I have following object:

```
$("input:checkbox:checked")
[
<input class=​"li_checker" type=​"checkbox" category_uid=​"1.3" category_language=​"da">​, 
<input class=​"li_checker" type=​"checkbox" category_uid=​"1.3.1" category_language=​"da">​
]

```

If there is any helper in jQuery which allows me to get value of "category\_uid" for all elements and returns it as the another array? Expected result:

```
["1.3", "1.3.1"]

```
