我需要使用正则表达式来匹配特定的关键字和最接近的“，”字符。这是我的示例字符串：

ersion: V3  Subject: EMAILADDRESS=[e-mail], GIVENNAME=Blob, SURNAME=Bloby, CN=B dddddddddddd, O=sd, C=IR  Signature Algorithm: SHA1withRSA, OID = 1.2.840.113549.1.1.5  Key:  Sun RSA public key, 2048 bits  modulus

现在，我需要匹配EMAILADDRESS和next之间的单词，即“ [e-mail]”（对于这两点之间的单词没有限制，它们可以是任何字符。对此合适的正则表达式是什么？

最佳答案

使用捕获组：

var str = 'ersion: V3  Subject: EMAILADDRESS=[e-mail], GIVENNAME=Blob, SURNAME=Bloby, CN=B dddddddddddd, O=sd, C=IR  Signature Algorithm: SHA1withRSA, OID = 1.2.840.113549.1.1.5  Key:  Sun RSA public key, 2048 bits  modulus'
str.match(/EMAILADDRESS=([^,]+)/i)[1]
// => "[e-mail]"

[^,]匹配任何字符异常,。
