分配值，而不是在javascript中引用 [英] Assign value not reference in javascript

问题描述

我在用javascript分配对象时遇到了一些问题.

I am having a little problem assigning objects in javascript.

看看这个示例代码，它再现了我的问题.

take a look at this sample code that reproduces my problem.

var fruit = {
   name: "Apple"
};

var vegetable = fruit;
vegetable.name = "potatoe";
console.log(fruit);

它记录

Object {name: "potatoe"}

如何将值(不是对象的引用)分配给另一个对象?

How can I assign the value not the reference of an object to another object?

推荐答案

您可以使用

var fruit = {
   name: "Apple"
};

var vegetable = Object.assign({}, fruit);
vegetable.name = "potatoe";
console.log(fruit);
