Changelog

Add a validateElement option to ValueMissingValidator for cases where valueMissing (required) isn’t keyed off of element.value such as checkboxes #7

v0.0.10

Introduce a pattern for easier translations of error messages
Fixed checks to make sure this.internals and superclass.formAssociated aren’t already defined.

BREAKING_CHANGE: Validators are now functions. Because of shared objects, we don’t want mutations to override objects. This also opens up the possibility of allowing “options” in the future.
Feature: this.updateInteractionState() is now exposed on the host element.
Feature: this.updateValidity() is now exposed on elements and replaces the old private runValidators(element) function.
Feature: Added CustomStatesMixin to allow setting custom states even if the element is not formAssociated.
Bug: remove runValidators from formDisabledCallback.
Bug: Fixed a bug in tabindex detection in the constructor.
Bug(types): Loosened Lit version for types for better deduping.
Bug: Removed checkFocusability
Deprecated: No longer run validators prior to setFormValue
Deprecated: Remove set form(value: string) it’s confusing because browsers dont do this, and you should set the attribute manually.

Feature: Added the following functions for custom states to VanillaFormAssociatedMixin:

JavaScript

addCustomState (state) {}
deleteCustomState (state) {}
hasCustomState (state) {}
toggleCustomState (state, force) {}

With fallbacks for unsupported browsers.

Bug Fix: runValidators() now preserves custom errors, and will also run prior to checkValidity() and reportValidity().

validationTarget is defined as a getter and falls back to the value of this.formControl
