BX.PhoneNumber is undefined?

Question

1C-Bitrix

When calling "BX.validation.checkIfPhone(phone);" the following error occurs:

TypeError: BX.PhoneNumber is undefined

Perhaps something is not connected?

Answer 1

I didn’t check it myself, but if you google BX.PhoneNumber there will be a link but docks, connect the library
CJSCore::Init(['phone_number']);
