在JavaScript中将对象转换为对象数组
假设我们有一个对象，其中包含有关像这样的某些人的数据-
const obj = {
"Person1_Age": 22,
"Person1_Height": 170,
"Person1_Weight": 72,
"Person2_Age": 27,
"Person2_Height": 160,
"Person2_Weight": 56
};我们需要编写一个接受一个这样的对象的JavaScript函数。并且我们的功能应该将有关每个唯一人员的数据分成各自的对象。
因此，上述对象的输出应类似于-
const output = [
{
"name": "Person1",
"age": "22",
"height": 170,
"weight": 72
},
{
"name": "Person2",
"age": "27",
"height": 160,
"weight": 56
}
];示例
为此的代码将是-
const obj = {
"Person1_Age": 22,
"Person1_Height": 170,
"Person1_Weight": 72,
"Person2_Age": 27,
"Person2_Height": 160,
"Person2_Weight": 56
};
const separateOut = (obj = {}) => {
const res = [];
Object.keys(obj).forEach(el => {
const part = el.split('_');
const person = part[0];
const info = part[1].toLowerCase();
if(!this[person]){
this[person] = {
"name": person
};
res.push(this[person]);
}
this[person][info] = obj[el];
}, {});
return res;
};
console.log(separateOut(obj));输出结果
控制台中的输出将是-
[
{ name: 'Person1', age: 22, height: 170, weight: 72 },
{ name: 'Person2', age: 27, height: 160, weight: 56 }
]
