我有这个:
const id = speakerRec.id;
const firstName = speakerRec.firstName;
const lastName = speakerRec.lastName;
我认为有这样的事情,但不记得了。
const [id, firstName, lastName] = speakerRec;
您需要
使用 {}
来解构对象属性:
const {id, firstName, lastName} = speakerRec;
[]
用于数组解构:
const [one, two, three] = [1, 2, 3];
示范:
const speakerRec = {
id: "mySpeaker",
firstName: "Jack",
lastName: "Bashford"
};
const { id, firstName, lastName } = speakerRec;
console.log(id);
console.log(firstName);
console.log(lastName);
const [one, two, three] = [1, 2, 3];
console.log(one);
console.log(two);
console.log(three);
它是一个对象,所以使用对象解构(不是数组解构(:
const { id, firstName, lastName } = speakerRec;
