我有一个像这样的对象数组:

我需要将其转换为以下格式:

I need to convert it to the following format:

使用JavaScript怎么可能?

推荐答案

您可以使用

You can use .map

var data = [
  {"key":"fruit","value":"apple"},
  {"key":"color","value":"red"},
  {"key":"location","value":"garden"}
];

var result = data.map(function (e) {
  var element = {};
  element[e.key] = e.value;
  
  return element;
});

console.log(result);

如果您使用 ES2015 ，也可以这样做

also if you use ES2015 you can do it like this

var result = data.map((e) => {
   return {[e.key]: e.value};
});
