Tell us what’s happening:
It doesn’t work for some reason?
Your code so far
class DisplayMessages extends React.Component {
constructor(props) {
super(props);
this.state = {
input: '',
messages: []
}
this.handleChange = this.handleChange.bind(this);
this.submitMessage = this.submitMessage.bind(this);
}
// Add handleChange() and submitMessage() methods here
handleChange(event) {
this.setState(state => ({
input: event.target.value,
}))
}
submitMessage() {
this.setState(state => ({
messages: state.messages.concat(state.input),
input: ""
}));
}
render() {
var li = this.state.messages.map((message, i) => (
<li key={i}>{message}</li>
))
return (
<div>
<h2>Type in a new Message:</h2>
{ /* Render an input, button, and ul below this line */ }
<input onChange={this.handleChange} value={this.state.input}/>
<button onClick={this.submitMessage}>Add message</button>
<ul>
{li}
</ul>
{ /* Change code above this line */ }
</div>
);
}
};
