Prototype - Form serialize() 方法
此方法用于将表单数据序列化为适合 Ajax 请求的字符串(默认行为)，或者，如果可选 getHash 计算结果为 true，则为对象哈希，其中键是表单控件名称，值是数据。
根据可选参数 getHash 是否计算为 true，结果要么是形式为 {name: "johnny", color: "blue"} 的对象，要么是形式为"name = johnny&color = blue"的字符串，适合 Ajax 请求中的参数。
语法
formElement.serialize([getHash = false]);
返回值
它返回一个 String 对象。
以下是有关其工作原理的两个提示。有关详细信息，请参阅下面的示例。
$('example').serialize()
// 'username = sulien&age = 22&hobbies = coding&hobbies = climbing'
$('example').serialize(true)
// {username: 'sulien', age: '22', hobbies: ['coding', 'hiking']}
