在Form.item不单独绑定value 值和onChange方法时使用
1、Button在Form内部,加上 htmlType="submit"属性触发Form表单onFinishsh事件
import React from "react"; import { Form, Button } from "antd"; export default function Page({ route, location }) { const [form] = Form.useForm(); const initialValues = { input: "", }; const handSubmit = (value) => { console.log("Form内部触发:", value); }; return ( <Form style={{ margin: 40 }} form={form} initialValues={initialValues} onFinish={handSubmit} > <Form.Item name="input"> <input /> </Form.Item> <Button type="primary" htmlType="submit" style={{ margin: 40 }}> 提交 </Button> </Form> ); }
2、button在Form外,根据表单自带getFieldsValue方法获取
const getFormValue = () => { console.log("form.getFieldsValue: ", form.getFieldsValue()); }; return ( <> <Form style={{ margin: 40 }} form={form} initialValues={initialValues} > <Form.Item name="input"> <input /> </Form.Item> </Form> <Button type="primary" style={{ marginLeft: 40 }} onClick={getFormValue} > 提交 </Button> </> );
3、给Form绑定id,button 设置 form=‘id’ 和 htmlType=“submit”,可在Form外部触发onFinish事件
const handSubmit = (value) => { console.log("Form外部触发:", value); }; return ( <> <Form id="form" style={{ margin: 40 }} form={form} initialValues={initialValues} onFinish={handSubmit} > <Form.Item name="input"> <input /> </Form.Item> </Form> <Button type="primary" style={{ marginLeft: 40 }} form="form" htmlType="submit" > 提交 </Button> </> );
