Form data to Object jQuery
Example：
<form id="contact">
<input name="user[email]" value="jsmith@example.com">
<input name="user[pets][]" type="checkbox" value="cat" checked>
<input name="user[pets][]" type="checkbox" value="dog" checked>
<input name="user[pets][]" type="checkbox" value="bird">
<input type="submit">
</form>
$('form#contact').serializeObject();
//=> {user: {email: "jsmith@example.com", pets: ["cat", "dog"]}}
$('form#contact').serializeJSON();
//=> '{"user":{"email":"jsmith@example.com","pets":["cat","dog"]}}
'
