1、传入参数

1.1、顶部背景图片

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

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

5、CSS样式
