Yesterday I wrote validation (C# and regular expressions) and today I wrote a js version of validation. Now post out, in order to facilitate their own access, but also hope to give people in need of help and some inspiration. As I just started to contact JS today, there may be some mistakes and omissions, I hope you can criticize and correct.
