添加到在Javascript

Question

对象的对象我有对象的对象如下：

var people = { 
"fred": {"height": 10, "weight": 190}, 
"mary": {"height": 6, "weight": 120} 
}; 

我想其他项目添加到该对象。具体而言，我想添加以下对象：

var luke = {"height": 8, "weight": 130}; 

为什么我不能这样做使用people.push？如：

people.push(luke) 

Answer 1

你应该做

people["luke"] = luke 

或

people.luke = luke
