React搜索使用debounce

Question

我正试图实现一个搜索，使每个字符变化的新查询。在n毫秒后，我需要对存储某些属性的对象进行更改。

//user typing
const onInputChange = (e) => {
let searchInput = e.target.value;
useDebounce(
handleSearchPropsChange({
filter: {
searchInput,
dateRange: {
start,
end
}
}
}), 1000
);
}

我用于延迟呼叫的函数

import {debounce} from 'lodash';
import {useRef} from 'react';
export function useDebounce(callback = () => {}, time = 500) {
return useRef(debounce(callback, time)).current;
}

但是我得到错误:

Invalid hook call. Hooks can only be called inside of the body of a function component. This 
could happen for one of the following reasons:
1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app

Answer 1

一个没有lodash的例子，只有Hooks。

UseDebounce.js

import { useEffect, useCallback } from 'react';
export default function useDebounce(effect, dependencies, delay) {
const callback = useCallback(effect, dependencies);
useEffect(() => {
const timeout = setTimeout(callback, delay);
return () => clearTimeout(timeout);
}, [callback, delay]);
}

App.js

import React, { useState } from 'react';
import useDebounce from './useDebounce';
import data from './data';
export default function App() {
const [search, setSearch] = useState('');
const [filteredTitle, setFilteredTitle] = useState([]);
// DeBounce Function
useDebounce(() => {
setFilteredTitle(
data.filter((d) => d.title.toLowerCase().includes(search.toLowerCase()))
);
}, [data, search], 800
);
const handleSearch = (e) => setSearch(e.target.value);
return (
<>
<input
id="search"
type="text"
spellCheck="false"
placeholder="Search a Title"
value={search || ''}
onChange={handleSearch}
/>
<div>
{filteredTitle.map((f) => (
<p key={f.id}>{f.title}</p>
))}
</div>
</>
);
}
