Validators

Error messages

All validators have the possibility to customize their error message.
For example if you add the required validator and you want to set the error message "This field is absolutely required!".

"+validators" : 
{
   "required" : {"message" : 'This field is absolutely required!'}
}

Note: for some validators it is also possible to use some {0}, {1} arguments to show a configured value of the control.
