Here I have the state, and I am trying to pass them into child component SearchBar
App Component (parent component)
// not related code ...
// search
const { search, setSearch } = useState("");
const handleSearch = (e) => {
setSearch(e.target.value);
};
// not related code ...
return (
<ContextProviders
// not related code ...
>
<div className="App">
<Navbar />
<SearchBar search={search} handleSearch={(e) => handleSearch(e)} />
<Outlet />
</div>
</ContextProviders>
);
}
Into SearchBar when I am typing something in order to trigger setState it shows up an error:
SearchBar (child component)
import { useState } from "react";
export default function SearchBar(props) {
// not related code ...
console.log(props);
return (
<>
<div>
<input
type="search"
value={props.search}
onChange={props.handleSearch}
// not related code ...
/>
</div>
</>
);
}
I need to get the value from the input field in the search component(child) into App component(parent), I try to pass a function which sets state into App, but it doesn't work, I get the error:
Uncaught TypeError: setSearch is not a function at handleSearch
Does anyone see the issue here?
You should initialize your state as:
const [search, setSearch] = useState("");
And pass the handleSearch
function like this:
<SearchBar search={search} handleSearch={handleSearch} />
