Example: creating a basic menu item

tinymce.init({
  selector: 'textarea',
  menu: {
    custom: { title: 'Custom Menu', items: 'undo redo basicitem' }
  },
  menubar: 'file edit custom',

  setup: (editor) => {
    editor.ui.registry.addMenuItem('basicitem', {
      text: 'My basic menu item',
      onAction: () => alert('Menu item clicked')
    });
  }
});

Using onSetup

onSetup is a complex property. It takes a function that is passed the component’s API and should return a callback that is passed the component’s API and returns nothing. This occurs because onSetup runs whenever the component is rendered, and the returned callback is executed when the component is destroyed. This is essentially an onTeardown handler, and can be used to unbind events and callbacks.

To clarify, in code onSetup may look like this:

onSetup: (api) => {
  // Do something here on component render, like set component properties or bind an event listener

  return (api) => {
    // Do something here on teardown, like unbind an event listener
  };
};

To bind a callback function to an editor event use editor.on(eventName, callback). To unbind an event listener use editor.off(eventName, callback). Any event listeners should be unbound in the teardown callback. The only editor event which does not need to be unbound is init e.g. editor.on('init', callback).

  • The callback function for editor.off() should be the same function passed to editor.on(). For example, if a editorEventCallback function is bound to the NodeChange event when the button is created, onSetup should return (api) => editor.off('NodeChange', editorEventCallback).

  • If onSetup does not have any event listeners or only listens to the init event, onSetup can return an empty function e.g. return () => {};.
