import { Dropdown, Menu, Space } from 'antd';
import React, { useState } from 'react';
const menu = (
<Menu
items={[
{
label: 'Submit and continue',
key: '1',
},
]}
/>
);
const App: React.FC = () => {
const [loadings, setLoadings] = useState<boolean[]>([]);
const enterLoading = (index: number) => {
setLoadings(state => {
const newLoadings = [...state];
newLoadings[index] = true;
return newLoadings;
});
setTimeout(() => {
setLoadings(state => {
const newLoadings = [...state];
newLoadings[index] = false;
return newLoadings;
});
}, 6000);
