验证逗号分隔的电子邮件列表 [英] Validate a comma separated email list

问题描述

我试图提出一个正则表达式来验证逗号分隔的电子邮件列表。

我想首先验证完整的列表，然后拆分（;），然后从拆分中修剪每个数组值（每个电子邮件）。 / p>

我想验证以下表达式：

  EMAIL，EMAIL - > Ok 
 EMAIL，EMAIL  - > Ok 
 EMAIL，EMAIL  - > Ok 
 EMAIL，EMAIL  - >错误
 EMAIL，notAnEmail，EMAIL  - >错误
  

我知道验证电子邮件有很多复杂的表达式，但我不需要任何花哨，这只是适用于我： /\S+@+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++像简单的JS，不是jQuery。谢谢。

编辑：我已经考虑过拳头验证然后拆分，但是我已经尝试过的表达式，这将被验证为两个正确的电子邮件： / p>

  EMAIL，EMAIL。 EMAIL 
  

我想像每个电子邮件一样验证列表本身。

解决方案

一个更简单的方法是先分割字符串：

  var emails = emailList.split（，）; 
  

这将创建一个数组。然后，您可以遍历数组，并检查元素是否不为空，还有一个有效的emailadres。

  var valid = true; 
 var regex = /^(([^<>()[\]\\,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, （）[\] \\;：。\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，...}））$ /。对于（var i = 0; i  if（emails [i] ==||！regex.test（emails [i]），
 
 ））{
 valid = false; 
} 
} 
  

注意：我得到了正则表达式从这里

I'm trying to come up with a regular expression to validate a comma separated email list.

I would like to validate the complete list in the first place, then split(";"), then trim each array value (each email) from the split.

I would like to validate the following expressions:

EMAIL,EMAIL  --> Ok
EMAIL, EMAIL  --> Ok
EMAIL , EMAIL  --> Ok
EMAIL , , EMAIL  --> Wrong
EMAIL , notAnEmail , EMAIL  --> Wrong

I know there's many complex expressions for validating emails but I don't need anything fancy, this just works for me: /\S+@\S+\.\S+/;

I would like plain and simple JS, not jQuery. Thanks.

Edit: I've already considered fist validate then split, but with the expressions I've tried so far, this will be validated as two correct emails:

EMAIL, EMAIL  .  EMAIL

I would like to validate the list itself as much as every email.

解决方案

An easier way would be to split the string first:

var emails = emailList.split(",");

This will create an array. You can then iterate over the array and check if the element is not empty and a valid emailadres.

var valid = true;
var regex = /^(([^<>()[\]\\.,;:\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,}))$/;

for (var i = 0; i < emails.length; i++) {
     if( emails[i] == "" || ! regex.test(emails[i])){
         valid = false;
     }
}

note: I got the the regex from here
