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)

您可以使用引用变量来存储计时器，然后将其清除。下面是一个不使用任何第三方包在react中实现deboundation的例子

import { useState, useRef } from "react";
import "./styles.css";

export default function App() {
  // Variables for debouncing
  const [text, setText] = useState("");
  const timer = useRef();

  // Variables for throtteling
  const [throttle, setThrottle] = useState(false)


  const handleDebouncing = ({ target }) => {
    clearTimeout(timer.current)

    timer.current = setTimeout(() => {
      callApi();
    }, 300);

    setText(target.value);
  };

  const handleThrottleing = () => {
    callApi()

    setThrottle(true)

    setTimeout(() => {
      setThrottle(false)
    }, 2000)
  }

  const callApi = () => {
    console.log("Calling Api");
  };

  return (
    <div className="App">
      <input type="text" onChange={handleDebouncing} />

      <button onClick={handleThrottleing} disabled={throttle} >Click me to see throtteling</button>
    </div>
  );
}

如果你只需要从事件对象中获取DOM输入元素，解决方案就简单多了——只需要使用ref。注意，这需要下划线:

class Item extends React.Component {
    constructor(props) {
        super(props);
        this.saveTitle = _.throttle(this.saveTitle.bind(this), 1000);
    }
    saveTitle(){
        let val = this.inputTitle.value;
        // make the ajax call
    }
    render() {
        return <input 
                    ref={ el => this.inputTitle = el } 
                    type="text" 
                    defaultValue={this.props.title} 
                    onChange={this.saveTitle} />
    }
}

/**
 * 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

 */
export const useDebounced = (callback, deps, delay = 167) =>
  useMemo(() => smartDebounce(callback, delay), [...deps, delay])

与其在debounce()中包装handleOnChange，不如在debounce()中包装回调函数中的ajax调用，从而不破坏事件对象。就像这样:

handleOnChange: function (event) {
   debounce(
     $.ajax({})
  , 250);
}

不受控制的组件

你可以使用event.persist()方法。

下面是一个使用下划线_.debounce()的例子:

var SearchBox = React.createClass({

  componentWillMount: function () {
     this.delayedCallback = _.debounce(function (event) {
       // `event.target` is accessible now
     }, 1000);
  },

  onChange: function (event) {
    event.persist();
    this.delayedCallback(event);
  },

  render: function () {
    return (
      <input type="search" onChange={this.onChange} />
    );
  }

});

控制组件

更新:上面的例子显示了一个不受控制的组件。我一直在使用受控元素，这里是上面的另一个例子，但没有使用event.persist()“欺骗”。

JSFiddle也是可用的。不带下划线的示例

var SearchBox = React.createClass({
    getInitialState: function () {
        return {
            query: this.props.query
        };
    },

    componentWillMount: function () {
       this.handleSearchDebounced = _.debounce(function () {
           this.props.handleSearch.apply(this, [this.state.query]);
       }, 500);
    },

    onChange: function (event) {
      this.setState({query: event.target.value});
      this.handleSearchDebounced();
    },

    render: function () {
      return (
        <input type="search"
               value={this.state.query}
               onChange={this.onChange} />
      );
    }
});


var Search = React.createClass({
    getInitialState: function () {
        return {
            result: this.props.query
        };
    },

    handleSearch: function (query) {
        this.setState({result: query});
    },

    render: function () {
      return (
        <div id="search">
          <SearchBox query={this.state.result}
                     handleSearch={this.handleSearch} />
          <p>You searched for: <strong>{this.state.result}</strong></p>
        </div>
      );
    }
});

React.render(<Search query="Initial query" />, document.body);
