1）普通函数实现
function cloneObject(obj) {
if (obj === null || typeof obj !== 'object') {
return obj;
}
var temp = obj.constructor(); // give temp the original obj's constructor
for (var key in obj) {
temp[key] = cloneObject(obj[key]);
}
return temp;
}
var bob = {
name: "Bob",
age: 32
};
var bill = cloneObject(bob);
bill.name = "Bill";
console.log(bob);
console.log(bill);
2)通过json方法实现
var bob = {
name: "Bob",
age: 32
};
var bill = (JSON.parse(JSON.stringify(bob)));
bill.name = "Bill";
console.log(bob);
console.log(bill);
3）jquery中的$.extend
var bob = {
name: "Bob",
age: 32
};
var bill = $.extend(true, {}, bob);
bill.name = "Bill";
console.log(bob);
console.log(bill);
