对象的深度克隆方法

对象的深度克隆方法

function deepclone(obj) {

if (typeof obj === ‘object’ && obj !== null) {

if (obj instanceof array) {

let newarr = [];

ob上点j.foreach(item => {

newarr.push(item);

})

return newarr;

} el if (obj instanceof object) {

let newobj = {};

for (let key in obj) {

if (obj[key] instanceof (object) && !obj[key] instanceof function) {

console.log(key);

newobj[key] = arguments.callee(obj[key]);

} el {

newobj[key] = obj[key];

}

}

return newobj;

}

} el {

return;

}

}

方法2:方法1的简化版

functio普通的一天n deepclone2(obj) {

if (typeof obj === ‘object’ && obj !== null) {

let result = obj instanceof array [] : {};

for (let key in obj) {

result[key] = typeof obj[key] === ‘object’讲述红色故事; && !obj[key] instanceof function arguments.callee(obj[key]) : obj[key];

}

return res排球打几局ult;

} el {

return;

}

}

方法3：借助object.assign()和object.create()

function deepclone3(obj) {

let proto = object.getprototypeof(obj);

let result = object.assign({}, object.create(proto), obj);海尔企业文化

return result;

}
