还是拿代码来讲吧，详情见注释
子组件
import React, { Component } from 'react';
import { Form, Input } from 'antd';
const FormItem = Form.Item;
class Forms extends Component{
getItemsValue = ()=>{ //3、自定义方法，用来传递数据(需要在父组件中调用获取数据)
const valus= this.props.form.getFieldsValue(); //4、getFieldsValue：获取一组输入控件的值，如不传入参数，则获取全部组件的值
return valus;
}
render(){
const { form } = this.props;
const { getFieldDecorator } = form; //1、将getFieldDecorator 解构出来，用于和表单进行双向绑定
return(
<>
{getFieldDecorator('name')( //2、getFieldDecorator 的使用方法，这种写法真的很蛋疼
)}
{getFieldDecorator('age')(
)}
{getFieldDecorator('address')(
)}
>
)
}
}
export default Form.create()(Forms); //创建form实例
getFieldDecorator 的具体参数见官方文档
父组件
import React, { Component } from 'react';
import { Modal } from 'antd';
import Forms from './Forms'
export default class Modals extends Component {
handleCancel = () => {
this.props.closeModal(false);
}
handleCreate = () => {
console.log(this.formRef.getItemsValue()); //6、调用子组件的自定义方法getItemsValue。注意：通过this.formRef 才能拿到数据
this.props.getFormRef(this.formRef.getItemsValue());
this.props.closeModal(false);
}
render() {
const { visible } = this.props;
return (
visible={visible}
title="新增"
okText="保存"
onCancel={this.handleCancel}
onOk={this.handleCreate}
>
wrappedComponentRef={(form) => this.formRef = form} //5、使用wrappedComponentRef 拿到子组件传递过来的ref(官方写法)
/>
);
}
}
官方文档
class CustomizedForm extends ponent { ... }
// use wrappedComponentRef
const EnhancedForm = Form.create()(CustomizedForm);
this.form = form} />
this.form // => The instance of CustomizedForm
