## zh-CN
可以判断是否需要弹出。
## en-US
Make it pop up under some conditions.
```tsx
import { message, Popconfirm, Switch } from 'antd';
import React, { useState } from 'react';
const App: React.FC = () => {
const [visible, setVisible] = useState(false);
const [condition, setCondition] = useState(true);
const changeCondition = (checked: boolean) => {
setCondition(checked);
};
const confirm = () => {
setVisible(false);
message.success('Next step.');
};
const cancel = () => {
setVisible(false);
message.error('Click on cancel.');
};
const handleVisibleChange = (newVisible: boolean) => {
if (!newVisible) {
setVisible(newVisible);
return;
}
// Determining condition before show the popconfirm.
console.log(condition);
if (condition) {
confirm(); // next step
} else {
setVisible(newVisible);
}
};
return (
<div>
<Popconfirm
title="Are you sure delete this task?"
visible={visible}
onVisibleChange={handleVisibleChange}
onConfirm={confirm}
onCancel={cancel}
okText="Yes"
cancelText="No"
>
<a href="#">Delete a task</a>
</Popconfirm>
<br />
<br />
Whether directly execute:
<Switch defaultChecked onChange={changeCondition} />
</div>
);
};
export default App;
```
