JQuery AJAX将空参数传递给我的函数吗？

我正在尝试用ajax做一个简单的表单提交（这样页面就不会刷新）

functions.php

add_action(\'wp_ajax_send_projectmessage\', \'send_projectmessage\');
function send_projectmessage($projectid, $userid, $message) {
    global $wpdb;
    $wpdb->insert(\'tbl_messages\', array(
        \'project_id\' => $projectid,
        \'user_id\' => $userid,
        \'message_body\' => $message
    ));
    echo \'success?\'; //this shows up in console.log but 3 parameters are empty
    wp_die();
}

js:

$(\'#form-pm\').on(\'submit\',function(e) {

    e.preventDefault();

    //hardcode stuff for testing
        var testdata = { 
            \'action\': \'send_projectmessage\',
            \'projectid\': \'71\', 
            \'userid\': \'1\', 
            \'message\': \'voila\' 
        };

        var ajaxRequest =
        $.ajax({
            url: admin_ajax.ajax_url,
            type: \'post\',
            data: testdata
        });

        ajaxRequest.done(function(data) { console.log(data); });
        ajaxRequest.fail(function(jqXHR) { alert(\'You are fail. \' + jqXHR); });      
});

管理ajax。php连接正确。我的错误。日志显示send_projectmessage 正在调用函数，但参数为空。我错过什么了吗？从昨天起我就一直在拉扯头发。

如何通过AJAX“加载更多”帖子？

关于分类法{name}。php模板用于我的“组织”分类法，我目前显示的帖子数量有限，按分类法的每个术语“格式”分组。如果可用帖子的数量超过了可显示的数量，我现在想启用基于AJAX的加载更多帖子。我已经关注了无数关于这个主题的教程和StackExchange问题，但有些东西仍然没有点击。例如，我实现了Misha Rudrastyh\'s \"Load More\" button, 但代码不会加载任何帖子。我迷路了，快要放弃了。我有一个帖子块，上面有这样一个“更多”链接，准备好了，等待着。。。这对应于一个分类
