Question

我有一些数据，我已将其转换为对象数组，如：

[{"name": "aa", "birth":"19990101"},
{"name": "bb", "birth":"19990102"},
{"name": "cc", "birth":"19990103"}];

我想将其转换为这样的对象：

{"aa":"19990101","bb":"19990102","cc":"19990103"};

最好的方法是什么？谢谢！

Answer 1

您可以使用一些销毁并将值分配给给定的密钥。

＆＃13;

var array = [{ name: "aa", birth: "19990101" }, { name: "bb", birth: "19990102" }, { name: "cc", birth: "19990103" }],
    object = array.reduce((r, { name, birth }) => (r[name] = birth, r), {});

console.log(object);

＆＃13;

Object.assign与spread syntax ...

＆＃13;

var array = [{ name: "aa", birth: "19990101" }, { name: "bb", birth: "19990102" }, { name: "cc", birth: "19990103" }],
    object = Object.assign({}, ...array.map(({ name, birth }) => ({ [name]: birth })));

console.log(object);

Answer 2

您只需使用reduce，

即可

var x = [{"name": "aa", "birth":"19990101"},
{"name": "bb", "birth":"19990102"},
{"name": "cc", "birth":"19990103"}];

var result = x.reduce((a, b) => (a[b['name']] = b['birth'], a), {});

Answer 3

试试这个

var a = [{"name": "aa", "birth":"19990101"},
{"name": "bb", "birth":"19990102"},
{"name": "cc", "birth":"19990103"}];

var map = {}; a.forEach( function(item){ map[item.name] = item.birth; })

console.log(map);

Answer 4

另一种方式可能是：

＆＃13;

var values =[
  {"name": "aa", "birth":"19990101"},
  {"name": "bb", "birth":"19990102"},
  {"name": "cc", "birth":"19990103"}
];

var result = [];

for(var i = 0; i < values.length; i++){
    var item = {};
    item[values[i].name] = values[i].birth;
    result.push(item);
}

console.log(result);
