react.js中如何实现对表中列表数据的分页？

Question

需要快速帮助！我有来自 API 的表格中呈现的数据列表。我需要将此数据列表分页为小数据列表。

这是 VendorsDetail.js 的代码，它在表格中显示数据列表

import React, { useState, useEffect } from "react";
import HelpOutlineIcon from "@mui/icons-material/HelpOutline";
import axios from "axios";
import VendorDetailsBrief from "./VendorDetailsBrief";
import Pagination from "./Pagination";

const VendersDetail = ({ textMe }) => {
  const [data, setData] = useState({});
  const foo = "cpe:2.3:a:oracle:peoplesoft_enterprise:8.22.14";
  const baseURL =
    "https://services.nvd.nist.gov/rest/json/cves/1.0?cpeMatchString=" + foo;

  useEffect(() => {
    axios
      .get(baseURL)
      .then((response) => {
        setData(response.data);
      })
      .then(
        (response) => {},
        (err) => {
          alert(err);
        }
      );
  }, []);

  const DisplayData = data?.result?.CVE_Items?.map((vender) => {
    return (
      <tr>
        <td className="color_id font-semibold">
          {vender?.cve?.CVE_data_meta?.ID}
        </td>
        <td className="w-96">
          {vender?.cve?.description?.description_data?.[0]?.value}
        </td>
        <td>{vender?.impact?.baseMetricV2?.exploitabilityScore}</td>
        <td>{vender?.impact?.baseMetricV2?.severity}</td>
        <td>{vender?.impact?.baseMetricV2?.impactScore}</td>
      </tr>
    );
  });
  return (
    <div className="z-100 flex justify-center items-center mt-10">
      <div className="text-black">
        <div className="rounded overflow-hidden flex  justify-center items-center">
          <table class="table table-striped ">
            <thead>
              <tr>
                <th>Vuln ID</th>
                <th>Description Data</th>
                <th>Exploitability Score</th>
                <th>Severity</th>
                <th>Impact Score</th>
              </tr>
            </thead>
            <tbody>{DisplayData}</tbody>
          </table>
        </div>
      </div>
    </div>
  );
};

export default VendersDetail;

Pagination.js

从“反应”导入反应；

const Pagination = ({ postsPerPage, totalPosts, paginate }) => {
  const pageNumbers = [];

  for (let i = 1; i <= Math.ceil(totalPosts / postsPerPage); i++) {
    pageNumbers.push(i);
  }

  return (
    <nav>
      <ul className="pagination">
        {pageNumbers.map((number) => (
          <li key={number} className="page-item">
            <a onClick={() => paginate(number)} href="!#" className="page-link">
              {number}
            </a>
          </li>
        ))}
      </ul>
    </nav>
  );
};

export default Pagination;

如何在这个特定的数据列表中实现分页？谢谢

Answer 1

1. 使用逻辑创建父组件以从 URL 和分页 onCLick 处理程序获取数据。

2. 父组件应该渲染 VendorsDetail 组件和 Pagination 组件。

3. 将要显示的数据传递给 VendorsDetails 组件，并将 getSubsequentData 处理程序传递给 Pagination 组件。

4. 如果用户点击特定页码，调用 getSubsequentData 处理程序并使用特定参数，更新父组件的状态，这将更新 VendorsDetail 组件。

   const ParentComponent = () => {

    const [data, setData] = useState({})
   
    useEffect = (() => {
      // axios call to get initial data from the URL
    })
   
    getSubsequentData = (URL) => {
      // axios call to get data based on the URL.
      // LInk this to pagination onClick
    }
          return(
    <VendorsDetail data={data} />
    <Pagination getNextData={getSubsequentData}/>
   

   ) }
