我正在建立一个项目, 用户应该能够很容易地生成链接, 设置 : # # 这是链接 # 。 我正试图在 2 # 符号和正数之间抓住绳索。 我尝试过,

#.+#

如果用户字符串中只有1个链接,它就能完美运作,但如果有超过1个链接,例如,

#asdfasdf asdf# asdf asfasdfasdf asd fasd fasdf #asdfasdf asdfasdf asdf asdf#

但我需要他们分开,所以我可以用标签代替他们

最佳回答

这被称为“ greedy regex ” 。 默认的正则表达式符合最长的字符串 。 您可以使用这种方式使其不具有细化性 :

/#.+?#/

使用非细密匹配

#.+?#

它会捕捉到非视觉的
