I am having trouble with useState
and state change in a React Functional Component. I am using an imported package called Menu
that takes a prop called " isOpen " - when set to true the Menu (similar to a modal) is displayed.
When I click on the "Close Menu" button that is within the Menu modal, the state for menuOpen
changes to false - however, the isOpen prop does not switch from true to false - and therefore the menu does not close. Or else Am I missing something here?
const MenuButton: React.FC<Props> = () => {
const [menuOpen, setMenuOpen] = useState(false)
const openMenu = () => {
setMenuOpen(true)
}
const closeMenu = () => {
setMenuOpen(false)
}
return (
<Menu buttonNode={<Button onClick={openMenu}>Open
Menu</Button>} isOpen={menuOpen}>
<Box>
<Text>Menu Heading</Text>
<Button onClick={closeMenu}>Close Menu</Button>
</Box>
</Menu>
)
}
It's definitely a problem with 'pcln-menu' package as it's developers don't use the single source of truth principle when designing component's state.
You should pass menu content as renderContent
property to obtain handleClose
callback. Try this:
const MenuButton = () => {
const [menuOpen, setMenuOpen] = useState(false);
const openMenu = () => {
setMenuOpen(true);
};
return (
<Menu
buttonNode={<Button onClick={openMenu}>Open Menu</Button>}
isOpen={menuOpen}
renderContent={({handleClose}) => (
<Box>
<Text>Menu Heading</Text>
<Button onClick={handleClose}>Close Menu</Button>
</Box>
)}
></Menu>
);
};
