Framework7表单存储用于自动在Ajax加载的页面上存储和解析表单数据。每次再次加载页面时, Framework7都会解析此数据并自动填写表单。
表单存储有两种类型：
启用表单存储：如果要启用表单存储, 则必须向表单添加store-data类和id属性。
表单存储JavaScript API：可以使用JavaScript API实现表单存储。
启用表格存储示例
让我们以显示表单存储为例, 该存储存储在表单中输入的数据, 并在重新加载页面时自动解析表单数据。

表单存储JavaScript API示例
在Form Storage JavaScript API中, 所有表单数据都通过键存储在本地存储中。有一些方法可以使用表单数据管理这些本地存储密钥。
| 指数 | 类 | 描述 |
|---|---|---|
| 1) | myApp.formGetData(formId) | 当你打开动画时, 将触发此事件。 |
| 2) | myApp.formDeleteData(formId) | 动画的打开完成后, 将触发此事件。 |
| 3) | myApp.formStoreData（formId, formJSON） | 当你关闭动画时, 将触发此事件。 |
例
让我们以一个示例来演示表单存储JavaScript API的用法, 该API将数据存储在Framework7的本地存储中。
