我正在使用 redux-form 加载编辑表单的初始数据似乎让我感到困惑，但提交时未验证数据。我已经设法将数据传递并加载到字段中，但似乎没有加载到表单 Prop 等中。请查看以下代码，如果需要更多信息，请告诉我。

    }, dispatch);
};


NewBayanForm = connect(mapStateToProps, mapDispatchToProps) (newBayanFormAdmin_reduxformObj(NewBayanForm));

export default NewBayanForm;

最佳答案

尝试 initialValues 以获得更多 details

在 reduxform 内部:

export default NewBayanForm = reduxForm({ form: 'NewBayanForm', initialValues: {
  name: "abc",
  email: "abc@gmail.com",
  phoneNo: "1234567890"
} })(NewBayanForm)

或

<NewBayanForm initialValues={yourObject} />
