// 设置初始数据

 / 渲染日期

export const getDateStr = (AddDayCount, dateStr, type) => {

  this.selectedMonth = 0

 } else {
  this.selectedMonth = this.selectedMonth + 1
  this.selectedDate = 1
 }
 },


vuex存储数据




// src/store/schedule.js
const schedule = {
 state: {
 selectedDate: '', // 手动点击选中的日期
 currentDate: '' // 服务器当前日期
 },

 getters: {
 getSelectedDate: state => state.selectedDate,
 getCurrentDate: state => state.currentDate
 },

 mutations: {
 SET_SELECTED_DATE: (state, data) => {
 state.selectedDate = data
 },
 SET_CURRENT_DATE: (state, data) => {
 state.currentDate = data
 }
 },

 actions: {
 setSelectedDate: ({ commit }, data) => commit('SET_SELECTED_DATE', data),
 setCurrentDate: ({ commit }, data) => commit('SET_CURRENT_DATE', data)
 }
};

export default schedule;


clickOutSide指令 指令方法监听





// src/directive/click-out-side.js
export default{
 bind (el, binding, vnode) {
 function documentHandler (e) {
 if (el.contains(e.target)) {
 return false;
 }
 if (binding.expression) {
 binding.value(e);
 }
 }
 el.__vueClickOutside__ = documentHandler;
 document.addEventListener('click', documentHandler);
 },
 unbind (el, binding) {
 document.removeEventListener('click', el.__vueClickOutside__);
 delete el.__vueClickOutside__;
 }
}


注册指令



// src/directive/index.js
import clickOutSide from './click-out-side'

const install = function (Vue) {
 Vue.directive('click-outside', clickOutSide)
}

if (window.Vue) {
 window.clickOutSide = clickOutSide
 Vue.use(install); // eslint-disable-line
}

clickOutSide.install = install
export default clickOutSide




// src/main.js
import clickOutSide from '@/directive/click-out-side/index'

Vue.use(clickOutSide)


使用方式：当某节点外部需要触发事件时，挂载到该节点上


// calendar.vue
<div class="cp-calendar" v-click-outside="spaceClick">
....
</div>


这里需要使用 fastclick 库来消除解决移动端点击事件300ms延时


// src/mian.js
import FastClick from 'fastclick' // 在移动端，手指点击一个元素，会经过：touchstart --> touchmove -> touchend --> click。

FastClick.attach(document.body);


mock数据




// src/mock/index.js
// mock数据入口
import Mock from 'mockjs'
import currentTime from './currentTime'

// 拦截接口请求
Mock.mock(/\/schedule\/getCurrentTime/, 'get', currentTime)

export default Mock
// src/mock/currentTime.js
import Mock from 'mockjs'

export default {
 getList: () => {
 return {
 'status': 'true',
 'code': '200',
 'msg': null,
 'info': {
 'currentDate': '2018-09-02'
 }
 }
 }
}
// src/main.js
// 开发环境引入mock
if (process.env.NODE_ENV === 'development') {
 require('./mock') // 需要在这里引入mock数据才可以全局拦截请求
}


坑点

  
在微信内置浏览器中，ios的日期格式跟安卓的日期格式分别是：YY/MM/DD和YY-MM-DD。这里需要对微信内置浏览器User Agent进行判断。
  
获取服务器时间的异步问题，把获取到的服务器时间保存在vuex里面，在calendar.vue页面监听当前日期的变化。及时将日历数据计算渲染出来。
