Regular expresion with RegExp or maybe an other lib?

[sitajony]

Hi, today I would know how know if there're only letters or/and number on a string and not others characteres...

I used [a-z0-9] but of course it return Match if there're a letter/number and also when there're a sign (/"-+('-)...

Thanks for your help!

The RegEx library fully supports the Regular Expressions syntax. If you are struggling a little bit; please post some example strings of what should and should not match.

Thanks but I found in fact I can search if there're any symbol and if yes so there aren't only letters/numbers...
I was not in the good way
