import '../node_modules/bootstrap/dist/css/bootstrap.min.css';
 
function App() {
  return (
    <div>
      <h2>How to Get Form Values On Submit in React JS</h2>
    </div>
  );
}
 
export default App;

In this step, we will visit the src directory of our React js app and create a form component named SimpleForm.js in which we have to add the below-given code:

import React from 'react'
class SimpleForm extends React.Component{
constructor(){
super();
this.state = {
first_name:null,
last_name:null,
email:null,
city:null,
address:null,
gender:null,
hobbies:[]
}
this.handleInputChange = this.handleInputChange.bind(this);
}
handleInputChange(event) {
const target = event.target;
var value = target.value;
const name = target.name;
if(target.type === 'checkbox'){
if(target.checked){
this.state.hobbies[value] = value;   
}else{
this.state.hobbies.splice(value, 1);
}
}else{
this.setState({
[name]: value
});
}   
}
submit(){
console.warn(this.state)
}
render(){
return(
<div>
<div class="row">
<div class="col-md-6 offset-md-3">
<br /><br />
<h3>Register Form</h3><br />
<form>
<div class="form-row">
<div class="form-group col-md-6">
<label>First Name :</label>
<input type="text" class="form-control" name="first_name" onChange={this.handleInputChange} />
</div>
<div class="form-group col-md-6">
<label>Last Name :</label>
<input type="text" class="form-control" name="last_name" onChange={this.handleInputChange} />
</div>
</div>
<div class="form-row">
<div class="form-group col-md-6">
<label>Email :</label>
<input type="email" class="form-control" name="email" onChange={this.handleInputChange} />
</div>
<div class="form-group col-md-6">

<select class="form-control" name="city" onChange={this.handleInputChange}>
<option selected>Select City</option>
<option value="1">city 1</option>
<option value="2">city 2</option>
<option value="3">city 3</option>
</select>
</div>
</div>
<div class="form-row">
<div class="form-group col-md-6">
<label>Gender :</label><br />
<div class="form-check form-check-inline">
<input class="form-check-input" type="radio" name="gender" id="inlineRadiom" value="male" checked={this.state.gender === "male"} onChange={this.handleInputChange} />
<label class="form-check-label" for="inlineRadiom">Male</label>
</div>
<div class="form-check form-check-inline">
<input class="form-check-input" type="radio" name="gender" id="inlineRadiof" value="female" checked={this.state.gender === "female"} onChange={this.handleInputChange} />
<label class="form-check-label" for="inlineRadiof">Female</label>
</div>
</div>
<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">Reading</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">Developing</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">Desiging</label>
</div>
</div>
</div>
<div class="form-row">
<div class="form-group col-md-12">
<label>Address :</label>
<textarea name="address" class="form-control" onChange={this.handleInputChange} />
</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>
</form>
</div>
</div>
</div>
)  
}
}
export default SimpleForm;

 

Step 4- Add Component In App.js

Here, we will be adding the SimpleForm.js file in the src/App.js file:

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