自定义渲染每一个 Transfer Item,可用于渲染复杂数据。
en-US
Custom each Transfer Item, and in this way you can render a complex datasource.
import { Transfer } from 'antd';
import type { TransferDirection } from 'antd/es/transfer';
import React, { useEffect, useState } from 'react';
interface RecordType {
key: string;
title: string;
description: string;
chosen: boolean;
}
const App: React.FC = () => {
const [mockData, setMockData] = useState<RecordType[]>([]);
const [targetKeys, setTargetKeys] = useState<string[]>([]);
const getMock = () => {
const tempTargetKeys = [];
const tempMockData = [];
for (let i = 0; i < 20; i++) {
const data = {
key: i.toString(),
title: `content${i + 1}`,
description: `description of content${i + 1}`,
chosen: Math.random() * 2 > 1,
};
if (data.chosen) {
tempTargetKeys.push(data.key);
}
tempMockData.push(data);
}
setMockData(tempMockData);
setTargetKeys(tempTargetKeys);
};
useEffect(() => {
getMock();
}, []);
const handleChange = (
newTargetKeys: string[],
direction: TransferDirection,
moveKeys: string[],
) => {
console.log(newTargetKeys, direction, moveKeys);
setTargetKeys(newTargetKeys);
};
const renderItem = (item: RecordType) => {
const customLabel = (
<span className="custom-item">
{item.title} - {item.description}
</span>
);
return {
label: customLabel, // for displayed item
value: item.title, // for title and filter matching
};
};
return (
<Transfer
dataSource={mockData}
listStyle={{
width: 300,
height: 300,
}}
targetKeys={targetKeys}
onChange={handleChange}
render={renderItem}
/>
);
};
export default App;
