I need to add a custom javascript to the Quiz Question Multichoice form through a custom module, but adding my library to $form['#attached']['library'] won't work.
Create a custom module and in your .module, add a function that implements the hook_form_FORM_ID_alter for quiz_question_multichoice form.
function mymodule_form_quiz_question_multichoice_form_alter(&$form, FormStateInterface $form_state, $form_id) {
$form['#attached']['library'][] = 'mymodule/multichoice';
}
In the .libraries.yml add the "multichoice" section with the reference to a JS (and/or CSS):
multichoice:
js:
js/multichoice.js: {}
dependencies:
- core/drupalSettings
- core/jQuery
Activate the module, edit an existing question or add a new one.
The library won't load.
Maybe this won't apply to many, because of the module priority. This happens only if the custom module runs before than quiz_multichoice.
In quiz_multichoice.module, function quiz_multichoice_form_quiz_question_multichoice_form_alter, the 'library' array item is set overwriting any previous value:
$form['#attached']['library'] = ['quiz_multichoice/helper'];
Adding the library to existent ones should solve:
$form['#attached']['library'][] = 'quiz_multichoice/helper';
Attaching patch.
