Load a react component on button onClick

I have the following code for a button in my ReactApp to open a new window with specific size:
<button
type="button"
style={{ height: '20px', width: '50px' }}
className="btn btn-primary"
onClick={() => {
window.open(
"",
"Popup",
"width=975, height=92, top=30"
);
}}
/>
I want to load another component when user clicks on the button. How can I achieve that? I have tried to load the component and then use it like the following, but didn't work:
import component from "./component"
<button
type="button"
style={{ height: '20px', width: '50px' }}
className="btn btn-primary"
onClick={() => {
window.open(
"{<component />}",
"Popup",
"width=975, height=92, top=30"
);
}}
/>
What would be the best way to do this?
Here is my component:
export default function component(props) {
return (
<div className="container">
<div className="cabinet"><img src={image} />
<div className="devices"> <img src={image2} />
</div>
</div>
);
}

Add a state in main page and pass it to component
const [open, setOpen] = useState[false];
const onClickHandle = () => {
setOpen(true);
};
return (
<>
<button
type="button"
style={{ height: '20px', width: '50px' }}
className="btn btn-primary"
onClick={onClickHandle}
/>
<component open={open} />
</>
);
Add a new props to control the component
export default function component(props) {
const { open } = props;
return (
<>
{open && (
<div className="container">
<div className="cabinet">
<img src={image} />
<div className="devices">
{' '}
<img src={image2} />
</div>
</div>
</div>
)}
</>
);
}

Using state hooks and conditional rendering, you can load a react component on a button onClick.
const [visible, setVisible] = React.useState(false);
function click(e) {
e.preventDefault();
setVisible(true);
}
return (
<div>
<button onClick={(event) => {
click(event)
}} />
{isVisible && (
<YourComponent />
)
}
</div>
)

Select only a card at a time on click in reactjs

I have a react component which has some cards, When I click the plus icon in the card, it would expand and show some data for 30sec and then the data will disappear and on click it will reappear again, here is the component
import React from "react";
import { FaPlus } from "react-icons/fa";
import useTimeout from "../../../common/useTimeout";
import { Modal } from "../../../common/Modal";
import { ToggleState } from "../../../common/Toggle";
import { BsSearch } from "react-icons/bs";
import AdvancedFilter from "./AdvancedFilter";
export default function CitiesList({ cities }: { cities: any }): JSX.Element {
const [filter, setFilter] = React.useState("");
const [sortType, setSortType] = React.useState("");
const [selectedCity, setSelectedCity] = React.useState<any | null>(null);
console.log(filter);
const sorted = cities.sort((a: { name: string }, b: { name: any }) => {
const isReversed = sortType === "asc" ? 1 : -1;
return isReversed * a.name.localeCompare(b.name);
});
const onSort = (sortType: React.SetStateAction<string>) => {
console.log("changed");
setSortType(sortType);
};
const [showMeta, setShowMeta] = React.useState(false);
const handleClick = () => setShowMeta(true);
const getSelectedCity = (selectedCity: any) => {
setSelectedCity(selectedCity);
console.log("SELECTED CITY", selectedCity);
};
const [visible, setVisible] = React.useState(true);
const hide = () => setVisible(false);
useTimeout(hide, 30000);
console.log("CITIES", cities);
console.log({ selectedCity });

}
here is the useTimeout function
import { useEffect, useRef } from "react";
function useTimeout(callback: () => void, delay: number | null) {
const savedCallback = useRef(callback);
useEffect(() => {
savedCallback.current = callback;
}, [callback]);
useEffect(() => {
if (delay === null) {
return;
}
const id = setTimeout(() => savedCallback.current(), delay);
return () => clearTimeout(id);
}, [delay]);
}
export default useTimeout;
Now currently if I click on one card, all the cards opens and also after when the data disappears after 30sec it does not reappear on button click. I need to reload the page to do reappear data again.I need to solve 2 issues here: 1. how can I open one card only at a time on clicking on the icon, 2. how can I reappear data on button click without refreshing the page.

