elementUI日期组件限制日期范围 吴小明

限制区间30天：

      pickerMinDate: '',
      pickerOptions: {
        onPick: ({ maxDate, minDate }) => {
          this.pickerMinDate = minDate.getTime()
          if (maxDate) this.pickerMinDate = ''
        },
        disabledDate: (time) => {
          if (this.pickerMinDate !== '') {
            const one = 30 * 24 * 3600 * 1000
            const minTime = this.pickerMinDate - one
            const maxTime = this.pickerMinDate + one
            return time.getTime() < minTime || time.getTime() > maxTime
          }
        }
      }

限制区间30天，不能大于今日：

      pickerMinDate: '',
      pickerOptions: {
        onPick: ({ maxDate, minDate }) => {
          this.pickerMinDate = minDate.getTime()
          if (maxDate) this.pickerMinDate = ''
        },
        disabledDate: (time) => {
          if (this.pickerMinDate !== '') {
            const one = 30 * 24 * 3600 * 1000
            let minTime = this.pickerMinDate - one
            let maxTime = this.pickerMinDate + one
            if (maxTime > new Date()) maxTime = new Date() // 限制不能选择今天之后的日期
            return time.getTime() < minTime || time.getTime() > maxTime
          }
          return time.getTime() > Date.now()
        }
      }

限制区间30天，不能小于今日：

      pickerMinDate: '',
      pickerOptions: {
        onPick: ({ maxDate, minDate }) => {
          this.pickerMinDate = minDate.getTime()
          if (maxDate) this.pickerMinDate = ''
        },
        disabledDate: (time) => {
          if (this.pickerMinDate !== '') {
            const one = 30 * 24 * 3600 * 1000
            let minTime = this.pickerMinDate - one
            let maxTime = this.pickerMinDate + one
            if (minTime < new Date()) minTime = new Date() // 限制不能选择今天之前的日期
            return time.getTime() < minTime || time.getTime() > maxTime
          }
          return time.getTime() < Date.now() - 8.64e7 // 加上 - 8.64e7 就可以选择今天
        }
      }

选择今天及之前的日期：

      pickerOptions: {
        disabledDate: (time) => {
          return time.getTime() > Date.now()
        }
      }

选择今天之前的日期：

      pickerOptions: {
        disabledDate: (time) => {
          return time.getTime() > Date.now() - 8.64e7
        }
      }

选择今天及之后的日期：

      pickerOptions: {
        disabledDate: (time) => {
          return time.getTime() < Date.now() - 8.64e7
        }
      }

选择今天之后的日期：

      pickerOptions: {
        disabledDate: (time) => {
          return time.getTime() < Date.now()
        }
      }

结束日期不能大于开始日期：
