moment——日期格式化常用示例

<template>
  <div id="app" style="text-align: center;">
    <h1>{{ msg | format}}</h1>
  </div>
</template>

<script>
import moment from 'moment'
import 'moment/locale/zh-cn'
moment.locale('zh-cn')
export default {
  name: 'app',
  data () {
    return {
      msg: new Date
    }
  },
  filters:{
    format(val){
      // return moment(val).calendar() //默认为英文、引入后设置格式
      // return moment(val).format('YYYY年MM月DD日') //自定义方案1，简写：LL 或 ll
      // return moment(val).format('YYYY-MM-DD HH:mm:ss') //大写HH为24小时制，小写dd为星期
      // return moment(val).format('hh:mm:ss a') //12小时制
      // return moment(val).format('YYYYMMDDHHmmss') //纯数字日期
      // return moment(val).subtract(1, "days").format("YYYY-MM-DD HH:mm:ss") //1天前(add:后)：weeks、months、years、hours、minutes、seconds
      // return moment(val).format("LLLL") //全中文日期
      // return moment(val).format("dddd") //获取星期
      // return moment(val).valueOf() //完整的时间戳
      // return moment(val).format('X') //秒结尾
      // return moment(val).format('x') //毫秒结尾
      return moment(val).format('LLLL')
    }
  }
}
</script>

 常用时间范围设置：

//获取本日、本周week、本月month、本年year，注意没有yesterday,可以通过subtract（1，'days'）设置，这里带xxx-s！！！
  const startDate = moment().startOf('day').format('YYYY-MM-DD HH:mm:ss'); 
  const startDate = moment().endOf('day').format('YYYY-MM-DD HH:mm:ss');

如果是从今天开始到80年后：

[moment().startOf('day').format('YYYY-MM-DD HH:mm:ss'),moment().endOf('day').add(80, "years").format('YYYY-MM-DD HH:mm:ss')],// 当前时间2019-12-25 00:00:00——2099-12-31 23:59:59

【模板】：

const pickerOptionsTime = {
  shortcuts: [
    {
      text: '昨天',
      onClick (picker) {
        const date = [moment().startOf('day').subtract(1, "days").format('YYYY-MM-DD HH:mm:ss'),moment().endOf('day').subtract(1, "days").format('YYYY-MM-DD HH:mm:ss')]
        picker.$emit('pick', date)
      }
    }, {
      text: '当天',
      onClick (picker) {
        const date = [moment().startOf('day').format('YYYY-MM-DD HH:mm:ss'),moment().endOf('day').format('YYYY-MM-DD HH:mm:ss')]
        picker.$emit('pick', date)
      }
    }, {
      text: '本周',
      onClick (picker) {
        const date = [moment().startOf('week').format('YYYY-MM-DD HH:mm:ss'),moment().endOf('week').format('YYYY-MM-DD HH:mm:ss')]
        picker.$emit('pick', date)
      }
    }
  ]
}

封装的elementUI搜索表单：
