Create a Method on an Object	在对象上创建方法

在对象上创建方法

方法：

必须在对象本身内初始化对象函数。这在以下代码中进行了演示。

let obj = { 
  property1 = 1, 
 
  function1: function() { 
    //Code to be exectued 
  } 
 }; 

解：

let dog = { 
  name: "Spot", 
  numLegs: 4, 
  sayLegs: function() { 
    return "This dog has " + dog.numLegs + " legs."; 
  } 
 }; 
 
 dog.sayLegs();
