多封电子邮件的电子邮件验证（以逗号分隔） [英] Email Validation for multiple emails (comma separated)

问题描述

我目前在js中使用以下正则表达式进行电子邮件验证，

其中电子邮件地址可以用逗号分隔或

分号。然而，问题在于我可以输入两封电子邮件

（作为连续播放，没有逗号或分号），只要它以
$ b $结尾b三个字符域，它被认为是有效的。


我想知道是否有办法制作逗号或分号

如果是第二封电子邮件必须地址已存在？

非常感谢任何帮助 - 路易斯


这是脚本：


function checkEmailForErrors（表格，字段）{

var emailFilter2 = /（（[a-zA-Z0-9 \-？\。？] +）@（（[a-zA-Z0-9 \\ \\ -_] + \。）+）（[az]

{2,3}）（\ W？[，;] \ W？（？！$））？） + $ / i;

var emailValue2 = eval（" document。" + Form +"。" + Field +" .valu e"）;

if（！（emailFilter2.test（emailValue2）））{

返回false;

} else {

返回true;

}

}

Hi,
I currently am using the following regex in js for email validation,
in which the email addresses can be separated by commas or
semicolons. The problem, however, lies in that I can type two emails
(as a run-on, with no comma or semicolon), and as long as it ends in a
three character domain, it is accepted as valid.

I wonder if there would be a way to make the comma or semicolon
mandatory if a second email address existed?
Many thanks for any help - Louis

Here is the script:

function checkEmailForErrors (Form,Field) {
var emailFilter2=/(([a-zA-Z0-9\-?\.?]+)@(([a-zA-Z0-9\-_]+\.)+)([a-z]
{2,3})(\W?[,;]\W?(?!$))?)+$/i;
var emailValue2=eval("document."+Form+"."+Field+".valu e");
if (!(emailFilter2.test(emailValue2))) {
return false;
}else{
return true;
}
}

））？）+

/ i;

var em ailValue2 = eval（" document。" + Form +"。" + Field +" .valu e"）;

if（！（emailFilter2.test（emailValue2）））{

返回false;

}否则{

返回true;

}

}

/i;
var emailValue2=eval("document."+Form+"."+Field+".valu e");
if (!(emailFilter2.test(emailValue2))) {
return false;
}else{
return true;
}
}

您可以尝试使用以下正则表达式：

/^ [A-Z0-9 \。 ％ - ] + @ [A-Z0-9\ .-] + \ [AZ] {2,4}（：（：？[;] [A-Z0-9\ ._％ - ] + @ [A-

Z0-9 \ .-] +））？

You can try to use the following regular expression:
/^[A-Z0-9\._%-]+@[A-Z0-9\.-]+\.[A-Z]{2,4}(?:(?:[,;][A-Z0-9\._%-]+@[A-
Z0-9\.-]+))?
