如果你正在使用NG模式和材料,这就是工作。

vm.validateEmail = '([a-zA-Z0-9_.]{1,})((@[a-zA-Z]{2,})[\\\.]([a-zA-Z]{2}|[a-zA-Z]{3}))';

这就是 node-validator 如何做到:

/^(?:[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+\.)*[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+@(?:(?:(?:[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!\.)){0,61}[a-zA-Z0-9]?\.)+[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!$)){0,61}[a-zA-Z0-9]?)|(?:\[(?:(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\.){3}(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\]))$/

我认为这是最好的解决方案:

/^[^\s@]+@[^\s@]+\.[^\s@]+$/

它允许以下格式:

1.  prettyandsimple@example.com
2.  very.common@example.com
3.  disposable.style.email.with+symbol@example.com
4.  other.email-with-dash@example.com
9.  #!$%&'*+-/=?^_`{}|~@example.org
6.  "()[]:,;@\\\"!#$%&'*+-/=?^_`{}| ~.a"@example.org
7.  " "@example.org (space between the quotes)
8.  üñîçøðé@example.com (Unicode characters in local part)
9.  üñîçøðé@üñîçøðé.com (Unicode characters in domain part)
10. Pelé@example.com (Latin)
11. δοκιμή@παράδειγμα.δοκιμή (Greek)
12. 我買@屋企.香港 (Chinese)
13. 甲斐@黒川.日本 (Japanese)
14. чебурашка@ящик-с-апельсинами.рф (Cyrillic)

它是显而易见的多元化,并允许所有重要的国际角色,同时仍然执行基本的 anything@anything.anything格式,它将阻止技术上允许的空间,但它们是如此罕见,我很高兴做到这一点。

這是從 http://codesnippets.joyent.com/posts/show/1917 偷走的

email = $('email');
filter = /^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
if (filter.test(email.value)) {
  // Yay! valid
  return true;
}
else
  {return false;}

**javascript mail code**

    function ValidateEmail(inputText)
    {
    var mailformat = /^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/;
    if(inputText.value.match(mailformat))
    {
    document.form1.text1.focus();
    return true;
    }
    else
    {
    alert("You have entered an invalid email address!");
    document.form1.text1.focus();
    return false;
    }
    }

只是为了完整性,这里有另一个RFC 2822符合规则。
