I'm making a search bar. However, an error occurs.
If you erase 'toLowerCase', the next 'includes' will fail. I keep getting an error.
The data was received without any problem.
Why did you do that? I'm a beginner. Help me, please.
Data from the console log.
import React, { useState, useEffect } from "react";
import axios from "axios";
const Searchs = () => {
const url = "https://www.thecocktaildb.com/api/json/v1/1/search.php?s";
const [searchTerm, setSearchTerm] = useState("");
const [searchValue, setSearchValue] = useState("");
const [results, setResults] = useState([]);
useEffect(() => {
axios
.get(url)
.then((res) => {
console.log(res);
setResults(res.data.drinks);
console.log(res.data);
})
.catch((error) => {
console.log(error);
});
}, []);
const searchHandler = (value) => {
setSearchValue(value);
};
let updateUsers = results.filter(({ strdrink }) => {
return strdrink.toLowerCase.includes(searchValue);
}, []);
const handleSearchInputChange = (e) => {
searchHandler(e.target.value);
};
return (
<Wrapper>
<form>
<input
type="text"
placeholder="재료 또는 이름을 검색하세요"
value={searchTerm}
onChange={handleSearchInputChange}
/>
</form>
<ul>
{(searchValue === "" ? results : updateUsers).map(
({ idDrink, strAlcoholic, strDrinkThumb, strDrink }) => (
<li key={`${idDrink}`}>
<br />
{`${strDrink}`} <br />
{`${strAlcoholic}`} <br />
{`${strDrinkThumb}`}
</li>
)
)}
</ul>
</Wrapper>
);
};
export default Searchs;
Two changes here
`return strdrink.toLowerCase.includes(searchValue);`
Change strdrink
to strDrink
. Keys are case sensitive
toLowerCase
is a function. Use like toLowerCase()
