#### 表单数据存储于上层组件
|
|
|
通过使用 `onFieldsChange` 与 `mapPropsToFields`，可以把表单的数据存储到上层组件。
|
|
|
**注意：**
|
|
|
`mapPropsToFields` 里面返回的表单域数据必须使用 `Form.createFormField` 包装。
|
|
|
如果你使用`Form.create`，上层组件传递的属性，必须在`Form.create({ props: ...})`的props中声明。
|
|
|
如果使用`this.$form.createForm`，你可以使用任何数据，不仅仅局限于上层组件的属性。

#### Store Form Data into Upper Component
|
|
|
We can store form data into upper component.
|
|
|
**Note:**
|
|
|
If you use `Form.create`. You must wrap field data with `Form.createFormField` in `mapPropsToFields`.
|
|
|
The properties passed by the upper component must be declared in the props of `Form.create({ props: ...})`.
|
|
|
But if you use `this.$form.createForm`, You can use any data, not just the properties of the upper components.
