Question

我必须检索一个对象并将其分配给另一个对象。但是在新对象中，总是仅存储最后一个项目。

我尝试了object.entries键方法，但没有任何效果。代码：https://codesandbox.io/s/k3p7j07x8o

let subject = {};
const obj = { a: 5, b: 4, c: 9 };
for (const [key, value] of Object.entries(obj)) {
    console.log(`${key} ${value}`);
    //console.log(subject); // Here itself it's printing the last element
    subject.value = key;
    subject.text = value;
    console.log(subject.value + subject.text); // This showing the correct element
    console.log(subject); // This one showing the last elements
}

您可以使用以下语法：

let subject = Object.assign({}, obj}
console.log(subject)

或

let subject = {};
Object.assign(subject, obj);
console.log(subject)

检索对象值并将其分配给ReactJS中的另一个对象
