Rendering a Bootstrap Component Using JSX - reactjs

Question

Editing for clarity: I cannot figure out how to dynamically create Boostrap Components using JSX in a react app. End goal is to get the new button in the "newBtnSpace" div when the first button is clicked. I have tried using show.hide methods, but those need to be hard coded. Trying to create buttons based off an array. code:
./components/newBSBtnSpaceFunc.js
import React, { Component } from 'react'
import { Button } from 'reactstrap'
export default function NewBSBtnFunc() {
let BtnArray = ["red", "blue", "green"].map((btn) => {
return React.createElement(
Button,
{variant: 'primary'},
'New Button',
{id: "newBtn"},
btn
)
}
./components/BSBtn.js
import React, { Component } from 'react'
import { Button } from 'reactstrap'
import NewBSBtnFunc from "./NewBSBtnFunc"
export default class BSBtn extends Component {
render() {
return (
<div>
<Button onClick={NewBSBtnFunc}>Click Me</Button>
<div id="newBtnSpace"></div>
</div>
)
}
}
App.js
import React from 'react';
import 'bootstrap/dist/css/bootstrap.min.css';
import BSBtn from "./components/BSBtn"
function App() {
return (
<div>
<BSBtn></BSBtn>
</div>
);
}
export default App;

Answer 1

You can conditionally show the new button by setting a state item (in this case showNewButton) to true in the onClick of the original button.
render() {
return (
<div>
<Button onClick={() => this.setState({ showNewButton: true }))}>Click Me</Button>
<div id="newBtnSpace">{ this.state.showNewButton && <Button variant="primary" id="newBtn">New Button</Button> }</div>
</div>
)
}
PS you've already successfully worked out how to create Bootstrap buttons in jsx:
<Button onClick={NewBSBtnFunc}>Click Me</Button>

Answer 2

onClick does not expect a return value so returning the new button won't do anything.
The way you have things organized makes it very difficult since you can't return anything from the function, and you can't modify state from outside the class. I would suggest moving your click handler into the component and using to to modify a state value that will show the second button.
Here is my suggestion:
import React, { Component } from 'react'
import { Button } from 'reactstrap'
export default class BSBtn extends Component {
state = {show: false}
handleClick = () => {
this.setState({ show: !this.state.show })
}
render() {
return (
<div>
<Button onClick={this.handleClick}>Click Me</Button>
<div id="newBtnSpace">
{this.state.show ?
<Button variant="primary" id="newBtn">New Button</Button>
: null}
</div>
</div>
)
}
}
Updated solution to your updated question:
class BSBtn extends React.Component {
state = {
show: false,
buttons: []
}
handleClick = () => {
this.setState({ show: !this.state.show })
}
handleAdd = () => {
this.setState({ buttons: [...this.state.buttons, (this.state.buttons.length + 1)] })
}
render() {
return (
<div>
<h3>Option 1</h3>
<button onClick={this.handleClick}>Click Me</button>
<div id="newBtnSpace">
{this.state.show ? [1,2,3].map((value) => (
<div>
<button>Button {value}</button>
</div>
))
: null}
</div>
<hr/>
<div style={{ marginTop: '30px' }}>
<h3>Option 2</h3>
<button onClick={this.handleAdd}>Click Me</button>
{this.state.buttons.map((value) => (
<div>
<button>Button {value}</button>
</div>
))}
</div>
</div>
)
}
}
ReactDOM.render(<BSBtn />, document.getElementById('root'))
