<el-date-picker
            v-model="searchForm.dateRange"
            type="daterange"
            :clearable="false"
            range-separator="至"
            start-placeholder="開始日期"
            end-placeholder="結束日期"
            value-format = "yyyy-MM-dd"
            :picker-options="pickerOptions"
          ></el-date-picker>

　　

data() {
      minDate:'',
      maxDate:'',
      pickerOptions: {
        onPick: ({ maxDate, minDate }) => {         
         this.minDate = minDate
         this.maxDate = maxDate
        },
        disabledDate: (time) => { //查詢時間跨度為31天
          if(this.minDate){
            let range = 31 * 24 * 3600 * 1000
            return time.getTime() > Date.now() || time.getTime() > (this.minDate.getTime() + range) || time.getTime() < (this.minDate.getTime() - range)
          }
          return time.getTime() > Date.now()
        }
      }
}
