我正在构建一个带有 AgGridReact
的 React 功能组件:
const DataGrid = (props) =>
{
const [gridRowData, setGridRowData] = useState([]);
const [columnDefinition, setColumnDefinition] = useState([]);
useEffect(async () =>
{
if(props.name && props.name !== "")
{
... get grid row data and column definition here according to props.name - working fine
}
},[props.name]);
let frameworkComponents = {
customLoadingOverlay: LoadingOverlayTemplate,
customNoRowsOverlay: UxDataGridCustomNoRows,
editButton: params => <ViewAndDeleteSetting {...params}
openAddConfigurationsWindow={openAddConfigurationsWindow}
onDeleteSetting={onDeleteSetting} />
};
.
.
.
const onDeleteSetting = async () =>
{
console.log("ON DELETE AND NAME IS: " + props.name ); //PRINTS AN EMPTY STRING
...
}
return (
<AgGridReact
columnDefs={columnDefinition}
rowData={gridRowData}
frameworkComponents={frameworkComponents}/>
);
正如您在 onDeleteSetting
中的注释中所见,调用此回调时名称为空。单元格本身的渲染很好,并且确实渲染了 ViewAndDeleteSetting
,只是它似乎只渲染一次,而不是每次更改名称时。如何使用最新的 ViewAndDeleteSetting
重新呈现内部 frameworkComponents
组件?
答案 0 :(得分:0)
问题在于我如何尝试将 props 传递给 ViewAndDeleteSetting
。如果要将 prop 传递给单元格渲染组件,则不应在 frameworkComponents
中执行此操作,而需要在列定义中执行此操作,如下所示:
useEffect(() =>
{
let columns = [{headerName: '', cellRenderer: 'editButton', width: 90, editable: false,
cellRendererParams: {
openAddConfigurationsWindow: openAddConfigurationsWindow,
onDeleteSetting: onDeleteSetting
}},
.. other columns
]
setColumnDefinition(columns);
},[props.name]);
当名称更改时,带有 cellRendererParams
的列会在 useEffect
中重新创建,然后组件可以通过其 props 定期访问此参数
