Textbox.io 2.x Documentation : editor.events.focus.addListener()

Add a custom event listener to a Textbox.io editor focus event with editor.events.focus.addlistener().

You can detect that an editor has received focus by attaching a callback function to the editor’s focus event.

Example

editor.events.loaded.addListener(callback)

// Add a custom event listener to the editor focus event
editor.events.focus.addListener(function() {
        alert('Editor got focus.');
    });
};

callback Function Function executed when the editor receives focus.

No return value.
