Wie verwende ich mehrere React-Bootstrap-Muster?

Question

Ich habe ein React-Bootstrap-Modal, in dem ich meine Daten zuordne, aber das Problem ist, wenn ich auf das Modal klicke, zeigen alle Modalitäten die gleichen Daten an, es ist offensichtlich das letzte Element des Arrays in allen Modalitäten. Ich möchte Modalitäten dynamisch generieren und unterschiedliche Daten für verschiedene Modalitäten anzeigen.

const content: { cardimg: string, Name: string, Post: string, Nation: string, About: string, mod:string }[] = [
{
"cardimg": `hello`,
"Name": "someone 1",
"Post": "Chairman & CEO",
"Nation": "India",
"About": "holds a degree of Executive MBA in Entrepreneurship from Rennes School of Business, France.",
"mod": "one"
},
{
"cardimg": `world`,
"Name": "someone 2",
"Post": "Deputy CEO",
"Nation": "India",
"About": "holds a degree in MBA Finance, someone 2 has more than 7 years of experience in Customer Engagement Services.",
"mod": "two"
},

const Leadershipcard = (prop: props) =\> {

    const [modalShow, setModalShow] = useState(false)
    
    
    return (
        <>
            {content.map((e) =>
                <div className="card col-lg-6 p-0" style={{ "width": "18rem" } as React.CSSProperties}>
                    <img src={`Assets\About\team\${e.cardimg}.webp`} className="card-img-top" alt="..." />
                    <div className="card-body">
                        <h5 className="card-title">{e.Name}</h5>
                        <p className="card-text">{e.Post}</p>
                        <a href="/" className="d-block fs-4"><i className="fa-brands fa-linkedin-in"></i></a>
                        <button className="btn btn-outline-dark btn-dark rounded-0 text-bg-light mt-2 vi-more"
                            onClick={() => setModalShow(true)} data-bs-toggle="modal" data-bs-target={`/mod${e.mod}`}>View More</button>
                       ** <Modals
                            show={modalShow}
                            onHide={() => setModalShow(false)}
                            Img={e.cardimg}
                            Name={e.Name}
                            Post={e.Post}
                            Nation={e.Nation}
                            About={e.About}
                            mod={e.mod}
                        />**
                    </div>
                </div>
            )}
        </>
    )

}

模态状态必须维护在数组中以跟踪特定模态。

我们可以通过在打开和关闭模态时传递数组索引来实现。

import React, { useEffect, useState } from "react";
import { Button, Modal } from "react-bootstrap";

const Modals = ({ show, onHide, about, name }) => {
  return (
    
      
        {name}
      
      {about}
      
        
          Close
        
      
    
  );
};

const content = [
  {
    cardimg: `hello`,
    Name: "someone 1",
    Post: "Chairman & CEO",
    Nation: "India",
    About:
      "Holds a degree of Executive MBA in Entrepreneurship from Rennes School of Business, France.",
    mod: "one"
  },
  {
    cardimg: `world`,
    Name: "someone 2",
    Post: "Deputy CEO",
    Nation: "India",
    About:
      "Holds a degree in MBA Finance, someone 2 has more than 7 years of experience in Customer Engagement Services.",
    mod: "two"
  }
];

const LeadershipCard = (prop) => {
  const [modalShow, setModalShow] = useState([]);

  const handShow = (index) => {
    const modalStateClone = [...modalShow];
    modalStateClone[index] = true;
    setModalShow(modalStateClone);
  };

  const handleClose = (index) => {
    const modalStateClone = [...modalShow];
    modalStateClone[index] = false;
    setModalShow(modalStateClone);
  };

  useEffect(() => {
    if (content?.length > 0) {
      const contentArr = content.map((c) => {
        return false;
      });
      console.log(contentArr);
      setModalShow(contentArr);
    }
  }, []);

  return (
    
      {content.map((e, index) => (
        

          

            
{e.Name}
            
{e.Post}
            
              
            
             handShow(index)}
              data-bs-toggle="modal"
              data-bs-target={`/mod${e.mod}`}
            >
              View More
            
             handleClose(index)}
              img={e.cardimg}
              name={e.Name}
              post={e.Post}
              nation={e.Nation}
              about={e.About}
              mod={e.mod}
            />
          

        
      ))}
    >
  );
};

export default LeadershipCard;
