javascript - 按@符号按字符串拆分数组对象

Question

我有流动数组对象

let old_array = {
 "valone":  "facebook",
 "notification": "new message! @user1@example.com @user2@example.com"
}

我想让所有带@的用户像下面一样登录到新数组中

let new_array = {"user1@example.com", "user2@example.com"}

知道如何做到这一点我有用户数组拆分我只能收到带有@符号的电子邮件。

let new_array = old_array .split("@");

Answer 1

试试这个:

let old_array = {
 "valone":  "facebook",
 "notification": "new message! @user1@example.com @user2@example.com"
}

const result =  old_array.notification.match(/(?<=@)(\w*@\w*.\w*)/g);

console.log(result);
