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），或者如果可选的 getHash 计算结果为真，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 的计算结果是否为真，结果要么是 {name: “johnny”, color: “blue”} 形式的对象，要么是 “name = johnny&color = blue” 形式的字符串，适合用于 Ajax 请求中的参数。
语法
formElement.serialize([getHash = false]);返回值
它返回一个字符串对象。
这里有两个关于它如何工作的提示。有关详细信息，请查看下面的示例。
$('example').serialize()
// 'username = sulien&age = 22&hobbies = coding&hobbies = hiking'
$('example').serialize(true)
// {username: 'sulien', age: '22', hobbies: ['coding', 'hiking']}例子
