In jQuery, suppose you have an element of some kind that you’re hiding and showing, using .hide(), .show() or .toggle(). How do you test to see if that element is currently hidden or visible on the screen?

 // Checks for display:[none|block], ignores visible:[true|false]
 $(element).is(":visible") 

You can use the “hidden” and “visible” selectors.

 $('element:hidden')
 $('element:visible')
                <div class="pagination">               
                  <span class="prev"></span>
                  <span class="num" id="1">1</span> 
                  <span class="num_active" id="2">2</span> 
                  <span class="num" id="3">3</span> 
                  <span class="num" id="4">4</span> 
                  <span class="num" id="5">5</span> 
                  <span class="num" id="6">6</span> 
                  <span class="next"></span>
                 </div>
  $('.pagination span').click(function(){
	$(".pagination span").removeClass("num_active").addClass("num"); 
	$(".pagination span:first").removeClass("num").addClass('prev');
	$(".pagination span:last").removeClass("num").addClass('next');
        $(this).addClass("num_active"); 
  });

Please Note the Last 2 which accounts for the array argument args as num1 and num2 does not account for array arguments

If the Code is like below then it would have been a error

  public void argCount(int num1, int num2, int... args)
