javascript - 使用 javascript 从给定字符串获取电子邮件 ID

Question

我的文本框中有一个值 (a)。我只想使用 Javascript 从给定的字符串获取电子邮件 ID(我不想使用任何 JS 框架)。

(a) xxx@gmail.com (Blig fun), yyy@gmail.info (LOl)

I need the output like 

xxx@gmail.com
yyy@gmail.info 

Answer 1

尝试-

var tbstring = '(a) xxx@gmail.com (Blig fun), yyy@gmail.info (LOl)';
result = tbstring.match(/\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b/ig);
alert(result.join('\n'));

电子邮件正则表达式取自 RegEx Buddy 库，并附带以下条款 -

Does not match email addresses using an IP address instead of a domain name.

Does not match email addresses on new-fangled top-level domains with more than 4 letters such as .museum. Including these increases the risk of false positives when applying the regex to random documents.
