          ]
        },
        ]
      }
obj1.stockRegisterDetailList = obj1.stockRegisterDetailList.map(v=>v.sourceCodeList.map(v1=>({...v,...v1}))).flat()
obj1

回答：

你想要的数据结构有问题，stockRegisterDetailList里的项有个键checkStatus重复了。
这里的实现以子级的值为准。

js">const obj2 = {
    ...obj1,
    stockRegisterDetailList: obj1
        .stockRegisterDetailList
        .flatMap(({ sourceCodeList, ...parent }) =>
            sourceCodeList.map(child => ({ ...parent, ...child })),
        ),
};
