要实现AG Grid SSRM树状数据与分页,可以按照以下步骤操作:
import React, { useEffect, useState } from 'react';
import { AgGridReact } from 'ag-grid-react';
import 'ag-grid-community/dist/styles/ag-grid.css';
import 'ag-grid-community/dist/styles/ag-theme-alpine.css';
const columnDefs = [
{ field: 'name' },
{ field: 'size' },
{ field: 'type' }
];
const defaultColDef = {
resizable: true,
sortable: true
};
const AgGridSSRMTreeDataWithPagination = () => {
const [rowData, setRowData] = useState([]);
const [paginationPageSize, setPaginationPageSize] = useState(10);
const [paginationTotalRows, setPaginationTotalRows] = useState(0);
useEffect(() => {
// 获取树状数据并更新rowData和paginationTotalRows
const fetchData = async () => {
const response = await fetch('api/getTreeData');
const data = await response.json();
setRowData(data);
setPaginationTotalRows(data.length);
};
fetchData();
}, []);
const onGridReady = (params) => {
params.api.sizeColumnsToFit();
};
const onPaginationPageLoaded = (params) => {
// 根据当前页码和每页显示的数量计算分页数据的起始索引和结束索引
const startIndex = (params.page - 1) * paginationPageSize;
const endIndex = startIndex + paginationPageSize;
// 从rowData中提取分页数据
const pageData = rowData.slice(startIndex, endIndex);
// 设置当前页的数据
params.successCallback(pageData);
};
return (
params.value.toLocaleString()}
cacheBlockSize={paginationPageSize}
maxBlocksInCache={10}
onGridReady={onGridReady}
onPaginationPageLoaded={onPaginationPageLoaded}
/>
);
};
export default AgGridSSRMTreeDataWithPagination;
以上代码示例提供了一个基本的AG Grid SSRM树状数据与分页的解决方案。你可以根据自己的需求进行修改和扩展。
