hello i use load more functionality for tab. i crete this code its true or false?

<div class=”showall”> Load more </div>

<script>
function loadmore_portfolio(ref){

var selected_tab = $(‘li’).find(‘a.selected’).attr(‘id’);

var list = [];
$(‘#apendata-‘+selected_tab+’ li’).each(function() {
var id = $(this).attr(‘id’).split(‘-‘)[1];
list.push(id);
//alert(id);
});
$.ajax({

success:function(resp){
if(resp.trim()==”){
//$(‘.showall’).css(‘display’,’none’);

$exclude_post = $_REQUEST[‘list’];
$tax = “portfolio_taxonomy”;

//$data = get_term_by($field, $value, $taxonomy);
$termname = get_term_by( ‘id’, $selected_tab, $tax );
//echo “

	$term= get_term( $selected_tab, 'portfolio_taxonomy' );

	$argssss = new wp_query(array(
                            'post_type' => 'portfolio',
                            'posts_per_page' => 2,
                            "$tax" => $termname->slug,
							'order' => 'ASC',
                            'orderby' => 'date',
							'post__not_in' => $exclude_post,
                            'post_status' => 'publish'

                        ));

 	while($argssss->have_posts()): $argssss->the_post();
