Tell us what’s happening:
Does anyone know what to do?
Should I use “componentDidMount()”?
Because on first mount, the P element should be empty, but when the button is clicked and the input is filled, the P element have to render a random answer…
So, when I have to use “componentDidMount()” , then not in the P element… Isn’t it?
Your code so far
const inputStyle = {
width: 235,
margin: 5
}
class MagicEightBall extends React.Component {
constructor(props) {
super(props);
this.state = {
userInput: '',
randomIndex: ''
}
this.ask = this.ask.bind(this);
this.handleChange = this.handleChange.bind(this);
}
ask() {
if (this.state.userInput) {
this.setState({
randomIndex: Math.floor(Math.random() * 20),
userInput: ''
});
}
}
handleChange(event) {
this.setState({
userInput: event.target.value
});
}
render() {
const possibleAnswers = [
'It is certain',
'It is decidedly so',
'Without a doubt',
'Yes, definitely',
'You may rely on it',
'As I see it, yes',
'Outlook good',
'Yes',
'Signs point to yes',
'Reply hazy try again',
'Ask again later',
'Better not tell you now',
'Cannot predict now',
'Concentrate and ask again',
'Don\'t count on it',
'My reply is no',
'My sources say no',
'Most likely',
'Outlook not so good',
'Very doubtful'
];
const answer = possibleAnswers // << change code here
return (
<div>
<input
type="text"
value={this.state.userInput}
onChange={this.handleChange}
style={inputStyle} /><br />
<button onClick={this.ask}>
Ask the Magic Eight Ball!
</button><br />
<h3>Answer:</h3>
<p>
{ /* change code below this line */ }
{ /* change code above this line */ }
</p>
</div>
);
}
};
