angular - Angular2 get existing validators of a formcontrol -


lets say

surname = new formcontrol('', [validators.required, validators.minlength(2)]);

at point depending on situation may add or delete validators on surname control.

something 

surname.getvalidators() should return - ['required', 'minlength']

reading validators control not supported

see https://github.com/angular/angular/issues/13461
