添加到在Javascript

Question

對象的對象我有對象的對象如下：

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

我想其他項目添加到該對象。具體而言，我想添加以下對象：

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

爲什麼我不能這樣做使用people.push？如：

people.push(luke) 

Answer 1

你應該做

people["luke"] = luke 

或

people.luke = luke
