This is my Json file which I created in my app.
export const Data = [
{
id: 1,
title: "Tilte 1",
description: "Decription 1 Data",
},
{
id: 2,
title: "Tilte 2",
description: "Decription 2 Data",
}
];
This is my main file from where I navigate it. I use json file to display all the records on page. When I click on selected item it will get its id and navigate to another page, where i can get the data of selected item coming from json.
import React from "react";
import { Data } from "./JSON"
import { useNavigate } from 'react-router-dom'
const Home = () => {
let naviagte = useNavigate();
return (
<>
{Data.map((data, key) => {
return (
<div class="card" >
<div class="card-body">
<h5 class="card-title" key={key.id}>{data.title}</h5>
<p class="card-text">{data.description}</p>
<button onClick={() => naviagte(`/service/${data.id}`)}>{data.title} </button>
</div>
</div>
);
})}
</>
)
}
export default Home;
When I navigate to another page where I want to display all data regarding the selected id. It shows only id not all data.
import React, {useState, useEffect} from "react";
import { Data } from "../home/JSON"
import { useParams } from "react-router-dom";
const Service = () => {
const { id } = useParams();
const [data, setData] =useState('');
console.log("check", data);
useEffect(() => {
setData (Data.map((_data) => _data.id === id ))
}, [id])
return(
<>
{id}
{data.title}
{data.description}
</>
)
}
export default Service;
Please guide me what I miss here. Thanks in Advance
Since you are importing the data in both places you just need to find the data by the id property instead of mapping it to booleans. Keep in mind that your id property is a number but the id route param will be a string, so you will need to convert them to a compatible type for the strict equality (===) check.
Example:
useEffect(() => {
setData(Data.find((_data) => String(_data.id) === id));
}, [id]);
Since data is treated as an object in the render return you'll want to insure you maintain a valid state invariant. Update the initial data state to be an object, and check that Array.prototype.find returned a defined object from the Data array before updating state.
const Service = () => {
const { id } = useParams();
const [data, setData] = useState({});
console.log("check", data);
useEffect(() => {
const data = Data.find((_data) => String(_data.id) === id);
if (data) {
setData(data);
}
}, [id]);
return (
<>
{id}
{data.title}
{data.description}
</>
);
};
