```tsx
|
|
|
|
import { message, Popconfirm, Switch } from 'antd';
|
|
|
|
import React, { useState } from 'react';
|
|
|

|
setVisible(false);

|
|
|
message.success('Next step.');

|
|

return;
|
|

}
|

|
// Determining condition before show the popconfirm.
|
|
|

console.log(condition);

if (condition) {
|
|

confirm(); // next step
|
|

} else {

}
|

};

Whether directly execute:

</div>
|

);
