我有一个使用离子React动态构建的表单,是的,用于验证,这是基于来自API的信息完成的,但我有一个问题,如果我没有选择单选按钮,当我按提交单选按钮变得不可点击,这意味着我永远无法摆脱错误。
我在这里创建了一个硬编码表单的示例,而不是动态填充的表单,如果您单击"保存"而不执行任何操作,则无法选择单选按钮,但我无法解决我的问题来自哪里。

以下是无法正常工作的主要代码部分:

  IonItem,
  IonLabel,
  IonRadio,
  IonButton,
  IonContent,
  IonPage,
  setupIonicReact,
  IonInput
} from "@ionic/react";

export default function App() {

  } = useForm({

  });

  const onSubmit = (data: any) => {

你的问题是你应该传入onChange函数js事件。在onIonChange中修改了具有自定义属性的事件。但是你实际上传递了一个值给函数,而不是一个事件。
您可以在dock中找到onIonChange或setValue中的标准js事件

<IonRadioGroup
    {...field}
    onIonChange={
    (event) => {
       setValue('q7', event.detail.value)
      }
    }
