如何重新分配对象“获取”方法？

Question

Lets say theres an object with a getter method.

var person = {
 name : "John",
 get title(){
 return "Dr." + this.name
 }
}
>>>person.title
>>>"Dr.John"

I would like to reassign the getter method.

person.title = function (){return "Mr." + this.name}

Is there any way? Or at least create one dynamically or similar workarounds?

You can use Object.defineProperty

 var person = { name: "John", get title() { return "Dr." + this.name } } console.log(person.title) Object.defineProperty(person, "title", { get: function() { return "Mr." + this.name } }); console.log(person.title)
