使用choosedSameDisks方法处理所有的逻辑；

function choosedSameDisks(productDetailObj, moboShoppingList)  {
    // const { moboShoppingList } = this.state;
    //A B C A A -> A : AAA
    const chooseTaocanId = productDetailObj.mealItemId;
    const chooseMenuId = productDetailObj.menuId;
    const chooseItemList = productDetailObj.mealItemList;
    const chooseItemGroupIdList = chooseItemList.map((item) => item.groupId);
    console.log("moboShoppingList", moboShoppingList);
    let isNewTaocan = true;
    for (let index = 0; index < moboShoppingList.length; index++) {
      const taocan = moboShoppingList[index];

      if (taocan.mealItemList == null) {
        continue;
      }

      //先判断套餐
      const taocanId = taocan.mealItemId;
      const menuId = taocan.menuId;
      if (taocanId === chooseTaocanId && menuId === chooseMenuId) {
        //单商品

        const itemList = taocan.mealItemList;
        if (itemList.length === chooseItemList.length) {

            const groupId = item.groupId;
            if (!chooseItemGroupIdList.includes(groupId)) {
              break;

          }
