antd輸入框的函數(shù)防抖要怎么做

請問antd中輸入框的函數(shù)防抖要怎么弄?
這是我寫的一個(gè)測試代碼

import React from "react";
import ReactDOM from "react-dom";
import "antd/dist/antd.css";
import "./index.css";
import { Form, Input } from "antd";
import debounce from "lodash.debounce";

const FormItem = Form.Item;

const CustomizedForm = Form.create({
  onFieldsChange(props, changedFields) {
    props.onChange(changedFields);
  }
})(props => {
  const { getFieldDecorator } = props.form;
  return (
    <Form layout="inline">
      <FormItem label="Username">
        {getFieldDecorator("username", {
          rules: [{ required: true, message: "Username is required!" }]
        })(<Input />)}
      </FormItem>
    </Form>
  );
});

class Demo extends React.Component {
  state = {
    fields: {
      username: {
        value: "benjycui"
      }
    }
  };

  handleFormChange = changedFields => {
    if (changedFields["username"].validating === false) {
      debounce(() => {
        console.log("hahaha");
        this.setState(({ fields }) => ({
          fields: { ...fields, ...changedFields }
        }));
      }, 2000)();
    }
  };

  render() {
    const fields = this.state.fields;
    return (
      <div>
        <CustomizedForm {...fields} onChange={this.handleFormChange} />
        <pre className="language-bash">{JSON.stringify(fields, null, 2)}</pre>
        <button onClick={this.xxx}>click</button>
      </div>
    );
  }
}

ReactDOM.render(<Demo />, document.getElementById("container"));

import React from 'react';
import ReactDOM from 'react-dom';
import 'antd/dist/antd.css';
import './index.css';
import { Form, Input } from 'antd';

const FormItem = Form.Item;

const CustomizedForm = Form.create({
  onFieldsChange(props, changedFields) {
    props.onChange(changedFields);
  },
  mapPropsToFields(props) {
    return {
      username: Form.createFormField({
        ...props.username,
        value: props.username.value,
      }),
    };
  },
  onValuesChange(_, values) {
    console.log(values);
  },
})((props) => {
  const { getFieldDecorator } = props.form;
  return (
    <Form layout="inline">
      <FormItem label="Username">
        {getFieldDecorator('username', {
          rules: [{ required: true, message: 'Username is required!' }],
        })(<Input />)}
      </FormItem>
    </Form>
  );
});

class Demo extends React.Component {

  handleFormChange = (changedFields) => {

        <pre className="language-bash">
          {JSON.stringify(fields, null, 2)}

    );
  }
}

ReactDOM.render(<Demo />, document.getElementById('container'));
