beforeInputUpdate

Options

Executes the callback function before an input is about to be updated. This allows you to intercept and potentially modify input changes before they are applied.

let keyboard = new SimpleKeyboard({
  beforeInputUpdate: (instance) => {
    console.log('About to update input');
    console.log('Current input:', instance.getInput());
    
    // You can perform validation or modifications here
    // before the input is actually updated
  }
});

// This callback is triggered before any input change
// giving you a chance to validate or modify the update
