如何写jquery里面的以json格式获取表单数据？
方法如下：
将Form的数据转化成Javascript的Json对象
Jquery的serializeArray 方法已经可以实现将Form的数据序列化为一个数组，只要稍微在这个方法的基础上做些修改即可。

$

serializeObject
=
function
(
)
{
var
o
=
{
}
;
var
a
=
this
.
serializeArray
(
)
;
$
.
each
(
a
,
function
(

{
if
(
o
[
this
.
name
]
!==
undefined
)
{
if
(
!
o
[
this
.
name
]
.
push
)
{
o
[
this
.
name
]
=
[
o
[
this
.
name
]
]
;
}
o
[
this
.
name
]
.
push
(
this
.
value
||
''
)
;
}
else
{
o
[
this
.
name
]
=
this
.
value
||
''
;
}
}
)
;
}

$(“form”).serializeArray() 不行吗？ 还需要map下
serializeArray() 方法序列化表单元素，返回 JSON 数据结构数据。如：
[
{name: ‘firstname’, value: ‘Hello’},
{name: ‘lastname’, value: ‘World’},
{name: ‘alias’}, // 值为空
]
