I need to match only a-z 0-9 and spaces between words and numbers. I try with [a-z0-9\s] but with this regex I match \n \t and \r.

I try with this: http://regexr.com?30rs7 but I don't know is this code work correctly and I ask about the correct regexp :)

Regards, George!

从字面上理解：

[a-z0-9 ]

空格而不是\s与您不想匹配的其他人匹配。

怎么样[a-z0-9 ]？

那应该这样做。

我在您的情况下使用的正则表达式是这样的：

[a-zA-Z0-9 ]
