在lodash中添加对象的新属性 [英] Add new properties of object in lodash

问题描述

我有两个对象，我想要将对象A的属性添加到对象B，我尝试使用扩展这不起作用，我是否需要使用不同的东西？

I've two objects and I want to add properties from object A to object B and I try with extend which doesn't work,do I need to use something different ?

a = {
name = "value"
name2 = "value2"
}

b = {
name3 = "value"
name4 = "value2"
}

我希望A包含两者

a = {
name = "value"
name2 = "value2"
name3 = "value"
name4 = "value2"
}

推荐答案

_ .extend （现在称为 _ .assignment ）确实是这样的：

_.extend (now called _.assign) is indeed how you do this:

_.assign(a, b);

实例：

var a = {
name: "value",
name2: "value2"
};

var b = {
name3: "value",
name4: "value2"
};

_.assign(a, b);
document.body.insertAdjacentHTML(
  "beforeend",
  "Result:<pre>" + JSON.stringify(a, null, 2) + "</pre>"
);
