详谈表单格式化插件jquery.serializeJSON

// returns =>
{
fullName: "Mario Izquierdo",

address: {
city: "San Francisco",
state: {
name: "California",
abbr: "CA"
}
},

jobbies: ["code", "climbing"],

projects: {
'0': { name: "serializeJSON", language: "javascript", popular: "1" },
'1': { name: "tinytest.js", language: "javascript", popular: "0" }
},

selectOne: "rock",
selectMultiple: ["red", "blue"]}

serializeJSON方法返回一个JS对象，并非JSON字符串。可以使用 JSON.stringify 转换成字符串（注意IE8兼容性）。

 var jsonString = JSON.stringify(obj);

指定数据类型

获取到的属性值一般是字符串，可以通过HTML指定类型 : type 进行强制转换。

<form>
  <input type="text" name="notype"      value="default type is :string"/>
  <input type="text" name="string:string"  value=":string type overrides parsing options"/>
  <input type="text" name="excluded:skip"  value="Use :skip to not include this field in the result"/>
  <input type="text" name="number[1]:number"      value="1"/>
  <input type="text" name="number[1.1]:number"     value="1.1"/>
  <input type="text" name="number[other stuff]:number" value="other stuff"/>
  <input type="text" name="boolean[true]:boolean"   value="true"/>
  <input type="text" name="boolean[false]:boolean"   value="false"/>
  <input type="text" name="boolean[0]:boolean"     value="0"/>
  <input type="text" name="null[null]:null"      value="null"/>
  <input type="text" name="null[other stuff]:null"   value="other stuff"/>
  <input type="text" name="auto[string]:auto"     value="text with stuff"/>
  <input type="text" name="auto[0]:auto"        value="0"/>
  <input type="text" name="auto[1]:auto"        value="1"/>
  <input type="text" name="auto[true]:auto"      value="true"/>
  <input type="text" name="auto[false]:auto"      value="false"/>
  <input type="text" name="auto[null]:auto"      value="null"/>
  <input type="text" name="auto:auto"      value="[1, 2, 3]"/>
  <input type="text" name="array[empty]:array"     value="[]"/>
  <input type="text" name="array:array"     value="[1, 2, 3]"/>
  <input type="text" name="object[empty]:object"    value="{}"/>
  <input type="text" name="object[dict]:object"    value='{"my": "stuff"}'/>
</form>

$('form').serializeJSON();
// returns =>
{
  "notype": "default type is :string",
  "string": ":string type overrides parsing options",
  // :skip type removes the field from the output
