RegExp Question -> Max/Min Length

Hello Support,

does dhtmlxForm supports following expressions: ^[a-zA-Z0-9]{1,3}$ ?
I am interested on limitations {x,y}. Do I need to mask the braces or something else?

Thank you for your help!

There is a ready property maxLength.
About min - you can use any custom validate function for checking and forbid lack of symbols.

My wish was to work with regExpressions only, but this is a solution too. Thank you very much, Darya.

You are welcome!
