如何向此对象添加元素 [英] How can I add elements to this object

问题描述

如果我有这个结构

var data = 
{ 
    "people": [ 
      { "name" : "John", "id" : 1 },
      { "name" : "Marc", "id" : 2 }
    ] 
}

我想在JavaScript中为此添加更多元素，特别是在jQuery中，然后像这样发送它

I want to add more elements to this, in JavaScript, specifically in jQuery to then send it like this

var dataString = JSON.stringify(data);
$.post('some.php', { data: dataString}, showResult, "text");

推荐答案

var data = 
{ 
    "people": [ 
      { "name" : "John", "id" : 1 },
      { "name" : "Marc", "id" : 2 }
    ] 
}
data["people"].push({"name": "foo", "id": 3});

console.log(data);
