用@符号按字符串分割数组对象

Question

我有流动的数组对象

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

我想打破让所有具有@符号的用户进入像下面这样的新数组

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

任何想法如何做到这一点，我有用户数组拆分即时消息只能用@符号获取电子邮件。

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

Answer 1

尝试这个：

 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); 

Answer 2

您必须在old_array拆分字符串。 尝试这个：

 let old_array = { "valone": "facebook", "notification": "new message! @user1@example.com @user2@example.com" } let notification = old_array["notification"]; //Get notification-property let email_string = notification.substring(notification.indexOf("@")).trim(); //Get rid of the message let email_array = email_string.split(" "); //Split by " " to get the different emails console.log(email_array); 

Answer 3

您可以通过搜索@然后加上非空格来匹配电子邮件。

 var string = 'new message! @user1@example.com @user2@example.com', emails = string.match(/@\\S+/g); console.log(emails);
