Is there "rejected" kind of event?

[uhfath]

When a user types something that is not accepted by the mask it would be a nice UX to inform that it's an invalid input (with some hint under control).
Is anything like this currently possible?
There are accept and complete events but no reject or something like that.
For example, if we have a mask for a phone number, when a user presses a letter key the input element will not react and in this case I wanted to show some hint that the key he pressed is not supported in this field.
