描述 (Description)
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HTMLElement或必须转换为JSON的表单string 。 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，否则其值不会出现在JSON中。 多个选择和复选框将在JSON中显示为数组。
例子 (Example)
以下示例演示了在Framework7中使用表单到JSON -
<!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"
