javascript - Get the posts count in JS (Wordpress) -

i have site on wp.

i'm using ajax show posts. on click on 'more' button appears 2 more posts. , i'm trying hide button when of posts shown. go wrong.

i don't understand how take posts count js (it's variant), because construction var posts_count = "<?php echo $posts_count; ?> doesn't work - gives string!

js

$(function () {    var posts = 2; //posts shown   var posts_offset = 2;      $("#load-post").click(function (e) {     e.preventdefault();       $.ajax({       type: "get",       url: "/wp-admin/admin-ajax.php",       data: ({         action: 'loadmore',         posts_offset: posts_offset       }),       success: function (data) {         $('.news #content').append(data);         posts_offset += 2;        }     });     });   }); 

php

function loadmore() {        $posts_count = wp_count_posts()->publish;       $posts_offset = $_get['posts_offset'];       // $_get variables sorted out      // setup query want     query_posts( array( 'posts_per_page' => 2, 'offset'=> $posts_offset ) );      // initialsise output     $output = '';      // loop     while (have_posts()) : the_post();           ?><div class="col-lg-6 col-md-6 col-sm-12 col-xs-12 news-item">               <div class="news-date">                 <?php the_time($format = "j f y") ?>               </div>               <div>                 <h3><?php the_title() ?></h3>                 <p><?php the_content() ?></p>               </div>             </div><?php      endwhile;    if ($posts_count - ($posts_offset + 2) <= 0) { ?>       <script>$("#load-more").hide();</script>     <?php }       // reset query     wp_reset_query();      die($output);  } 

this code works, doesn't work part of hiding button

change code follows:

in php

<script>function hideloadmore(){$("#load-more").hide();}</script> 

and in js

success: function (data) {     $('.news #content').append(data);     posts_offset += 2;     if(hideloadmore) {          hideloadmore();      }   }
