Framework7 - 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 的表单的HTMLElement或字符串。此参数是必需的，此方法返回 JSON 数据。
每个输入必须具有name属性，否则其值将不会出现在 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 的方法：
<!DOCTYPE html>
<html>
<head>
<meta name = "viewport" content = "width = device-width, initial-scale = 1,
maximum-scale = 1, minimum-scale = 1, user-scalable = no, minimal-ui" />
<meta name = "apple-mobile-web-app-capable" content = "yes" />
<meta name = "apple-mobile-web-app-status-bar-style" content = "black" />
<title>Checkboxes group</title>
<link rel = "stylesheet"
href = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/css/framework7.ios.min.css" />
<link rel = "stylesheet"

var $$ = Dom7;
$$('.form-to-json').on('click', function() {
var formData = myApp.formToJSON('#my-form');
alert(JSON.stringify(formData));
});

输出
让我们执行以下步骤来了解上面代码的工作原理：
将上面给定的 HTML 代码保存为forms_to_json.html文件到您的服务器根目录。
以 https:///forms_to_json.html 的方式打开此 HTML 文件，输出将如下所示。
当您在表单中输入详细信息并点击“获取表单数据”按钮时，所有字段值将转换为 JSON 格式并显示给您。
