你试过吗?

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

var SearchBox = React.createClass({
  render: function() {
    return <input type="search" name="p" onChange={this.handleOnChange} />;
  },

  handleOnChange: function(event) {
    debounce(\\ Your handleChange code , 200);
  }
});

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)

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);
}

如果我们有兴趣在react.js中使用epic.js，我们可以在epic.js库中使用debounceTime rxjs/操作符。因此，我们可以在epic.js的帮助下，在react.js中使用可观察对象，而不是使用回调。

FYI

这是另一个PoC实现:

没有任何库(例如lodash)用于debound 使用React Hooks API

我希望它能帮助你:)

import React, { useState, useEffect, ChangeEvent } from 'react';

export default function DebouncedSearchBox({
  inputType,
  handleSearch,
  placeholder,
  debounceInterval,
}: {
  inputType?: string;
  handleSearch: (q: string) => void;
  placeholder: string;
  debounceInterval: number;
}) {
  const [query, setQuery] = useState<string>('');
  const [timer, setTimer] = useState<NodeJS.Timer | undefined>();

  useEffect(() => {
    if (timer) {
      clearTimeout(timer);
    }
    setTimer(setTimeout(() => {
      handleSearch(query);
    }, debounceInterval));
  }, [query]);

  const handleOnChange = (e: ChangeEvent<HTMLInputElement>): void => {
    setQuery(e.target.value);
  };

  return (
    <input
      type={inputType || 'text'}
      className="form-control"
      placeholder={placeholder}
      value={query}
      onChange={handleOnChange}
    />
  );
}

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>
  );
}
