特别说明一下，在选取用户界面，使用的是checkbox控件，得到选中的checkbox，是使用下面的实例代码：
|
1
2
|
<
input
id
=
"checkbox1"
type
=
"checkbox"
checked>
<
input
id
=
"checkbox2"
type="checkbox>
|
|
1
2
3
4
5
|
$(
"#checkbox1"
).is(
":checked"
)
// true
$(
"#checkbox2"
).is(
":checked"
)
// false
//注意不是使用下面的方法
$(
"#checkbox1"
).attr(
"checked"
)
// checked
$(
"#checkbox2"
).attr(
"checked"
)
// undefined
