-
-*1: `ElementInternals.states`, i.e. `CustomStateSet`, is not implemented in jsdom, so you need to apply a patch in the custom element constructor.
-
-``` javascript
-class LabeledCheckbox extends window.HTMLElement {
- #internals;
- constructor() {
- super();
- this.#internals = this.attachInternals();
- // patch CustomStateSet
- if (!this.#internals.states) {
- this.#internals.states = new Set();
- }
- this.addEventListener('click', this._onClick.bind(this));
- }
- get checked() {
- return this.#internals.states.has('checked');
- }
- set checked(flag) {
- if (flag) {
- this.#internals.states.add('checked');
- } else {
- this.#internals.states.delete('checked');
- }
- }
- _onClick(event) {
- this.checked = !this.checked;
- }
-}
-```
