【vue自定义组件】实现一个污染日历

前言


佛祖保佑, 永无bug。Hello 大家好!我是海的对岸!


实际开发中,碰到一个日历的需求,这个日历的需求中要加入定制的业务,网上没有现成的,手动实现了一下,整理记录下。

实现


实现背景


工作上碰到一个需求,需要有一个可以在日历上能看到每天的污染情况的状态,因此,我们梳理下需求:



  1. 要有一个日历组件
  2. 要在这个日历组件中追加自己的业务逻辑

简单拎一下核心代码的功能


实现日历模块


大体上日历就是看某个月有多少多少天,拆分下,如下所示:

再对比这我们的效果图,日历上还要有上个月的末尾几天

实现上个月的末尾几天


monthFisrtDay() {
// 所指的星期中的某一天,使用本地时间。返回值是 0(周日) 到 6(周六) 之间的一个整数
// eslint-disable-next-line radix
const currDT = (parseInt(this.year.substr(0, 4)) + '/' + parseInt((this.month).replace('月', '')) + '/1');
let currWeek = new Date(currDT).getDay();
return ++currWeek || 7;
},
// 刷新日历 获得上个月的结尾天数 <=7
refreshCalendar() {
this.nunDays = [];
const lastDays = [];
const lastMon = (this.month).replace('月', '') * 1 - 1;
let lastDay = new Date(new Date(this.year.substr(0, 4), lastMon).getTime() - 8.64e7).getDate();
for (let i = 1; i < this.monthFisrtDay(); i += 1) {
lastDays.unshift(lastDay);
lastDay -= 1;
}
this.nunDays = lastDays;
},

实现每个月的实际天数


// 展示 日历数据
getDatas() {
if (this.dealDataFinal && this.dealDataFinal.length > 0) {
// console.log(this.dealDataFinal);
this.list = [];
const datas = this.dealDataFinal;
const dataMap = {};
if (datas.length > 0) {
datas.forEach((item) => {
item.level -= 1;
item.dateStr = item.tstamp.substr(0, 10);
item.date = item.tstamp.substr(8, 2);
dataMap[item.date] = item;
});
}

const curDay = new Date().getDate();
for (let i = 1; i <= this.monthDays; i += 1) {
let currColor = this.lvls[6];
let dateStr = String(i);
let isCurDay = false;
if (i == curDay) {
isCurDay = true; // 表示刚好是今天(该日期 和网络上的今天是同一天)
}
dateStr = '0' + dateStr;
dateStr = dateStr.substr(dateStr.length - 2);
const dataObj = dataMap[dateStr];
if (dataObj) {
if (dataObj.level >= 0 && dataObj.level <= 5) {
currColor = this.lvls[dataObj.level].color;
} else {
currColor = this.lvls[6].color;
}

this.list.push({
date: i,
curDay: isCurDay,
color: currColor,
datas: dataObj,
checkedColor: undefined, // 选中颜色
});
} else {
this.list.push({
date: i,
curDay: isCurDay,
color: this.lvls[6].color,
datas: {},
checkedColor: undefined, // 选中颜色
});
}
}
// console.log(this.list);
} else {
this.clearCalendar();
}
},
// 清除上一次的记录
clearCalendar() {
this.list = [];
for (let i = 1; i <= this.monthDays; i += 1) {
this.list.push({
date: i,
color: this.lvls[6].color,
datas: {},
});
}
},

实现日历之后,追加业务


定义业务上的字段


data() {
return {
...
lvls: [
{ title: '优', color: '#00e400' },
{ title: '良', color: '#ffff00' },
{ title: '轻度污染', color: '#ff7e00' },
{ title: '中度污染', color: '#ff0000' },
{ title: '重度污染', color: '#99004c' },
{ title: '严重污染', color: '#7e0023' },
{ title: '未知等级', color: '#cacaca' },
],
list: [], // 当前月的所有天数
dealDataFinal: [], // 处理接口数据之后获得的最终的数组
...
curYearMonth: '', // 当前时间 年月
choseYearMonth: '', // 选择的时间 年月
};
},

定义业务上的方法


// 加载等级
loadImgType(value) {
let imgUrl = 0;
switch (value) {
case '优':
imgUrl = 1;
break;
case '良':
imgUrl = 2;
break;
case '轻':
imgUrl = 3;
break;
case '中':
imgUrl = 4;
break;
case '重':
imgUrl = 5;
break;
case '严':
imgUrl = 6;
break;
default:
imgUrl = 0;
break;
}
return imgUrl;
},

因为展示效果,用到的是css,css用的比较多,这里就不一段一段的解读了,总而言之,就是日元素不同状态的样式展示,通过前面设置的等级方法,来得到不同的返回参数,进而展示出不同参数对应的不同颜色样式。


最后会放出日历组件的完整代码。
