I am new to React and was learning how to handle multiple inputs in form. Here is the code :
class Login extends Component {
constructor () {
super();
this.state = {
email: '',
password: ''
};
this.handleChange = this.handleChange.bind(this);
}
handleChange (evt) {
// check it out: we get the evt.target.name (which will be either email or password)
// and use it to target the key on our `state` object with the same name, using bracket syntax
this.setState({ [evt.target.name]: evt.target.value });
}
render () {
return (
<form>
<label>Email</label>
<input type=text name=email onChange={this.handleChange} />
<label>Password</label>
<input type=password name=password onChange={this.handleChange} />
</form>
);
}
}
The question is how can this.setState({ [evt.target.name]: evt.target.value }); replace several handlers? Does [evt.target.name] represent both inputs?
