How to find all disabled fields under body tag and addClass("disabeldFields") using jquery. Below is my code :

HTML :

```
<input id="btnOk" value="Ok" type="button"/>
<input id="text1" type="text" disabled/>
<input id="text2" type="text"/>
<input id="text3" type="text" disabled/>

```

Jquery : 

```
$("#btnOk").click(function(){
    $(this).closest("body").find($(*).prop('disabled')).addClass("disabeldFields");
});

```

Its not working. How can I do it ?
Thanks in Advance.
