如何使用 React Hooks 获取 Antd Form 的值?

How to get the value of Antd Form with React Hooks?

下面是TextareaItemantd-mobile的例子,
我想用 React Hooks 重写它,
这是我的半成品代码:

import React, { useState, useEffect} from "react"
import { List, TextareaItem } from 'antd-mobile';
import { createForm } from 'rc-form';


function TextareaItemExample {

  useEffect(() => {
    //this.autoFocusInst.focus();
  });

  return (
    <div>
      <List renderHeader={() => 'Customize to focus'}>
        <TextareaItem
          title="title"
          placeholder="auto focus in Alipay client"
          data-seed="logId"
          ref={el => this.autoFocusInst = el}
          autoHeight
        />
        <TextareaItem
          title="content"
          placeholder="click the button below to focus"
          data-seed="logId"
          autoHeight
        />
      </List>
    </div>
  );
}

const TextareaItemExampleWrapper = createForm()(TextareaItemExample);

export default TextareaItemExampleWrapper;

问题:
1、如何用React Hooks获取TextareaItem的值?获取后我会发送ajax请求 values.There是一个自定义的hook react-use-form-state,但是它作用于html form,如何在 Antd Form 上做同样的事情?

2、如何修改函数组件中的句子this.autoFocusInst.focus();

要使用 ref,您可以使用 useRef 挂钩。通过提供第二个参数作为空数组,也可以使 useEffect 的行为类似于 componentDidMount。使用受控的 TextAreaItem,您也可以获得状态中的值。

import React, { useState, useEffect, useRef} from "react"
import { List, TextareaItem } from 'antd-mobile';
import { createForm } from 'rc-form';


function TextareaItemExample {

  const [title, setTitle] = useState();
  const [content, setContent] = useState();

  const handleTitleChange = (value) => {
      setTitle(value);
  }
  const handleContentChange = (value) => {
      setContent(value)
  }
  const autoFocusInt = useRef();
  useEffect(() => {
    autoFocusInst.current.focus();
  }, []);

  return (
    <div>
      <List renderHeader={() => 'Customize to focus'}>
        <TextareaItem
          title="title"
          value={title}
          onChange={handleTitleChange}
          placeholder="auto focus in Alipay client"
          data-seed="logId"
          ref={autoFocusInst}
          autoHeight
        />
        <TextareaItem
          title="content"
          value={content}
          onChange={handleContentChange}
          placeholder="click the button below to focus"
          data-seed="logId"
          autoHeight
        />
      </List>
    </div>
  );
}

const TextareaItemExampleWrapper = createForm()(TextareaItemExample);

export default TextareaItemExampleWrapper;

如果您不将其设为受控输入,您可能可以使用 ref.
