Events Available for TinyMCE

TinyMCE supports some browser-native events, and provides additional events for working with the editor and plugins.

Handling Editor events

The following examples illustrate how to use supported native events, editor core events, and plugin events with TinyMCE.

The following example uses a function to create a console log entry when the editor has initialized. This is also an example of handling an event which does not return any data.

tinymce.init({
  selector: 'textarea',
  setup: (editor) => {
    editor.on('init', (e) => {
      console.log('The Editor has initialized.');
    });
  }
});

The following example uses a function to create a console log entry when a command is executed in the editor. This is also an example of handling an event that returns data.

tinymce.init({
  selector: 'textarea',
  init_instance_callback: (editor) => {
    editor.on('ExecCommand', (e) => {
      console.log(`The ${e.command} command was fired.`);
    });
  }
});
