vue 判斷兩個列表是否重複

      // rawValueList 原值

      e.displayValueList.map((item) => {
        if (that.displayValueList.findIndex((preItem) =>
        // 根據preItem中的int_id屬性來判斷這個item是否存在，如果是，返回true，否返回false，繼續下面一條數據的遍歷,以此類推
        // eslint-disable-next-line implicit-arrow-linebreak,brace-style
        // eslint-disable-next-line no-unused-expressions,implicit-arrow-linebreak
          preItem.int_id === item.int_id,
