如果你正在使用redux，你可以通过中间件以一种非常优雅的方式做到这一点。你可以这样定义Debounce中间件:

var timeout;
export default store => next => action => {
  const { meta = {} } = action;
  if(meta.debounce){
    clearTimeout(timeout);
    timeout = setTimeout(() => {
      next(action)
    }, meta.debounce)
  }else{
    next(action)
  }
}

然后你可以添加debounging到动作创建者，比如:

export default debouncedAction = (payload) => ({
  type : 'DEBOUNCED_ACTION',
  payload : payload,
  meta : {debounce : 300}
}

实际上已经有中间件你可以脱离npm来为你做这件事。

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! !

Julen的解决方案有点难以阅读，这里有更清晰和准确的反应代码，供那些根据标题而不是问题的微小细节绊倒他的人使用。

Tl;dr版本:当你要更新到观察者发送调用一个调度方法，反过来实际上会通知观察者(或执行ajax等)

使用示例组件jsfiddle完成jsfiddle

var InputField = React.createClass({

    getDefaultProps: function () {
        return {
            initialValue: '',
            onChange: null
        };
    },

    getInitialState: function () {
        return {
            value: this.props.initialValue
        };
    },

    render: function () {
        var state = this.state;
        return (
            <input type="text"
                   value={state.value}
                   onChange={this.onVolatileChange} />
        );
    },

    onVolatileChange: function (event) {
        this.setState({ 
            value: event.target.value 
        });

        this.scheduleChange();
    },

    scheduleChange: _.debounce(function () {
        this.onChange();
    }, 250),

    onChange: function () {
        var props = this.props;
        if (props.onChange != null) {
            props.onChange.call(this, this.state.value)
        }
    },

});

这里已经有很多好的信息了，但为了简洁。这对我很有用……

import React, {Component} from 'react';
import _ from 'lodash';

class MyComponent extends Component{
      constructor(props){
        super(props);
        this.handleChange = _.debounce(this.handleChange.bind(this),700);
      }; 

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);
  }
});
