を行うための適切な方法は何である私は、この試みた:
を210export function mapDispatchToProps(dispatch) {
return {
onChangeUsername: (evt) => dispatch(changeUsername(evt.target.value)),
onSubmitForm: (evt) => {
if (evt !== undefined && evt.preventDefault) evt.preventDefault();
dispatch(loadRepos())
.then(
() => {
browserHistory.push('/');
}
)}
};
}
が、エラー
