Tell us what’s happening:
I am displaying <ul></ul> elements still it is giving this error
The DisplayMessages component should render an h2, input, button, and ul element.
Your code so far
// Redux Code:
const ADD = 'ADD';
const addMessage = (message) => {
return {
type: ADD,
message
}
};
const messageReducer = (state = [], action) => {
switch (action.type) {
case ADD:
return [
...state,
action.message
];
default:
return state;
}
};
const store = Redux.createStore(messageReducer);
// React Code:
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);
}
handleChange(event) {
this.setState({
input: event.target.value
});
}
submitMessage() {
const currentMessage = this.state.input;
this.setState({
input: '',
messages: this.state.messages.concat(currentMessage)
});
}
render() {
return (
<div>
<h2>Type in a new Message:</h2>
<input
value={this.state.input}
onChange={this.handleChange}/><br/>
<button onClick={this.submitMessage}>Submit</button>
<ul>
{this.state.messages.map( (message, idx) => {
return (
<li key={idx}>{message}</li>
)
})
}
</ul>
</div>
);
}
};
class AppWrapper extends React.Component {
// render the Provider here
constructor(props){
super(props);
}
render(){
const Provider = ReactRedux.Provider;
return(
<div>
<Provider store={store}>
<DisplayMessages />
</Provider>
</div>
);
}
// change code above this line
};
