现在，React和React Native在2019年底有了另一个解决方案:

react-debounce-component

<input>
<Debounce ms={500}>
  <List/>
</Debounce>

它是一个组件，易于使用，体积小，支持广泛

例子:

import React from 'react';
import Debounce from 'react-debounce-component';

class App extends React.Component {
  constructor (props) {
    super(props);
    this.state = {value: 'Hello'}
  }
  render () {
    return (
      <div>
        <input value={this.state.value} onChange={(event) => {this.setState({value: event.target.value})}}/>
        <Debounce ms={1000}>
          <div>{this.state.value}</div>
        </Debounce>
      </div>
    );
  }
}

export default App;

我是这个组件的创建者

这里已经有很多好的信息了，但为了简洁。这对我很有用……

import React, {Component} from 'react';
import _ from 'lodash';

class MyComponent extends Component{
      constructor(props){
        super(props);
        this.handleChange = _.debounce(this.handleChange.bind(this),700);
      }; 

/**
 * Returns a function with the same signature of input `callback` (but without an output) that if called, smartly
 * executes the `callback` in a debounced way.<br>
 * There is no `delay` (to execute the `callback`) in the self-delayed tries (try = calling debounced callback). It
 * will defer **only** subsequent tries (that are earlier than a minimum timeout (`delay` ms) after the latest
 * execution). It also **cancels stale tries** (that have been obsoleted because of creation of newer tries during the
 * same timeout).<br>
 * The timeout won't be expanded! So **the subsequent execution won't be deferred more than `delay`**, at all.
 * @param {Function} callback
 * @param {number} [delay=167] Defaults to `167` that is equal to "10 frames at 60 Hz" (`10 * (1000 / 60) ~= 167 ms`)
 * @return {Function}
 */
export function smartDebounce (callback, delay = 167) {
  let minNextExecTime = 0
  let timeoutId

  function debounced (...args) {
    const now = new Date().getTime()
    if (now > minNextExecTime) { // execute immediately
      minNextExecTime = now + delay // there would be at least `delay` ms between ...
      callback.apply(this, args) // ... two consecutive executions
      return
    }
    // schedule the execution:
    clearTimeout(timeoutId) // unset possible previous scheduling
    timeoutId = setTimeout( // set new scheduling
      () => {
        minNextExecTime = now + delay // there would be at least `delay` ms between ...
        callback.apply(this, args) // ... two consecutive executions
      },
      minNextExecTime - now, // 0 <= timeout <= `delay` ... (`minNextExecTime` <= `now` + `delay`)
    )
  }

  debounced.clear = clearTimeout.bind(null, timeoutId)

  return debounced
}

/**
 * Like React's `useCallback`, but will {@link smartDebounce smartly debounce} future executions.
 * @param {Function} callback
 * @param {[]} deps
 * @param {number} [delay=167] - Defaults to `167` that is equal to "10 frames at 60 Hz" (`10 * (1000 / 60) ~= 167 ms`)
 */
export const useDebounced = (callback, deps, delay = 167) =>
  useMemo(() => smartDebounce(callback, delay), [...deps, delay])

您可以使用Lodash debounce https://lodash.com/docs/4.17.5#debounce方法。它简单有效。

import * as lodash from lodash;

const update = (input) => {
    // Update the input here.
    console.log(`Input ${input}`);     
}

const debounceHandleUpdate = lodash.debounce((input) => update(input), 200, {maxWait: 200});

doHandleChange() {
   debounceHandleUpdate(input);
}

您还可以使用下面的方法取消debounce方法。

this.debounceHandleUpdate.cancel();

希望对你有所帮助。干杯! !

对于debounce，你需要在event.persist()中保留原始的合成事件。下面是用React 16+测试的工作示例。

import React, { Component } from 'react';
import debounce from 'lodash/debounce'

class ItemType extends Component {

  evntHandler = debounce((e) => {
    console.log(e)
  }, 500);

  render() {
    return (
      <div className="form-field-wrap"
      onClick={e => {
        e.persist()
        this.evntHandler(e)
      }}>
        ...
      </div>
    );
  }
}
export default ItemType;

使用功能组件，您可以做到这一点-

const Search = ({ getBooks, query }) => {

  const handleOnSubmit = (e) => {
    e.preventDefault();
  }
  const debouncedGetBooks = debounce(query => {
    getBooks(query);
  }, 700);

  const onInputChange = e => {
    debouncedGetBooks(e.target.value)
  }

  return (
    <div className="search-books">
      <Form className="search-books--form" onSubmit={handleOnSubmit}>
        <Form.Group controlId="formBasicEmail">
          <Form.Control type="text" onChange={onInputChange} placeholder="Harry Potter" />
          <Form.Text className="text-muted">
            Search the world's most comprehensive index of full-text books.
          </Form.Text>
        </Form.Group>
        <Button variant="primary" type="submit">
          Search
        </Button>
      </Form>
    </div>
  )
}

你可以用沉默

function log(server) {
  console.log('connecting to', server);
}

const debounceLog = debounce(log, 5000);
// just run last call to 5s
debounceLog('local');
debounceLog('local');
debounceLog('local');
debounceLog('local');
debounceLog('local');
debounceLog('local');
