Client-side Form Validation
- Check inputs before sending them to the server.
- event.stop()
- Convenience function on event data object
- Same as doing both:
- event.stopPropagation();
- event.preventDefault();
- Example 1
Client-side Form Processing
- Form information only being used on client-side
- More common these days with AJAX based interfaces
- Two ways:
- Process form 'submit' event.
- Process 'click' event on submit button.
- Either case:
- Need to call event.stop() to prevent form from going to server-side.
