使用RegEx排除某些字符

Question

Try as I might, I can't get a RegEx to exclude space or single quotes.

• The string "abc" is allowed
• Not allowed: "a'bc", "'", "'abc", "'''", "abc''" etc
• Spaces could replace the ' too in the above example
• Trailing and leading spaces are assumed to be removed already
• Empty strings are checked elsewhere
• Target language is javascript

I'd use PATINDEX if I was in SQL.

Or NOT a positive match on either space or single quote, if I could negate...

I've tried (for single quote only)

• \\w*[^']\\w*
• ^\\w*[^']\\w*$
• others I forget now

Please put me out of my misery so I can sleep tonight.

Edit:

• Target string will not be surrounded by Quotes. I thought thy might add clarity
• If "Target language is javascript" is wrong, then it's c#. I'd have to check where we do the validation exactly: client javascript or server c#

Answer 1

^[^\'\ ]*$

?

Answer 2

Quite simple. Does not allow empty strings.

^[^' ]+$

Answer 3

i think this

^\w*$

should work as \\w does not include single quote or space.

Answer 4

没有阅读细节，我在那里看不到[^']（有空格和单引号）。
