jquery - Get all matching elements in nearest parent -

when click on 1 of buttons, <p>s in encapsulating div should given yellow background.
ideally see $(this), parent , matching elements selector in jquery selector. update: sorry did not make request clear.
see selectors of parent div, elements select in parent , $(this) in select clause.
want <p> elements .left div, can extend selector clause this
$("p", ".left") - gets <p> in .left
in case, hold of .left using $(this), while "is" button. should in lines of
$("p", $(this).closest("body > div"))

heres jsfiddle
code.

    <style>     div p.painted {         background-color: #ff0;     }     </style>     <div class="left">         <div class="actions">             <div class="ui">                 <div class="colors">                     <button class="paint">paint yellow!</button>                 </div>             </div>         </div>         <p>             lorem ipsum          </p>         <p>             lorem ipsum dummy text of printing , typesetting industry. lorem ipsum has been industry's standard dummy text ever since 1500s, when unknown printer took galley of type , scrambled make type specimen book. has survived not 5 centuries, leap electronic typesetting, remaining unchanged. popularised in 1960s release of letraset sheets containing lorem ipsum passages, , more desktop publishing software aldus pagemaker including versions of lorem ipsum.         </p>     </div>     <div class="right">         <div class="actions">             <div class="ui">                 <div class="colors">                     <button class="paint">paint yellow!</button>                 </div>             </div>         </div>         <p>             lorem ipsum          </p>         <p>             lorem ipsum dummy text of printing , typesetting industry. lorem ipsum has been industry's standard dummy text ever since 1500s, when unknown printer took galley of type , scrambled make type specimen book. has survived not 5 centuries, leap electronic typesetting, remaining unchanged. popularised in 1960s release of letraset sheets containing lorem ipsum passages, , more desktop publishing software aldus pagemaker including versions of lorem ipsum.         </p>     </div>      <script>     $(function(){         $(".paint").click(paintit);     });      function paintit(){         $(this).closest("p").addclass("painted");     }     </script> 

you can use siblings() instead of closest select <p>s. here's updated fiddle.
