Sometimes, you work with forms with checkboxes fields in react js app. And at that time, you want to get all checked checkbox values on submitting in react js app.

So, let's see how to get checkbox values in react js or react js to get multiple checkbox values.

 

In this step, we will create a new react app.

npx create-react-app my-react-app

 

To run the React app, execute the following command on your terminal.

npm start

 

 

In this step, we will install the bootstrap 4 libraries into your react app.

npm install bootstrap --save

Add the bootstrap.min.css file to src/App.js the file.

import React from 'react';
import '../node_modules/bootstrap/dist/css/bootstrap.min.css';
 
function App() {
  return (
    <div>
      <!-- Code here -->
    </div>
  );
}
 
export default App;

 

In this step, we will create a checkbox form component named CheckboxForm.js.

import React from 'react'
class CheckboxForm extends React.Component{

constructor(){
	super();
	this.state = {
		hobbies:[]
	}
	this.handleInputChange = this.handleInputChange.bind(this);
}

handleInputChange(event) {
	const target = event.target;
	var value = target.value;
	if(target.checked){
		this.state.hobbies[value] = value;   
	}else{
		this.state.hobbies.splice(value, 1);
	}
}

submit(){
	console.warn(this.state)
}

render(){
	return(
	<div>
		<div class="row">
			<div class="col-md-6 offset-md-3">
				<br /><br />
				<h3>How To Get Multiple Checkbox Value In React JS - Websolutionstuff</h3><br />
				<div class="form-row">
					<div class="form-group col-md-6">
						<label>Hobbies :</label><br />
						<div class="form-check form-check-inline">
						<input class="form-check-input" type="checkbox" name="hobbies" id="inlineCheckboxh1" value="1" onChange={this.handleInputChange} />
						<label class="form-check-label" for="inlineCheckboxh1">Cricket</label>
					</div>
					<div class="form-check form-check-inline">
						<input class="form-check-input" type="checkbox" name="hobbies" id="inlineCheckboxh2" value="2" onChange={this.handleInputChange} />
						<label class="form-check-label" for="inlineCheckboxh2">Reading</label>
					</div>
					<div class="form-check form-check-inline">
						<input class="form-check-input" type="checkbox" name="hobbies" id="inlineCheckboxh3" value="3" onChange={this.handleInputChange} />
						<label class="form-check-label" for="inlineCheckboxh3">Cooking</label>
					</div>
				</div>
			</div>
			<div class="form-row">
				<div class="col-md-12 text-center">
					<button type="submit" class="btn btn-primary" onClick={()=>this.submit()}>Submit</button>
				</div>
			</div>
		</div>
	</div>
	</div>
	)  
	}
}
export default CheckboxForm;

 

 

In this step, we need to add the CheckboxForm.js file in src/App.js file:

import React from 'react';
import '../node_modules/bootstrap/dist/css/bootstrap.min.css';
import CheckboxForm from './CheckboxForm'
function App() {  
return (  
<div className="App">  
<CheckboxForm/>  
</div>  
);  
}  
export default App;
