通过合并两个集合lookup并通过 unwind 打开附加数据（结果）后，我们得到以下结果：
{
_id: new ObjectId(''),
'one': [ ],
'two': [ ],
result: {
_id: new ObjectId(''),
'three': [ ],
'four': [ ],
'five': [ ]
}
}
您希望结果如下所示：
{
_id: new ObjectId(''),
'one': [ ],
'two': [ ],
'three': [ ],
'five': [ ]
}
const name = 'Sydorenko'
const arr = [
['Азаров'],
['Сидоренко', 'Sydorenko'],
['Хоменко']
]
const res = arr.map(item => {
for (const elem of item) {
if (elem === name) {
return item
}
}
})
console.log(res)
我们有一个数组名称
let name = [
['Ободович', 'Иван'],['Булий' , 'Андрей'],['Булий', 'Андрей']
]
let res = name.forEach((elem) => {
let data = Object.create(null, {lastName: {value:''}, firstName: {value:''})
data.lastName = elem[0];
data.firstName = elem[1]
})
console.log(res)
期待
res = [
{lastName:'Ободович', firstName:'Иван'},
{lastName:'Булий', firstName:'Андрей'},
{lastName:'Булий', firstName:'Андрей'}
]
