Question

我有一组用连字符分隔的ID，最后6个字符包含字母数字值和最后的一些特殊字符，其中只允许使用数字值。如下所示：

YUIO-10GB-BG4   ==> Should match

U-VI1.1-100-WX-Y9  ==> Should match

1-800-553-6387  ==> Shouldn't match because all are digits

T-Series  ==> Shouldn't match as all only 2 letters are capital

我正在尝试下面给出的以下规则，但是面临一些测试查询的困难..

((?=\S{6,})[A-Z]{1,}(([A-Z0-9./+~]+){0,}-){1,}[A-Z0-9./+~]+=*)

Answer 1

您可以使用以下正则表达式来获取所有匹配项，然后过滤掉那些不包含/[A-Z]/正则表达式字母的字符：

/(?:^|\s)(?=\S{6,})(?=\S*[A-Z])([A-Z0-9./+~]+(?:-[A-Z0-9./+~]+)+=*)(?!\S)/g

请参阅regex demo。

(?:^|\s) - 字符串或空格的开头
(?=\S{6,}) - 6个或更多字符
(?=\S*[A-Z]) - 在0 +非空白字符后必须至少有1个大写ASCII字母
([A-Z0-9./+~]+(?:-[A-Z0-9./+~]+)+=*) - 第1组：
- [A-Z0-9./+~]+ - 1+大写ASCII字母，数字，.，/，+，~
- (?:-[A-Z0-9./+~]+)+ - 出现1次以上：
  - - - -字符
  - [A-Z0-9./+~]+ - 1+大写ASCII字母，数字，.，/，+，~
- =* - 0 + =个符号
(?!\S) - 字符串的空格或结尾。参见JS演示：

var m, res=[];
var rx = /(?:^|\s)(?=\S{6,})(?=\S*[A-Z])([A-Z0-9./+~]+(?:-[A-Z0-9./+~]+)+=*)(?!\S)/g;
while(m=rx.exec(s)) {
    res.push(m[1]);
}
console.log(res);
