包括电子邮件地址验证，以便电子邮件具有@ gmail.com扩展名 [英] Include validation for email address so that the email has @gmail.com extension

问题描述

任何人都可以帮我完成这项任务。我有一个接受电子邮件地址的文本框。我们需要验证电子邮件地址，使其只有@ gmail.com扩展名。如果电子邮件地址无效，我需要使用红色背景制作div，并显示电子邮件无效的错误消息。

Can anyone help me to do this task. I have got a textbox that accept the email address. We need to validate the email address such that it has only "@gmail.com " extension. If the email address is not valid I need to make the div with red background and also display an error message that the email is not valid.

<div class="detailsRow" id="VAREmail">
           <div class="detailsLabel">
               @Html.LabelFor(m => m.VAREmail, Strings.VAREmail)
           </div>
           @Html.TextBoxFor(m => m.VAREmail, new { style = "width:50%" })
           @Html.ValidationMessageFor(m => m.VAREmail)
       </div>

我尝试了什么：



我尝试使用javascript但是我不能使它成为



var email = document.getElementById（VAREmail）。next（）。value;

var filter = ^（？ i）[A-Z0-9 ._％+ - ] + @（gmail.com）;

if（！filter.test（email））

{

document.getElementById（VAREmail）。style.backgroundColor =maroon;

}

What I have tried:

I tried using a javascript but I couldn't make it

var email = document.getElementById("VAREmail").next().value;
var filter = ^(?i)[A-Z0-9._%+-]+@(gmail.com);
if(!filter.test(email))
{
document.getElementById("VAREmail").style.backgroundColor = "maroon";
}

推荐答案

试试正则表达式：

Try a regex:

^[\w!#

％&'* + - / =？^ _ `{|}〜] {1,64} @ gmail.com

%&'*+-/=?^_`{|}~]{1,64}@gmail.com

应该这样做。
