Accessing form values (React)

// InfoForm.js

this.state = {
  submitted: false,
  userEmail: '', // we'll start this off as an empty string
}; 

//We can attach the onChange listener to our <input> element. This will be triggered every time a change is made inside our input. For example, if the user enters the string, 'pillow' inside of our input, onChange() will fire 6 times, one for each character inside the string.

// InfoForm.js

<input onChange={this.handleChange} className="infoForm-input" type="email" placeholder="Enter your email here"/> 
  
//Finally, we'll need to create the handleChange() method itself:
  
// InfoForm.js

handleChange = (evt) => {
  this.setState({ userEmail: evt.target.value });
};
