Javascript 使用 jquery 从批量文本中提取所有电子邮件地址

Extract all email addresses from bulk text using jquery

提问by Milind Anantwar

I'm having the this text below:

我有下面的文字：

[email protected], "assdsdf" <[email protected]>, "rodnsdfald ferdfnson" <[email protected]>, "Affdmdol Gondfgale" <[email protected]>, "truform techno" <[email protected]>, "NiTsdfeSh ThIdfsKaRe" <[email protected]>, "akasdfsh kasdfstla" <[email protected]>, "Bisdsdfamal Prakaasdsh" <[email protected]>,; "milisdfsfnd ansdfasdfnsftwar" <[email protected]>

Here emails are seprated by ,or ;. I want to extract all emails present above and store them in array. Is there any easy way using regex to get all emails directly?

这里的电子邮件由,或分隔;。我想提取上面存在的所有电子邮件并将它们存储在数组中。有没有什么简单的方法可以使用正则表达式直接获取所有电子邮件？

You can use this regex:

您可以使用此正则表达式：

var re = /(([^<>()[\]\.,;:\s@\"]+(\.[^<>()[\]\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))/g;

You can extract the e-mails like this:

您可以像这样提取电子邮件：

('[email protected], "assdsdf" <[email protected]>, "rodnsdfald ferdfnson" <[email protected]>, "Affdmdol Gondfgale" <[email protected]>, "truform techno" <[email protected]>, "NiTsdfeSh ThIdfsKaRe" <[email protected]>, "akasdfsh kasdfstla" <[email protected]>, "Bisdsdfamal Prakaasdsh" <[email protected]>,; "milisdfsfnd ansdfasdfnsftwar" <[email protected]>').match(re);

//["[email protected]", "[email protected]", "[email protected]", "[email protected]", "[email protected]", "[email protected]", "[email protected]", "[email protected]", "[email protected]"]

Just an update to the accepted answer. This does not work for "plus" signs in the email address. GMAIL supports [email protected].

只是对已接受答案的更新。这不适用于电子邮件地址中的“加号”符号。GMAIL 支持 [email protected]。

I've updated to:

我已经更新为：

return text.match(/([a-zA-Z0-9._+-]+@[a-zA-Z0-9._-]+\.[a-zA-Z0-9._-]+)/gi);

You don't need jQuery for that; JavaScript itself supports regexes built-in.

你不需要 jQuery；JavaScript 本身支持内置的正则表达式。

Have a look at Regular Expressionfor more info on using regex with JavaScript.

看看正则表达式对使用正则表达式使用JavaScript的更多信息。

function GetEmailsFromString(input) {
  var ret = [];
  var email = /\"([^\"]+)\"\s+\<([^\>]+)\>/g

  var match;
  while (match = email.exec(input))
    ret.push({'name':match[1], 'email':match[2]})

  return ret;
}

var str = '"Name one" <[email protected]>, ..., "And so on" <[email protected]>'
var emails = GetEmailsFromString(str)
