我的actionFormatter有问题。
当我单击DELETE按钮时,出现错误:
未捕获的ReferenceError:在onClick上未定义调度
我该如何解决这个问题?
import { removeEnvironnement } from '../../actions/environnement';
const EnvironnementList = (props) => (
<BootstrapTable
keyField='id'
data={ props.store.environnements }
columns={ columns }
selectRow={selectRow}
pagination={ paginationFactory() }
filter={ filterFactory() }
striped hover condensed
/>
);
const actionsFormatter = (cell, row) => {
const id=row.id
return (
<button className="btn btn-danger"
onClick={() => {
dispatch(removeEnvironnement({ id }));}}
>Delete</button>
);
};
const columns = [{
dataField: 'id',
text: 'ID'
}, {
dataField: 'nom',
text: 'Nom',
filter: textFilter()
}, {
dataField: 'actions',
text: 'Action',
formatter: actionsFormatter
} ];
const selectRow = {
mode: 'checkbox',
clickToSelect: true,
bgColor: '#00BFFF'
};
const mapStateToProps = (state) => {
return {
store: state
};
}
export default connect(mapStateToProps)(EnvironnementList);
这是我执行删除的代码:
我应该删除调度部分吗?
const _removeEnvironnement = ({ id } = {}) => ({
type: 'REMOVE_ENVIRONNEMENT',
id
});
export const removeEnvironnement = ({ id } = {}) => {
return (dispatch) => {
return axios.delete(`environnements/${id}`).then(() => {
dispatch(_removeEnvironnement({ id }));
})
}
};
最佳答案
您的dispatch
中的actionsFormatter
是什么?它既不在actionsFormatter
范围内定义,也未在actionsFormatter
范围外定义。这就是问题,这就是您正在谈论的javascript解释器。
可能的解决方法之一是导入redux存储
store.js
export const store = createStore(...)
EnvironmentList.js
import { store } from './path/to/store.js'
// ...
const actionsFormatter = (cell, row) => {
const { dispatch } = store
const id = row.id
// ...
};
这样,您将在
dispatch
正文中获得actionsFormatter
可用。另一种方法是通过connect-> EnvironmentList-> actionsFormatter链提供映射方法。执行Arnaud Christ的建议in his reply,然后重构代码:
const EnvironmentList = (props) => (
<BootstrapTable
keyField='id'
data={ props.store.environnements }
columns={ columns(props.removeEnvironment) }
selectRow={selectRow}
pagination={ paginationFactory() }
filter={ filterFactory() }
striped hover condensed
/>
);
const actionsFormatter = (removeEnvironment) => (cell, row) => {
const id=row.id
return (
<button className="btn btn-danger"
onClick={() => {
removeEnvironment({ id });
}}
>Delete</button>
);
};
const columns = (removeEnvironment) => [{
dataField: 'id',
text: 'ID'
}, {
dataField: 'nom',
text: 'Nom',
filter: textFilter()
}, {
dataField: 'actions',
text: 'Action',
formatter: actionsFormatter(removeEnvironment)
} ];
因此,连接的EnvironmentList在其道具上获得了必要的removeEnvironment方法。然后我们将其传递给列创建器,列创建器将其传递给actionsFormatter创建器。
