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

本文关键字：提取 电子邮件地址 文本 jquery 使用      更新时间：2023-09-26

我有下面的文本：

sdabhikagathara@rediffmail.com, "assdsdf" <dsfassdfhsdfarkal@gmail.com>, "rodnsdfald ferdfnson" <rfernsdfson@gmail.com>, "Affdmdol Gondfgale" <gyfanamosl@gmail.com>, "truform techno" <pidfpinfg@truformdftechnoproducts.com>, "NiTsdfeSh ThIdfsKaRe" <nthfsskare@ysahoo.in>, "akasdfsh kasdfstla" <akashkatsdfsa@yahsdfsfoo.in>, "Bisdsdfamal Prakaasdsh" <bimsdaalprakash@live.com>,; "milisdfsfnd ansdfasdfnsftwar" <dfdmilifsd.ensfdfcogndfdfatia@gmail.com>

此处电子邮件按,或;进行分隔。我想提取上面出现的所有电子邮件，并将它们存储在数组中。有没有什么简单的方法可以使用regex直接获取所有电子邮件？

以下是如何实现这一点：

HTML

<p id="emails"></p>

JavaScript

var text = 'sdabhikagathara@rediffmail.com, "assdsdf" <dsfassdfhsdfarkal@gmail.com>, "rodnsdfald ferdfnson" <rfernsdfson@gmal.com>, "Affdmdol Gondfgale" <gyfanamosl@gmail.com>, "truform techno" <pidfpinfg@truformdftechnoproducts.com>, "NiTsdfeSh ThIdfsKaRe" <nthfsskare@ysahoo.in>, "akasdfsh kasdfstla" <akashkatsdfsa@yahsdfsfoo.in>, "Bisdsdfamal Prakaasdsh" <bimsdaalprakash@live.com>,; "milisdfsfnd ansdfasdfnsftwar" <dfdmilifsd.ensfdfcogndfdfatia@gmail.com> datum eternus hello+11@gmail.com';    
function extractEmails (text)
{
    return text.match(/([a-zA-Z0-9._+-]+@[a-zA-Z0-9._-]+'.[a-zA-Z0-9._-]+)/gi);
}
     
$("#emails").text(extractEmails(text).join(''n'));

结果

sdabhikagathara@rediffmail.com,dsfassdfhsdfarkal@gmail.com,rfernsdfson@gmal.com,gyfanamosl@gmail.com,pidfpinfg@truformdftechnoproducts.com,nthfsskare@ysahoo.in,akashkatsdfsa@yahsdfsfoo.in,bimsdaalprakash@live.com,dfdmilifsd.ensfdfcogndfdfatia@gmail.com,hello+11@gmail.com

来源：从批量文本中提取电子邮件(使用正则表达式、JavaScript和jQuery(

此处演示1

演示2此处使用jQuery的每个迭代器函数

您可以使用以下正则表达式：

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;

你可以这样提取电子邮件：

('sdabhikagathara@rediffmail.com, "assdsdf" <dsfassdfhsdfarkal@gmail.com>, "rodnsdfald ferdfnson" <rfernsdfson@gmail.com>, "Affdmdol Gondfgale" <gyfanamosl@gmail.com>, "truform techno" <pidfpinfg@truformdftechnoproducts.com>, "NiTsdfeSh ThIdfsKaRe" <nthfsskare@ysahoo.in>, "akasdfsh kasdfstla" <akashkatsdfsa@yahsdfsfoo.in>, "Bisdsdfamal Prakaasdsh" <bimsdaalprakash@live.com>,; "milisdfsfnd ansdfasdfnsftwar" <dfdmilifsd.ensfdfcogndfdfatia@gmail.com>').match(re);
//["sdabhikagathara@rediffmail.com", "dsfassdfhsdfarkal@gmail.com", "rfernsdfson@gmail.com", "gyfanamosl@gmail.com", "pidfpinfg@truformdftechnoproducts.com", "nthfsskare@ysahoo.in", "akashkatsdfsa@yahsdfsfoo.in", "bimsdaalprakash@live.com", "dfdmilifsd.ensfdfcogndfdfatia@gmail.com"]

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"。GMAIL支持电子邮件地址+randomtext@gmail.com.

我已更新到：

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

根据Regexr.com ，以下函数符合RFC2822

ES5:

var extract = function(value) {
   var reg = /[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:'.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?'.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?/g;
   return value && value.match(reg);
}

ES6:

const reg = /[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:'.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?'.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?/g
const extract = value => value && value.match(reg)

Regexr社区源

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" <foo@domain.com>, ..., "And so on" <andsoon@gmx.net>'
var emails = GetEmailsFromString(str)

源

您不需要jQuery；JavaScript本身支持内置正则表达式。

查看正则表达式，了解有关在JavaScript中使用正则表达式的更多信息。

除此之外，我想你会在Stack Overflow上的其他地方找到问题的确切答案-如何在javascript 中从字符串中查找电子邮件和名称

 const = regex = /'S+[a-z0-9]@[a-z0-9'.]+/img
"hello sean@example.com how are you? do you know bob@example.com?".match(regex)

这里的一堆答案包括小写/大写字母[a-zA-Z]和不敏感的正则表达式标志i，这是无稽之谈。

  • i修饰符：不敏感。不区分大小写的匹配(忽略[a-zA-Z]的大小写(
  • 'd匹配一个数字(相当于[0-9](，因为域扩展不以数字字符结尾(

因此，与'd令牌相结合。我们得到了一个更加简洁优雅的句子。

/[a-z'd._+-]+@[a-z'd._-]+/gi

Demo

let input = 'sdabhikagathara@rediffmail.com, "assdsdf" <dsfassdfhsdfarkal@gmail.com>, "rodnsdfald ferdfnson" <rfernsdfson@gmail.com>, "Affdmdol Gondfgale" <gyfanamosl@gmail.com>, "truform techno" <pidfpinfg@truformdftechnoproducts.com>, "NiTsdfeSh ThIdfsKaRe" <nthfsskare@ysahoo.in>, "akasdfsh kasdfstla" <akashkatsdfsa@yahsdfsfoo.in>, "Bisdsdfamal Prakaasdsh" <bimsdaalprakash@live.com>,; "milisdfsfnd ansdfasdfnsftwar" <dfdmilifsd.ensfdfcogndfdfatia@gmail.com>'
function get_email(string) {
  return string.match(/[a-z'd._+-]+@[a-z'd._-]+/gi)
};
$('#output').html(get_email(input).join('; '));
