Framework7表单数据

本文概述

有一些表格数据方法使使用表格变得容易。请参见两种表单数据方法:

表单到JSON formToJSON()方法用于将所有表单字段值转换为JSON。

来自JSON的表单:formFromJSON方法用于根据JSON数据填充表单。

表单到JSON

Framework7提供了一种myApp.formToJSON(form)方法, 用于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, 它是HTMLElement或必须转换为JSON的形式的字符串。此参数是必需的, 并且此方法返回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在JSON中显示为数组。

让我们以一个示例来演示在Framework7中将表单用于JSON的方法:

JSON示例中的表格

Framework7通过使用以下方法帮助你根据JSON填写表单:

myApp.formFromJSON(form, formData):此方法接受两个参数:

  • 形式:它是HTMLElement或形式的字符串, 必须转换为JSON。这是一个必需的参数。
  • formData:这是具有JSON格式的表单数据的对象。这是一个必需的参数。

让我们以一个示例来演示在Framework7中使用JSON格式的情况:

<!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" />
