The program does exactly what it’s supposed to do, and the syntax seems to match all the examples I’ve found online, yet for some reason, the third text gives me a ‘Cannot read property ‘target’ of undefined’ error. What am I missing here?
Your code so far
class ControlledInput extends React.Component {
constructor(props) {
super(props);
this.state = {
input: ''
};
// change code below this line
this.handleChange = this.handleChange.bind(this);
// change code above this line
}
// change code below this line
handleChange() {
this.setState ({
input: event.target.value});
}
// change code above this line
render() {
return (
<div>
{ /* change code below this line */}
<input type = "text" value = {this.state.input} onChange = {this.handleChange} />
{ /* change code above this line */}
<h4>Controlled Input:</h4>
<p>{this.state.input}</p>
</div>
);
}
};