As I understand you, some information is
<p>Longitude: {item.longitude}</p>
<p>Latitude: {item.latitude}</p>
<p>Population: {item.population}</p>
You have global statement of showing this info for all cards. To reduce it, make new component which will have local state of this info:
import React from 'react'
const timeout = 15000
export const CityCard = ({item, visible, getSelectedCity}) => {
const [showMeta, setShowMeta] = React.useState(false)
const handleClick = React.useCallback(()=>{
setShowMeta(true)
setTimeout(()=>{
setShowMeta(false)
},timeout )
}, [showMeta])
return(
<div className="col-lg-3" key={index}>
<div
className="card"
style={{
textAlign: "center",
display: "flex",
justifyContent: "center",
paddingBottom: "1rem",
marginBottom: "1rem",
marginRight: "1rem",
}}
>
<div className="card-body">
<h5 className="card-title">{item.name}</h5>
</div>
{visible && showMeta ? (
<div>
<p>Longitude: {item.longitude}</p>
<p>Latitude: {item.latitude}</p>
<p>Population: {item.population}</p>
{/* <p>Time Zone: America</p> */}
</div>
) : (
<button
onClick={() => {
handleClick();
getSelectedCity(item.id);
}}
type='button'
disabled={showMeta}
style={{ cursor: "pointer" }}
>
<FaPlus size="18" />
</button>
)}
</div>
</div>
)
}
At the end, add this component to the CityList

How can i use useParams() with an onClick button to navigate to different pages and display the data in react.js?

I'm working on a billing app. I have managed to fetch the Products from an API..... But now I'm trying to use useParams() to navigate to random pages that would display the items according to the ID by pressing a button...the navigation works fine but it wont display the data of that passed ID, it displays all the data in my API.
I would really appreciate some help or feedback, Thanks !

The ":" of path="/bills/:id" is only used to designate id as a route parameter, it isn't meant to be part of any URL. When you link to to={`/bills/:${items.id}`} you are adding ":" to the id string value.
Remove it from the link. You should also ensure that the Items component has items to map, where each specific item mapped renders the link/button to link to the appropriate bill list page.
<Link to={`/bills/${item.id}`}>
<button className="button4">Analyse Receipt</button>
</Link>
The Items route also doesn't specify any route params, so there will be be none in the `Items component.
<Route exact path="/" component={Items} />

First modal on each page not displaying data

I am making a workstation assessment website.
I am stuck with an issue I am having.
The modal is my a grandchild component (modal complete questions). I then have a component named questions as a parent and as the parent to that I have Admin Workstations.
Hierachy
1.AdminWorkstations,
2.Questions,
3.Modal,
(this is not full functionality of these components but is just for the use case I am asking for).
1.Parent gets WSAId(just a id).Passes down to questions.
2.Questions passes the modal component this.
3.Modal gets questions using this id.
However the first modal does not display.I have paginated the results of these page if this makes any diffrence.
this is my modal
import "./ViewWorkstationModal.css";
import React, { useState, useEffect } from "react";
import { Modal, DropdownButton, Dropdown } from "react-bootstrap";
function ModalCompletedQuestions(props) {
const [show, setShowState] = useState(0);
const [loadingToken, setLoadingToken] = useState(0);
const [answeredQuestions, setAnsweredQuestions] = useState([{}]);
useEffect(() => {
setLoadingToken(true);
let data = {
WSAId: props.WSAId
};
fetch("/get-completed-questions", {
method: "POST",
headers: {
Accept: "application/json",
"Content-Type": "application/json"
},
body: JSON.stringify(data)
})
.then(recordset => recordset.json())
.then(results => {
setAnsweredQuestions(results.recordset);
});
}, []);

setShowState(false);

How come when the first is clicked the modal appears blank but the rest of the modals are filled with the right data.
Essentially it seems as if though the first modal is not performing the data fetch which is within the modal component.
Any extra information needed let me know but these seem to be the most important for this use case.
Any help is much appreciated.

I completed this by using a condition within the use effect.
useEffect(() => {
setLoadingToken(true);
let data = {
WSAId: props.WSAId
};
fetch("/get-completed-questions", {
method: "POST",
headers: {
Accept: "application/json",
"Content-Type": "application/json"
},
body: JSON.stringify(data)
})
.then(recordset => recordset.json())
.then(results => {
setAnsweredQuestions(results.recordset);
});
}, [PUT YOUR CONDTION HERE]);
I simply just passed my props through so it says every time there is a new props do this.

Re-render the same component with different parameter

I am working on a react project with similar functionality to a social media site. I have a user profile component below that has links to other user profiles(towards bottom of code below) that are being followed by the current user. Essentially what I am trying to do is re-render the same component with a different user. However, the link to the new user profile doesn't result in the getProfile action getting called so the redux state doesn't update. How can I navigate to the new profile and have the useEffect hook get called again with the new username?
Thank You!

You need to track userAlias in the useEffect's dependencies list, the api callback will be called each time it changes.

useEffect(() => {
getProfile(userAlias);
