useEffect()在分页时多次重新呈现

import React, { useState, useEffect } from 'react';

const PaginationComponent = () => {
  const [currentPage, setCurrentPage] = useState(1);
  const [data, setData] = useState([]);

  useEffect(() => {
    // 模拟数据获取
    const fetchData = async () => {
      const response = await fetch(`https://api.example.com/data?page=${currentPage}`);
      const result = await response.json();
      setData(result);
    };

    fetchData();
  }, [currentPage]); // 仅在 currentPage 变化时重新执行 effect

  const handlePageChange = (newPage) => {
    setCurrentPage(newPage);
  };

  return (
    <div>
      <ul>
        {data.map(item => (
          <li key={item.id}>{item.name}</li>
        ))}
      </ul>
      <button onClick={() => handlePageChange(currentPage - 1)} disabled={currentPage === 1}>Previous</button>
      <button onClick={() => handlePageChange(currentPage + 1)}>Next</button>
    </div>
  );
};

export default PaginationComponent;
