
.btn-list{
display: flex;
padding: 1rem;
margin-top: auto;
.btn-list-left{
padding: 0.5rem;
width: 40%;
display: flex;
.select-month{
flex: 2;
}
.btn-pre{
flex: 1;
background-color: #0080FF;
}
.btn-next{

background-color: #0080FF;
}
}
.btn-today{
padding: 0.5rem;
margin-left: auto;
margin-right: 1rem;
background-color: #076678;
color: white;
}
}
}
.calendar-content{
display: flex;
flex-wrap: wrap;
width: 100%;
.selected{
background-color: #007FAA;
}
.grid{
width: calc((100% - 9px)/7);
height: 3rem;
line-height: 3rem;
border-left: #005599 solid 1px;
border-bottom: #005599 solid 1px;
}
.grid-week{
border-top: #005599 solid 1px;
}
.grid-week:nth-child(7){
border-right: #005599 solid 1px;
}
.grid-day:nth-child(14){
border-right: #005599 solid 1px;
}
.grid-day:nth-child(21){
border-right: #005599 solid 1px;
}
.grid-day:nth-child(28){
border-right: #005599 solid 1px;
}
.grid-day:nth-child(35){
border-right: #005599 solid 1px;
}
.grid-day:nth-child(42){
border-right: #005599 solid 1px;
