Question

我添加了一个带有插件的加载按钮＆＃34;轻松加载更多＆＃34; （https://wordpress.org/plugins/easy-load-more/）。该按钮工作正常，但即使没有更多帖子显示，它仍会显示。如果没有任何东西可以加载，我希望它不显示。有没有人有什么建议？提前谢谢。

frontend.js

＆＃13;

;(function ($) {

$(document).ready(function() {
$('.elm-button').on('click', function (e) {
e.preventDefault();

var $that = $(this),
url = $that.attr('data-href'),
nextPage = parseInt($that.attr('data-page'), 10) + 1,
maxPages = parseInt($that.attr('data-max-pages'), 10);

$that.addClass('is-loading');

if (url.indexOf('?') > 0) {
url += '&';
} else {
url += '?';
}

url += 'paged=' + nextPage;

$.ajax({
type : 'POST',
url : url,
dataType: 'text'
}).done(function (data) {

$that.removeClass('is-loading');

if ($(elm_button_vars.wrapper).length) {
$(elm_button_vars.wrapper).append($($.parseHTML(data)).find(elm_button_vars.wrapper).addBack(elm_button_vars.wrapper).html());
} else {
console.log('Please update Easy Load More settings with post list wrapper selector.');
}

if ( nextPage == maxPages ) {
$that.remove();
} else {
$that.attr('data-page', nextPage);
}

}).fail(function () {
console.log('Ajax failed. Navigating to ' + url + '.');
window.location.href = url;
});

return false;
});
});

}(jQuery));

和我的front-page.php

＆＃13;

<?php

get_header();
get_template_part ('inc/carousel');

$the_query = new WP_Query( [
    'posts_per_page' => 14,
    'paged' => get_query_var('paged', 1)
] );

if ( $the_query->have_posts() ) { ?>
    <div id="ajax">
    <?php
    $i = 0;
    while ( $the_query->have_posts() ) { $the_query->the_post();

        if ( $i % 7 === 0 ) { // Large post: on the first iteration and every 7th post after... ?>
        <article <?php post_class( 'col-md-12' ); ?>>
            <?php the_post_thumbnail('large-thumbnail'); ?>

Answer 1

在.done()中，您需要检查是否因为ajax调用而收到了更多数据。如果没有，则不要show。目前，您没有定义该检查，因此行为。

.done(function (data) {

    $that.removeClass('is-loading');

   // CHECK if data contains something?
   if(YES) {
       if ($(elm_button_vars.wrapper).length) {
          $(elm_button_vars.wrapper).append($($.parseHTML(data)).find(elm_button_vars.wrapper).addBack(elm_button_vars.wrapper).html());
       }
       else {
          console.log('Please update Easy Load More settings with post list wrapper selector.');
       }

      if ( nextPage == maxPages ) {
          $that.remove();
      }
      else {
         $that.attr('data-page', nextPage);
      }
   }
})

如果没有任何东西要加载，请隐藏更多负载
