WordPress提交评论ajax翻页的效果会很大的提高用户体验度，虽然我们一般的个人WordPress博客评论也不会有很多，但是用户体验至上嘛，所以WordPress主题站小编为大家分享WordPress实现提交评论ajax翻页效果教程，希望能给大家能用得上。
最终效果如下图所示：
在使用AJAX加载评论时，需要在后台设置-评论设置，其中每页显示评论数量可以根据你的需要自定义。
WordPress纯代码实现提交评论ajax翻页效果
添加“加载更多”按钮
首先我们在主题中查找评论分页功能 paginate_comments_links()函数，并将其替换为以下代码。若找不到此函数，请在代码<ol class=”comment-list”>…</ol>后面放置代码。
$cpage = get_query_var(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’cpage\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’) ? get_query_var(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’cpage\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’) : 1;
if( $cpage > 1 ) {
echo \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'<div class=\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”comment_loadmore\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\”>More comments</div>
<script>
var ajaxurl = \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ . site_url(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’wp-admin/admin-ajax.php\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’) . \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,
parent_post_id = \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ . get_the_ID() . \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,
cpage = \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ . $cpage . \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’
</script>\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’;
}
由于默认显示最后的评论页面，$cpage 所以等于注释页面的最大数量。条件 if( $cpage > 1 ) {意味着两件事情同时发生 – 在下列情况下输出加载更多按钮和脚本。
无限加载 jQuery代码
jQuery(function($){
//加载更多按钮点击事件
$(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’.comment_loadmore\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’).click( function(){
var button = $(this);
//减少当前评论页面的值
cpage – ;
$.ajax({
url : ajaxurl,
data : {
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’action\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’: \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’cloadmore\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’post_id\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’: parent_post_id,//当前文章
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’cpage\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ : cpage,//当前评论页
},
type : \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’POST\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,
beforeSend : function ( xhr ) {
button.text(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’加载中…\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’);
},
success : function( data ){
if( data ) {
$(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ol.comment-list\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’).append( data );
button.text(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’加载更多\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’);
//如果最后一页，则删除按钮
if ( barley.cpage == 1 )
button.remove();
} else {
button.remove();
}
}
});
return false;
});
});
这里减少 cpage 了的值，因为评论页以降序显示。接着就是加载这个 JQ 到页面，这里就不详细说了。
实现功能
最后我们在 functions.php 中插入下面代码：
add_action(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’wp_ajax_cloadmore\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’comments_loadmore_handler\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’); // wp_ajax_{action}
add_action(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’wp_ajax_nopriv_cloadmore\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’, \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’comments_loadmore_handler\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’); // wp_ajax_nopriv_{action}
function comments_loadmore_handler(){
global $post;
$post = get_post( $_POST[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’post_id\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’] );
setup_postdata( $post );
wp_list_comments( array(
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’avatar_size\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => 100,
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’page\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => $_POST[\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’cpage\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’],
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’per_page\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => get_option(\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’comments_per_page\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’),
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’style\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ol\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’short_ping\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => true,
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’reply_text\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’ => \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’回复\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\’,
) );
die;
}
至此，WordPress纯代码实现提交评论ajax翻页效果的教程就结束了，看到这里你应该也已经知道如何实现这个功能了。
