Can't remove div with Else statement

Hi,

I’m am trying to add a loop after the content on several pages.

I have managed to do this by adding this code to the bottom of my Page.php…

<div class="row-fluid" id="blog">

<?php
  if ( is_page( 'ski' ) ) {
    query_posts('cat=10');
}
 elseif ( is_page( 'gear' ) ) {
      query_posts('cat=6');
}
elseif ( is_page( 'published' ) ) {
      query_posts('cat=7');
}
elseif ( is_page( 'behind-the-scenes' ) ) {
      query_posts('cat=9');
}
else{
}
?>
<script type="text/javascript">$('#blog').hide()</script>
<?php
}
?>

 <section class="<?php echo $myThemes_layout -> contentClass(); ?> list-view">
<?php
	if ( have_posts() ) {
	 while ( have_posts() ) {
	 the_post();
	get_template_part( 'cfg/templates/view/list-view' );
	}
	}
		else{
                        }

 		get_template_part( 'cfg/templates/pagination' );
                    ?>
                </section>

</div>

Nowww I need to figure out how to remove the blog if the page is not one of the specified… AKA falls into the “else{}” category.

I tired to do this by adding this…

else{
$('#blog').hide()
}

but it doesn’t seem to work. Any ideas??
