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);
      }; 

你可以在ReactJS钩子中使用一个use-debounce包。

从包的README:

import { useDebounce } from 'use-debounce';

export default function Input() {
  const [text, setText] = useState('Hello');
  const [value] = useDebounce(text, 1000);

  return (
    <div>
      <input
        defaultValue={'Hello'}
        onChange={(e) => {
          setText(e.target.value);
        }}
      />
      <p>Actual value: {text}</p>
      <p>Debounce value: {value}</p>
    </div>
  );
}

从上面的示例中可以看到，它设置为每秒钟更新一次变量值(1000毫秒)。

我发现Justin Tulk的这篇文章很有帮助。在经过几次尝试后，人们会认为这是react/redux更正式的方式，结果显示它失败了，因为react的合成事件池。然后，他的解决方案使用一些内部状态来跟踪在输入中更改/输入的值，在setState之后使用一个回调，调用一个throttled/ deboundredux动作，实时显示一些结果。

import React, {Component} from 'react'
import TextField from 'material-ui/TextField'
import { debounce } from 'lodash'

class TableSearch extends Component {

  constructor(props){
    super(props)

    this.state = {
        value: props.value
    }

    this.changeSearch = debounce(this.props.changeSearch, 250)
  }

  handleChange = (e) => {
    const val = e.target.value

    this.setState({ value: val }, () => {
      this.changeSearch(val)
    })
  }

  render() {

    return (
        <TextField
            className = {styles.field}
            onChange = {this.handleChange}
            value = {this.props.value}
        />
    )
  }
}

我的解决方案是基于钩子(用Typescript编写)。

我有2个主要钩子useDebouncedValue和useDebouncedCallback

First - useDebouncedValue

假设我们有一个搜索框，但是我们想在用户停止输入0.5秒后向服务器请求搜索结果

function SearchInput() {
  const [realTimeValue, setRealTimeValue] = useState('');

  const debouncedValue = useDebouncedValue(realTimeValue, 500); // this value will pick real time value, but will change it's result only when it's seattled for 500ms

  useEffect(() => {
    // this effect will be called on seattled values
    api.fetchSearchResults(debouncedValue);
  }, [debouncedValue])

  return <input onChange={event => setRealTimeValue(event.target.value)} />
}

实现

import { useState, useEffect } from "react";

export function useDebouncedValue<T>(input: T, time = 500) {
  const [debouncedValue, setDebouncedValue] = useState(input);

  // every time input value has changed - set interval before it's actually commited
  useEffect(() => {
    const timeout = setTimeout(() => {
      setDebouncedValue(input);
    }, time);

    return () => {
      clearTimeout(timeout);
    };
  }, [input, time]);

  return debouncedValue;
}

第二个useDebouncedCallback

它只是在你的组件范围内创建一个“debpublished”函数。

假设我们有一个带有按钮的组件，在你停止点击它后，它将显示警报500毫秒。

function AlertButton() {
  function showAlert() {
    alert('Clicking has seattled');
  }

  const debouncedShowAlert = useDebouncedCallback(showAlert, 500);

  return <button onClick={debouncedShowAlert}>Click</button>
}

实现(注意我使用lodash/debounce作为辅助)

import debounce from 'lodash/debounce';
import { useMemo } from 'react';

export function useDebouncedCallback<T extends (...args: any) => any>(callback: T, wait?: number) {
  const debouncedCallback = useMemo(() => debounce(callback, wait), [callback, wait]);

  return debouncedCallback;
}

对于throttle或debounce，最好的方法是创建一个函数生成器，这样你就可以在任何地方使用它，例如:

  updateUserProfileField(fieldName) {
    const handler = throttle(value => {
      console.log(fieldName, value);
    }, 400);
    return evt => handler(evt.target.value.trim());
  }

在你的渲染方法中，你可以这样做:

<input onChange={this.updateUserProfileField("givenName").bind(this)}/>

updateUserProfileField方法将在每次调用它时创建一个单独的函数。

注意不要尝试直接返回处理程序，例如，这将不起作用:

 updateUserProfileField(fieldName) {
    return evt => throttle(value => {
      console.log(fieldName, value);
    }, 400)(evt.target.value.trim());
  }

为什么这将不会工作的原因，因为这将生成一个新的油门函数每次事件调用而不是使用相同的油门函数，所以基本上油门将是无用的;)

此外，如果你使用debounce或throttle，你不需要setTimeout或clearTimeout，这实际上是我们使用它们的原因:P

I was searching for a solution to the same problem and came across this thread as well as some others but they had the same problem: if you are trying to do a handleOnChange function and you need the value from an event target, you will get cannot read property value of null or some such error. In my case, I also needed to preserve the context of this inside the debounced function since I'm executing a fluxible action. Here's my solution, it works well for my use case so I'm leaving it here in case anyone comes across this thread:

// at top of file:
var myAction = require('../actions/someAction');

// inside React.createClass({...});

handleOnChange: function (event) {
    var value = event.target.value;
    var doAction = _.curry(this.context.executeAction, 2);

    // only one parameter gets passed into the curried function,
    // so the function passed as the first parameter to _.curry()
    // will not be executed until the second parameter is passed
    // which happens in the next function that is wrapped in _.debounce()
    debouncedOnChange(doAction(myAction), value);
},

debouncedOnChange: _.debounce(function(action, value) {
    action(value);
}, 300)
