ES6深层嵌套对象分解 [英] ES6 deep nested object destructuring

问题描述

我有一个名为this.props的对象，其中包含

I have an object called this.props which contains

{
 actions: Object,
 dirty: false,
 form: "Statement",
 autofill: functon(),
 **statement: Object**
}

statement包含

{
 firstName: "John"
 lastName: "Peter"
 isConfirmed: true
}

我想使用es6解构在同一行中提取statement对象和isConfirmed属性

I would like to extract statement object and the isConfirmed property in the same line using es6 destructuring

我尝试过

const { statement: isConfirmed, isAdmin } = this.props

当我执行let a = isConfirmed, b = statement

推荐答案

我想在同一行中提取语句对象和isConfirmed属性

I would like to extract statement object and the isConfirmed property in the same line

const { statement: { isConfirmed }, statement } = this.props;

这样，您可以同时获取isConfirmed和整个statement对象.

That way you get both isConfirmed and the whole statement object.
