我正在使用 antd 模板进行表单设计。提交表单后，输入值没有被清除。
我试过this.props.form.resetFields()它不工作得到以下错误
Unhandled Rejection (TypeError): Cannot read property 'resetFields' of undefined

export default withRouter(Registration);最佳答案
首先你不需要使用this.props .当您像这样导入时。如果您仍然需要 Prop 形式，您需要Form.create Ant 的api。 form没有从 Form 导出api。更好的方法是你已经定义了 ref。通过以下方式访问表单值:
formRef = React.createRef();
<Form
{...formItemLayout}
name="register"
scrollToFirstError
onFinish={() => this.submitForm()}
ref={this.formRef}
>
//submit form
submitForm = () => {
console.log("Form submitted:", this.formRef, Form);
this.formRef.current.resetFields();
};
