React- Cannot read property 'setState' of undefined

Question

for some reason, I\'m getting the error \" React- Cannot read property \'setState\' of undefined\". So this.state is never getting updated with the values that the user inputs.

Answer 1

If you use an arrow function then you won't need to bind.

onNameChange = (e)=> {
this.setState({name:e.target.value});
}

onPasswordChange = (e) => {
this.setState({password:e.target.value});
}
