Question

const images =[
  { uri: 'images1' }, 
  { uri: 'images2' }, 
  { uri: 'images3' }, 
  { uri: 'image4' }, 

]

我希望将键添加到每个对象

const newimages =[
  { source: { uri: 'images1' } },
  { source: { uri: 'images2' } },
  { source: { uri: 'images3' } },
  { source: { uri: 'images4' } }
]

请帮助我，因为我是这个编程领域的新手。

Answer 1

使用SELECT RENTER.RENTER_ID, RENTER_LNAME, Round((Count(DEP_ID)+1)/APART_BED) AS "PEOPLE / BEDROOM" FROM RENTER JOIN DEPENDENT ON RENTER.RENTER_ID = DEPENDENT.RENTER_ID JOIN LEASE ON LEASE.RENTER_ID = RENTER.RENTER_ID JOIN APARTMENT ON APARTMENT.APART_NUM = LEASE.APART_NUM WHERE RENTER_ID = ((LEASE_END) = '30-JUN-18') ORDER BY RENTER_ID;根据元素将一个数组转换为另一个数组：

.map

Answer 2

您想使用地图：

BufferedReader br = new BufferedReader(new FileReader("java_module_name/src/file_name.txt"));

Answer 3

欢迎使用JavaScript！
也许你可以尝试使用这样的for循环：

var images =[
  { uri: 'images1' }, 
  { uri: 'images2' }, 
  { uri: 'images3' }, 
  { uri: 'image4' }, 

];

var newImages = [];

for (i = 0; i < images.length; i++){
  newImages.push({
    source: images[i]
  })
}

console.log(newImages)

将新键添加到数组对象javascript
