A default action is the browser behavior normally performed in response to an event when that behavior is not canceled.
- How it is used
- Handles browser behaviors that conflict with React interfaces, especially form submission and navigation.
- How deep it goes
- Explains browser defaults, React’s preventDefault() method, form-level handling, Enter-key submission, and cancellable-event limits.
- Examples
- Uses an admin login form, a button inside a form, link navigation, keyboard input, scrolling, and drag events.
- What you can do after
- Apply via React event handlers by moving submission logic to onSubmit and calling preventDefault() when cancellation is required.
