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

使用ES6 CLASS和React 15.x。X & lodash.debounce 我在这里使用React的refs，因为事件在内部失去了这个绑定。

class UserInput extends React.Component { constructor(props) { super(props); this.state = { userInput: "" }; this.updateInput = _.debounce(this.updateInput, 500); } updateInput(userInput) { this.setState({ userInput }); //OrderActions.updateValue(userInput);//do some server stuff } render() { return ( <div> <p> User typed: { this.state.userInput } </p> <input ref = "userValue" onChange = {() => this.updateInput(this.refs.userValue.value) } type = "text" / > </div> ); } } ReactDOM.render( < UserInput / > , document.getElementById('root') ); <script src="https://cdn.jsdelivr.net/npm/lodash@4.17.5/lodash.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script> <div id="root"></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} />
    }
}

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}
        />
    )
  }
}

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);

只是最近react和lodash的另一个变体。

class Filter extends Component {
  static propTypes = {
    text: PropTypes.string.isRequired,
    onChange: PropTypes.func.isRequired
  }

  state = {
    initialText: '',
    text: ''
  }

  constructor (props) {
    super(props)

    this.setText = this.setText.bind(this)
    this.onChange = _.fp.debounce(500)(this.onChange.bind(this))
  }

  static getDerivedStateFromProps (nextProps, prevState) {
    const { text } = nextProps

    if (text !== prevState.initialText) {
      return { initialText: text, text }
    }

    return null
  }

  setText (text) {
    this.setState({ text })
    this.onChange(text)
  }

  onChange (text) {
    this.props.onChange(text)
  }

  render () {
    return (<input value={this.state.text} onChange={(event) => this.setText(event.target.value)} />)
  }
}
