javascript - 将数组转换为键值对

Question

我有一个数组

[
{"field" : "flight1", "value" : "123"},
{"field" : "flight2", "value" : "456"}
]

是否可以成为键值对？

{
"flight1" : "123",
"flight2" : "456"
}

Answer 1

您可以使用 reduce() 并返回对象作为结果。

var arr = [{"field" : "flight1", "value" : "123"},{"field" : "flight2", "value" : "456"}]

var result = arr.reduce(function(r, e) {
  r[e.field] = e.value;
  return r;
}, {});

console.log(result)
