When Read more / Read less button is clicked, the DOM is modified to add or remove content so Drupal behaviours should be triggered.
1. Add HTML to a field which uses the renderer provided by this module, long enough for a part of it to be initially hidden.
2. In a custom module add a Drupal behaviour in a Javascript file:
(function ($) {
'use strict';
Drupal.behaviors.expandCollapseFormatterTest = {
attach: function () {
$('a').once().click(function () {
alert('Button was clicked !');
});
}
};
})(jQuery);3. If you placed links in the initially hidden part, the click event handler won't be added to that specific element because when behaviour is processed the link is not yet in the DOM.
Add Drupal.attachBehaviors(); in a correct place in expand_collapse_formatter.js
