I am creating a Project where I need to get value of a component state value to another component.
How can I get the value?
react dropdown
menu.Which is a button. Link or Route
to A
dropdown that's why I can't get it with useParams()
B
component which will fetch data with passing language.language
state to B
const A = () => {
const [language, setLanguage] = useState('en');
return (
<Navbar expand="xl" bg='light' expand={false}>
<Container>
<DropdownButton id="dropdown-basic-button" title={<MdOutlineLanguage />}>
<Dropdown.Item as="button" onClick={() => setLanguage('en')}>English</Dropdown.Item>
<Dropdown.Item as="button" onClick={() => setLanguage('ar')}>العربية</Dropdown.Item>
<Dropdown.Item as="button" onClick={() => setLanguage('bn')}>বাংলা</Dropdown.Item>
</DropdownButton>
</Container>
</Navbar>
)
};
export default A
A
state value & set it to B
state. Then pass to useGetDataQuery
& fetch data.const B = () => {
let [language, setLanguage] = useState('en')
const { data } = useGetDataQuery({language })
return (
<>
</>
)
}
export default B
I'm using readux & @reduxjs/toolkit
to store fetch data. Can I store my language
data to here. Than how can get to from anywhere of my component.
react-rotuer-dom
v6 export default configureStore({
reducer: {
[dataOne.reducerPath]: dataOne.reducer,
[data2.reducerPath]: dataTwo.reducer,
},
middleware: (getDefaultMiddleware) =>
getDefaultMiddleware({
serializableCheck: false
}).concat([dataOne.middleware, dataTwo.middleware]),
})
Maybe instead of using useState
, you can use a global state by using useContext because I think your language
will be use on several places as request body and of course to edit the state value, you can combine it with useReducer .
// UPDATE
working code: https://codesandbox.io/s/sleepy-monad-21wnc
MyContext
import { useReducer, useContext, createContext } from "react";
const initialValue = {
language: "id"
// other: "value",
};
const AppContext = createContext(initialValue);
const AppReducer = (state, action) => {
switch (action.type) {
case "CHANGE_LANGUAGE":
return {
...state,
...action.payload
};
default:
return state;
}
};
const MyContext = ({ children }) => {
const [state, dispatch] = useReducer(AppReducer, initialValue);
return (
<AppContext.Provider value={[state, dispatch]}>
{children}
</AppContext.Provider>
);
};
export const useAppContext = () => useContext(AppContext);
export default MyContext;
this is the context
and reducer
component later on use in App.js
App.js
import A from "./A";
import B from "./B";
import MyContext from "./MyContext";
import "./styles.css";
export default function App() {
return (
<MyContext>
<div className="App">
<A />
<B />
</div>
</MyContext>
);
}
A.js
import { useAppContext } from "./MyContext";
const A = () => {
const [globalState, dispatch] = useAppContext();
const onChange = (e) => {
dispatch({
type: "CHANGE_LANGUAGE",
payload: {
[e.target.name]: e.target.value
}
});
};
return (
<>
<p>Start Of Component A </p>
<input value={globalState.language} name="language" onChange={onChange} />
<p>End Of Component A </p>
</>
);
};
export default A;
B.js
import { useAppContext } from "./MyContext";
const B = () => {
const [globalState, dispatch] = useAppContext();
return (
<>
<p>Start Of Component B </p>
<h2>Language Val : {globalState.language}</h2>
<p>End Of Component B </p>
</>
);
};
export default B;
