需求:可選擇的時間大于當前時間,不符合條件的全部禁用
以下實現(xiàn)方式可精確到年违诗、月漱凝、日、時诸迟、分茸炒、秒
HTML

<el-form-item label="盤點開始時間" prop="checkStartTime">
      <el-date-picker
        type="datetime"
        placeholder="請選擇開始時間"
        style="width: 100%"
        clearable
        format="yyyy-MM-dd HH:mm:ss"
        :picker-options="pickerOptions"
        v-model="inventoryEdit.checkStartTime"
      ></el-date-picker>
 </el-form-item>

data里

// 選擇開始時間大于等于當前時間
      pickerOptions: {

          const dateTime = new Date();
          const startDateTime = dateTime.setDate(dateTime.getDate() - 1);
          const endDateTime = dateTime.setDate(dateTime.getDate() + 30000); //30000為當前日期之后多少天
          return (
            time.getTime() < new Date(startDateTime).getTime() ||
            time.getTime() > new Date(endDateTime).getTime()
          );
        },
        selectableRange:
        //setMinutes,getMinutes限制分 , 年、月阵苇、日壁公、時、分绅项、秒同理,+1為數(shù)字區(qū)間
        //重點就在這個set get, 漁給了, 魚自己捕吧
          this.parseTime(new Date().setMinutes(new Date().getMinutes() + 1),"{hh}:{ii}:{ss}") + "- 23:59:00",
