momentjs是一个处理时间的js库,简洁易用,本文来介绍一下momentjs实现DatePicker时间禁用,具有一定的参考价值,感兴趣的可以了解一下

momentjs是一个处理时间的js库，简洁易用。

浅析一下， momentjs 在vue中对DatePicker时间组件的禁用实践。

一，npm下载

npm install moment --save

二，particles.json中

"dependencies": {
    "axios": "^0.18.0",
    "iview": "^3.4.0",
    "moment": "^2.24.0",
    "vue": "^2.5.10",
    "vue-i18n": "^7.8.0",
    "vue-router": "^3.0.1",
    "vuex": "^3.0.1"
  },

三，引入使用

1.main.js中引入

import 'moment/locale/zh-cn'
moment.locale('zh-cn');  
Vue.prototype.$moment = moment;

2.页面或组件引入使用

import moment from "moment"

3.方法使用

moment().format('YYYY-MM-DD');  //获取格式

moment().startOf('month')  //获取当月第一天
moment().endOf('month')  //获取当月最后一天

moment().subtract(7, 'days')  //获取前7天
moment().subtract(4,'month')  //获取前4个月

更多方法参考momentjs官网：momentjs

4.应用实例

a,日期禁用

 pickerStart: {
        disabledDate(time) {
            let startDate;
            let endDate=moment().subtract(4, "days").format("YYYY-MM-DD");
            if(today<4){
              startDate=moment().subtract(5,'month').endOf('month').format('YYYY-MM-DD');
            }
            if(today>4||today==4){
              startDate=moment().subtract(4,'month').endOf('month').format('YYYY-MM-DD');
            }
            return (
              time && time.valueOf() < new Date(startDate).getTime() ||
              time.valueOf() > new Date(endDate).getTime()
            );
        }
      },
      pickerEnd: {
        disabledDate(time) {
            let startDate;
            let endDate=moment().subtract(4, "days").format("YYYY-MM-DD");
            if(today<4){
              startDate=moment().subtract(5,'month').endOf('month').format('YYYY-MM-DD');
            }
            if(today>4||today==4){
              startDate=moment().subtract(4,'month').endOf('month').format('YYYY-MM-DD');
            }
            return (
              time && time.valueOf() < new Date(startDate).getTime() ||
              time.valueOf() > new Date(endDate).getTime()
            );
        },
      },

b,月份禁用

     pickerStart: {
        disabledDate(time) {
            let startMonth;
            let endMonth;
            if(today<4){
              startMonth=moment().subtract(5, "month").format("YYYY-MM");
              endMonth=moment().subtract(2, "month").format("YYYY-MM");
            }
            if(today>4||today==4){
              startMonth=moment().subtract(4, "month").format("YYYY-MM");
              endMonth=moment().subtract(1, "month").format("YYYY-MM");
            }
            return (
              time && time.valueOf() < new Date(startMonth).getTime() ||
              time.valueOf() > new Date(endMonth).getTime()
            );
        }
      },
      pickerEnd: {
        disabledDate(time) {
            let startMonth;
            let endMonth;
            if(today<4){
              startMonth=moment().subtract(5, "month").format("YYYY-MM");
              endMonth=moment().subtract(2, "month").format("YYYY-MM");
            }
            if(today>4||today==4){
              startMonth=moment().subtract(4, "month").format("YYYY-MM");
              endMonth=moment().subtract(1, "month").format("YYYY-MM");
            }
            return (
              time && time.valueOf() < new Date(startMonth).getTime() ||
              time.valueOf() > new Date(endMonth).getTime()
            );
        },
      },

四，页面效果

a，禁用月份

b，禁用日期

五，完整代码

1，页面查询组件引用

a.引入

import DateSearch from "_c/date-search";
components: {DateSearch},

b.渲染

 <date-search ref="dateSearch">
      <span class="search-label">查询时间</span>
 </date-search>

c.获取时间

 let {S_createTime_GTOE, S_createTime_LTOE} = this.$refs.dateSearch.getDateSearch();
        this.queryParam.endTime =S_createTime_LTOE;
        this.queryParam.startTime=S_createTime_GTOE;

2.时间组件

a.月份组件
