基于element ui的Calendar实现添加自定义内容

目标

实现的内容是在Element UI的 Calenda 中可以自己添加内容

官方文档

通过设置名为 dateCell 的 scoped-slot 来自定义日历单元格中显示的内容。在 scoped-slot 可以获取到 date（当前单元格的日期）, data（包括 type，isSelected，day 属性）。

自定义要改的内容

直接看下面code

1. value的值是选中月份的值
2. calendarData中的每一对象的dutyDate的格式是2021-01-20
3. 主要方法handleAddClick，handleEventClick
4. 用户信息格式：

 {
            "id": 14,
            "loginName": "nige",
            "userName": "倪割",
            "ding_user_id": "23123123"
        },

以下为完整代码：

创建axios实例

import axios from "axios";

// For common config
axios.defaults.headers.post["Content-Type"] = "application/json";

const mainAxios = axios.create({
  baseURL: 'https://dingtalk.nige.com',
  timeout: 30000
});

export function fetch(url, config = {}) {
  return new Promise((resolve, reject) => {
    mainAxios.get(url, { params: config })
      .then(response => {
        resolve(response.data)
      })
      .catch(err => {
        reject(err)
      })
  })
}

统一改变后端返回的java Long类型

当后端的Long类型返回超过前端JS能处理的长度时，那么可以在前端统一处理成String.

1. 安装json-bigint
2. 在的JS文件中使用var jsonBig = require(‘json-bigint’)
3. 在请求的方法中使用：

export function post(url, data = {}, config = { transformResponse: [data => jsonBig.parse(data)] }) {
  // export function post(url, data = {}, config = {}) {
  return new Promise((resolve, reject) => {
    axios.post(url, data, config)
      .then(response => {
        resolve(response.data)
      }, err => {
        reject(err)
      })
  })
}
