en-US
Use Modal.useModal to get contextHolder with context accessible issue.
import React, { createContext } from 'react';
import { Modal, Button, Space } from 'antd';
const ReachableContext = createContext<string | null>(null);
const UnreachableContext = createContext<string | null>(null);
const config = {
title: 'Use Hook!',
content: (
<>
<ReachableContext.Consumer>{name => `Reachable: ${name}!`}</ReachableContext.Consumer>
<br />
<UnreachableContext.Consumer>{name => `Unreachable: ${name}!`}</UnreachableContext.Consumer>
</>
),
};
const App: React.FC = () => {
const [modal, contextHolder] = Modal.useModal();
return (
<ReachableContext.Provider value="Light">
<Space>
<Button
onClick={() => {
modal.confirm(config);
}}
>
Confirm
</Button>
<Button
onClick={() => {
modal.warning(config);
}}
>
Warning
</Button>
<Button
onClick={() => {
modal.info(config);
}}
>
Info
</Button>
<Button
onClick={() => {
modal.error(config);
}}
>
Error
</Button>
</Space>
{/* `contextHolder` should always under the context you want to access */}
{contextHolder}
{/* Can not access this context since `contextHolder` is not in it */}
<UnreachableContext.Provider value="Bamboo" />
</ReachableContext.Provider>
);
};
export default App;
