代码如下
const obj = {
name: 'zhangsan',
age: 18,
address: {
email: '1011@qq.com',
phone: '10086',
address2: {
age: 20
}
}
}
const obj2 = deepCope(obj);
obj.address.email = 'lisi'
console.log(obj)
console.log(obj2)
function deepCope(obj = {}) {
if (obj !== 'obj' || obj == null) {
return obj
}
//初始化结果
let result
if (obj instanceof Array) {
result = []
}else {
result = {}
}
for (let key in obj) {
if (obj.hasOwnProperty(key)) {
result[key] = deepCope(obj[key]);
}
}
return result
}
