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)

下面是我想出的一个用debouncer包装另一个类的例子。这使得自己很好地成为一个装饰器/高阶函数:

export class DebouncedThingy extends React.Component {
    static ToDebounce = ['someProp', 'someProp2'];
    constructor(props) {
        super(props);
        this.state = {};
    }
    // On prop maybe changed
    componentWillReceiveProps = (nextProps) => {
        this.debouncedSetState();
    };
    // Before initial render
    componentWillMount = () => {
        // Set state then debounce it from here on out (consider using _.throttle)
        this.debouncedSetState();
        this.debouncedSetState = _.debounce(this.debouncedSetState, 300);
    };
    debouncedSetState = () => {
        this.setState(_.pick(this.props, DebouncedThingy.ToDebounce));
    };
    render() {
        const restOfProps = _.omit(this.props, DebouncedThingy.ToDebounce);
        return <Thingy {...restOfProps} {...this.state} />
    }
}

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

今天遇到了这个问题。使用setTimeout和clearTimeout解决。

我将给出一个你可以适应的例子:

import React, { Component } from 'react'

const DEBOUNCE_TIME = 500

class PlacesAutocomplete extends Component {
  debounceTimer = null;

  onChangeHandler = (event) => {
    // Clear the last registered timer for the function
    clearTimeout(this.debounceTimer);

    // Set a new timer
    this.debounceTimer = setTimeout(
      // Bind the callback function to pass the current input value as arg
      this.getSuggestions.bind(null, event.target.value), 
      DEBOUNCE_TIME
    )
  }

  // The function that is being debounced
  getSuggestions = (searchTerm) => {
    console.log(searchTerm)
  }

  render() {
    return (
      <input type="text" onChange={this.onChangeHandler} />
    )
  }
}

export default PlacesAutocomplete

你也可以在它自己的函数组件中重构它:

import React from 'react'

function DebouncedInput({ debounceTime, callback}) {
  let debounceTimer = null
  return (
    <input type="text" onChange={(event) => {
      clearTimeout(debounceTimer);

      debounceTimer = setTimeout(
        callback.bind(null, event.target.value), 
        debounceTime
      )
    }} />
  )
}

export default DebouncedInput

像这样使用它:

import React, { Component } from 'react'
import DebouncedInput from '../DebouncedInput';

class PlacesAutocomplete extends Component {
  debounceTimer = null;

  getSuggestions = (searchTerm) => {
    console.log(searchTerm)
  }

  render() {
    return (
      <DebouncedInput debounceTime={500} callback={this.getSuggestions} />
    )
  }
}

export default PlacesAutocomplete

有点晚了，但应该有帮助。 创建这个类(它是用typescript写的，但是很容易转换成javascript)

export class debouncedMethod<T>{
  constructor(method:T, debounceTime:number){
    this._method = method;
    this._debounceTime = debounceTime;
  }
  private _method:T;
  private _timeout:number;
  private _debounceTime:number;
  public invoke:T = ((...args:any[])=>{
    this._timeout && window.clearTimeout(this._timeout);
    this._timeout = window.setTimeout(()=>{
      (this._method as any)(...args);
    },this._debounceTime);
  }) as any;
}

要使用

var foo = new debouncedMethod((name,age)=>{
 console.log(name,age);
},500);
foo.invoke("john",31);

这个解决方案不需要任何额外的库，它也会在用户按下enter时启动:

const debounce = (fn, delay) => {
    let timer = null;
    return function() {
        const context = this,
        args = arguments;
        clearTimeout(timer);
        timer = setTimeout(() => {
            fn.apply(context, args);
        }, delay);
    };  
}

const [search, setSearch] = useState('');
const [searchFor, setSearchFor] = useState(search);

useEffect(() => {
    console.log("Search:", searchFor);
}, [searchFor]);

const fireChange = event => {
    const { keyCode } = event;
    if (keyCode === 13) {
        event.preventDefault();
        setSearchFor(search);
    }
}

const changeSearch = event => {
    const { value } = event.target;
    setSearch(value);
    debounceSetSearchFor(value);
};

const debounceSetSearchFor = useCallback(debounce(function(value) {
    setSearchFor(value);
}, 250), []);

输入可以是这样的:

<input value={search} onKeyDown={fireChange} onChange={changeSearch}  />
