How to determine equality for two JavaScript objects? 如何肯定兩個JavaScript對象的相等性？ (59 answers) （59個回答）

Closed 3 years ago . 3年前關閉。

What is the best way to compare objects in JavaScript? 在JavaScript中比較對象的最佳方法是什麼？

Example: 例：

var user1 = {name : "nerd", org: "dev"};
var user2 = {name : "nerd", org: "dev"};
var eq = user1 == user2;
alert(eq); // gives false

I know that two objects are equal if they refer to the exact same object , but is there a way to check if they have the same attributes' values? 我知道兩個對象若是引用徹底相同的對象 ， 則相等 ，可是有沒有辦法檢查它們是否具備相同的屬性值？

The following way works for me, but is it the only possibility? 如下方法對我有用，但這是惟一的可能性嗎？

var eq = Object.toJSON(user1) == Object.toJSON(user2);
alert(eq); // gives true
