javascript - 将数组的数组转换为对象的数组

Question

这是(动态)输入数组:

[
 [1,"Node 1"],
 [2,"Node 2"],
 [3,"Node 3"],
 [4,"Node 4"]
//, Here the elements are going to appear
]

可以改成这样吗？

[
 {id: 1, label: 'Node 1'},
 {id: 2, label: 'Node 2'},
 {id: 3, label: 'Node 3'},
 {id: 4, label: 'Node 4'},
 {id: 5, label: 'Node 5'}
//, Here the elements are going to be add
]

Answer 1

我认为这是您正在寻找的代码

const a = [
   [1,"Node 1"],
   [2,"Node 2"],
   [3,"Node 3"],
   [4,"Node 4"]
]

let objArray = []


a.forEach(element => {
  let obj = {}

  obj.id = element[0]
  obj.label = element[1]

  objArray.push(obj)
  return element
})

console.log(objArray)
