const handleSubmit = (event) => { event.preventDefault(); fetch('/api/updateMovieRating', { method: 'PUT', headers: { 'Content-Type': 'application/json', }, body: JSON.stringify({ userId, movieId, rating }), }) .then((response) => response.json()) .then((data) => console.log(data)) .catch((error) => console.error('Error:', error)); };

return ( <form onSubmit={handleSubmit}> <input type="text" value={movieId} onChange={(e) => setMovieId(e.target.value)} placeholder="Movie ID" /> <input type="number" value={rating} onChange={handleRatingChange} placeholder="Rating" /> <button type="submit">Update Rating</button> </form> ); } This example provides a basic illustration. Depending on your specific requirements and technology stack, you'll need to adapt and expand upon this.
