this should be correct pattern
这应该是正确的模式
[^@]+@[^@]+\.[a-zA-Z]{2,6}
yes you forgot to consider lower case.
是的，你忘了考虑小写。

The accepted answer won't validate [email protected] In this case not to miss out all those new domain names emails like http://www.iflove.technology/you could use:
接受的答案不会验证 [email protected] 在这种情况下，不要错过所有像http://www.iflove.technology/这样的新域名电子邮件，您可以使用：
[^@]+@[^@]+\.[a-zA-Z]{2,}
Used with input type email it looks like this:
与输入类型的电子邮件一起使用，它看起来像这样：
<input type="email" pattern="[^@]+@[^@]+\.[a-zA-Z]{2,}">
回答by ydaetskcoR
You need to account for lower cases too. Or make it case insensitive. But in reality you should just use:
您也需要考虑小写。或者让它不区分大小写。但实际上你应该只使用：
^.+@.+$
And send a confirmation e-mail to the address that they should follow because e-mail addresses are reasonably complicated and you'll end up blocking stuff you don't intend to with a regex and it doesn't stop someone putting in a fake e-mail address anyway.
并将确认电子邮件发送到他们应该关注的地址，因为电子邮件地址相当复杂，您最终会使用正则表达式阻止您不打算使用的内容，并且不会阻止某人输入假冒电子邮件地址。

It is very difficult to validate Email correctly simply using HTML5 attribute "pattern". If you do not use a "pattern" someone@ will be processed. which is NOT valid email.
仅使用 HTML5 属性“模式”很难正确验证电子邮件。如果您不使用“模式”，某人@ 将被处理。这不是有效的电子邮件。
Using pattern="[a-zA-Z]{3,}@[a-zA-Z]{3,}[.]{1}[a-zA-Z]{2,}[.]{1}[a-zA-Z]{2,}" will require the format to be [email protected]
使用模式="[a-zA-Z]{3,}@[a-zA-Z]{3,}[.]{1}[a-zA-Z]{2,}[.]{1} [a-zA-Z]{2,}" 将要求格式为 [email protected]

Simply remove the patternattribute. The type="email"is enough.
只需删除该pattern属性。该type="email"是足够了。

My solution to override html5 validation type='email'. I run this code after DOM loaded
我的解决方案是覆盖 html5 验证 type='email'。我在加载 DOM 后运行此代码
$(document).ready(function(){
$('input[type=email]').attr('pattern', "^([\w]+[\.]{0,1})+@([\w-]+\.)+[\w]{2,4}$").attr('type', 'text').attr('title', 'Please enter an email address')
})

I'm using this pattern right now, seems to work just fine:
我现在正在使用这种模式，似乎工作得很好：
[a-zA-Z0-9._\-]+@[a-zA-Z0-9.\-]+\.[a-zA-Z]{2,4}
