    Default How to restrict a user to type only certain characters in the text field

    How to restrict a user to type only certain characters in the text field


    Hi,
    I need a text field where a user can type only certain characters like number field does where user can enter only numbers and dot.
    I tried with setting the regex for the text field but it allows user to type other characters and on blur it shows validation message. But I don't even want to allow the user to put other characters in it.
    Is there any way to get this?

    Any help will be appreciated.

    -Nitin

    Take a look at the numberfield sources how it is archieved there.

    Basicly it listens for the keypress event, checks the key and if it is a not allowed one, you have to prevent the default action.

    Default NumericField

    NumericField


    If you only want to receive number value, why not using NumericField.

    Only maybe you add a Listener to your TextField, and do some logic code to meet your requriements!
