How to call hidden div tags by ID or Class in Jquery.

Example:

HTML:

<div id="off" style="display:none">
      <p> Show me </p>
</div>

<button id="load">Load Selected DIV</button>

Script:

<script type="text/javascript"> 
$(function(){

$("#load").click(function(e){ 
 e.preventDefault();
 $("#off:hidden").slice(0, 10).show(); 
 if ($("#off:hidden").length == 0){ 
 return false;
 }
 });
});
</script>
