Framework7 - Form 表单转 JSON

描述

Framework7 允许您使用以下方法将所有表单字段值转换为 JSON −

• myApp.formToJSON(form) − 此方法接受 form 作为参数，该参数是必须转换为 JSON 的 HTMLElement 或 string 表单。此参数是必需的，此方法返回 JSON 数据。

每个输入都必须具有 name 属性，否则其值不会出现在 JSON 中。多个选择和复选框将作为数组出现在 JSON 中。

示例

以下示例演示了在 Framework7 中使用表单转 JSON −

输出

让我们执行以下步骤来查看上述代码的工作原理 −

• 将上述 HTML 代码保存为服务器根文件夹中的 forms_to_json.html 文件。

• 以 http://localhost/forms_to_json.html 的形式打开此 HTML 文件，输出如下所示。

• 当您在表单中输入详细信息并单击"获取表单数据"按钮时，所有字段值都将转换为 JSON 格式并显示给您。
