如何将此数组转换为JavaScript对象？

Question

下面的代码循环遍历JavaScript对象，并仅收集数组属性：

const building = this.building
let panoramaList = []
for (let key in building) {
  const panoramas = building[key]
  if (Array.isArray(panoramas)) {
    panoramaList.push({ [key]: panoramas })
  }
}
console.log(panoramaList)

换句话说，它是这样的：

{
  name: '',
  description: ''.
  livingroom: Array[0],
  study: Array[1],
  bedroom: Array[0]
}

然后把它变成这样：

[
  { livingroom: Array[0] },
  { study: Array[1] },
  { bedroom: Array[0] }
]

然而，我需要生成的是：

{
  livingroom: Array[0],
  study: Array[1],
  bedroom: Array[0]
}

如何做到这一点呢？

Answer 1

尝尝这个

var output = Object.keys(building).map(function(val){ return { val : building[val] } });

对于最终的输出

var panoramaList = {}
Object.keys(building).forEach(function(val){ 
  if ( Array.isArray(building[val] )
  {
    panoramaList[val] = building[val];
  }
});

Answer 2

更改此设置：

const building = this.building
let panoramaList = []
for (let key in building) {
  const panoramas = building[key]
  if (Array.isArray(panoramas)) {
    panoramaList.push({ [key]: panoramas })
  }
}
console.log(panoramaList)

要这样做：

const building = this.building
let panoramaList = {}
for (let key in building) {
  const panoramas = building[key]
  if (Array.isArray(panoramas)) {
    panoramaList[key]=panoramas
  }
}
console.log(panoramaList)

Answer 3

使用Object.keys并尝试如下所示：

var input = {} //...your input array
var keys = Object.keys(input);
var result = {};

keys.forEach(function (key) {
    if (Array.isArray(input[key])) {
        result[key] = input[key];
    }
});
