javascript - 正则表达式 - 不包含字符串且不以/结尾

Question

如何创建不包含字符串“umbraco”且不以/结尾的正则表达式

这是我目前所拥有的，但我无法使其完全正常工作，我们将不胜感激。

(?!umbraco)(?![/]$)

测试字符串是:

• > http://www.domain.com/umbraco/login.aspx - 不应该匹配
• > http://www.domain.com/pages/1/ - 不应该匹配
• > http://www.domain.com/pages/1 - 应该匹配

Answer 1

应该是这个正则表达式:

^(?!.*?umbraco).*?[^\/]$

解释:

^ assert position at start of a line
(?!.*?umbraco) Negative Lookahead - Assert that it is impossible to match the regex below
.*? matches any character (except newline)
Quantifier: Between zero and unlimited times, as few times as possible, expanding as needed
umbraco matches the characters umbraco literally (case sensitive)
.*? matches any character (except newline)
Quantifier: Between zero and unlimited times, as few times as possible, expanding as needed
[^\/] match a single character not present in the list below
\/ matches the character / literally
$ assert position at end of a line
