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}
        />
    )
  }
}

对于debounce，你需要在event.persist()中保留原始的合成事件。下面是用React 16+测试的工作示例。

import React, { Component } from 'react';
import debounce from 'lodash/debounce'

class ItemType extends Component {

  evntHandler = debounce((e) => {
    console.log(e)
  }, 500);

  render() {
    return (
      <div className="form-field-wrap"
      onClick={e => {
        e.persist()
        this.evntHandler(e)
      }}>
        ...
      </div>
    );
  }
}
export default ItemType;

使用功能组件，您可以做到这一点-

const Search = ({ getBooks, query }) => {

  const handleOnSubmit = (e) => {
    e.preventDefault();
  }
  const debouncedGetBooks = debounce(query => {
    getBooks(query);
  }, 700);

  const onInputChange = e => {
    debouncedGetBooks(e.target.value)
  }

  return (
    <div className="search-books">
      <Form className="search-books--form" onSubmit={handleOnSubmit}>
        <Form.Group controlId="formBasicEmail">
          <Form.Control type="text" onChange={onInputChange} placeholder="Harry Potter" />
          <Form.Text className="text-muted">
            Search the world's most comprehensive index of full-text books.
          </Form.Text>
        </Form.Group>
        <Button variant="primary" type="submit">
          Search
        </Button>
      </Form>
    </div>
  )
}

一个漂亮干净的解决方案，不需要任何外部依赖:

与React挂钩反弹

它使用了一个自定义加上useEffect React钩子和setTimeout / clearTimeout方法。

class UserListComponent extends Component {
    constructor(props) {
        super(props);
        this.searchHandler = this.keyUpHandler.bind(this);
        this.getData = this.getData.bind(this);
        this.magicSearch = this.magicSearch.bind(this,500);
    }
    getData = (event) => {
        console.log(event.target.value);
    }
    magicSearch = function (fn, d) {
        let timer;
        return function () {
            let context = this;
            clearTimeout(timer);
            timer = setTimeout(() => {
                fn.apply(context, arguments)
            }, d);
        }
    }
    keyUpHandler = this.magicSearch(this.getData, 500);
    render() {
        return (
             <input type="text" placeholder="Search" onKeyUp={this.searchHandler} />
        )
    }
}

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)} />)
  }
}

您可以使用Lodash debounce https://lodash.com/docs/4.17.5#debounce方法。它简单有效。

import * as lodash from lodash;

const update = (input) => {
    // Update the input here.
    console.log(`Input ${input}`);     
}

const debounceHandleUpdate = lodash.debounce((input) => update(input), 200, {maxWait: 200});

doHandleChange() {
   debounceHandleUpdate(input);
}

您还可以使用下面的方法取消debounce方法。

this.debounceHandleUpdate.cancel();

希望对你有所帮助。干杯! !
