What’s wrong with my code? The result is exactlt the same as what expected, but it doesn’t pass. Or the section is problematic?
**Your code so far**
class DisplayMessages extends React.Component {
constructor(props) {
super(props);
this.state = {
input: '',
messages: []
}
}
// Add handleChange() and submitMessage() methods here
handleChange=(event)=>{
const {input, messages}=this.state;
this.setState({input:event.target.value, messages:[...messages]})
}
submitMessage=()=>{
let inputBox=document.querySelector('#input');
const {input, messages}=this.state;
if(input.trim()===''){
alert('You typed in nothing!')
} else {
this.setState({input:'', messages:[...messages,input]});
}
inputBox.value='';
}
render() {
return (
<div>
<h2>Type in a new Message:</h2>
{ /* Render an input, button, and ul below this line */ }
<input id='input' type='text' onChange={this.handleChange}/>
<button onClick={this.submitMessage}>Add message</button>
<ul>
{
this.state.messages.map(message=>{
return <li>{message}</li>
})
}
</ul>
<h3>{this.state.input}</h3>
{ /* Change code above this line */ }
</div>
);
}
};
