Php modx getResources-抵销/限额问题？

我已经设置好了，这样一个主博客页面会显示最初的3篇文章，当完全加载时会显示标签

            [[!getResourcesTag? 
                &element=`getResources` 
                &elementClass=`modSnippet`
                &tpl=`blog-item`
                &tplFirst=`blog-item-featured`
                &limit=`3`
                &hideContainers=`1` 
                &parents=`5` 
                &tagKey=`blog-tags`
                &includeTVs=`1`
                &tvPrefix=``
            ]]

显示的最初3篇文章在主登录页（最近的第一篇）上按日期顺序排序，例如第1条、第2条和第3条

点击显示的3篇文章下方的“更多文章”按钮，无限滚动分页（已设置）开始

<button class="load-more" data-parent="5" data-current-page="1">More Posts</button>

我一直在玩弄参数&试图修改处理

offset

的代码，但似乎无法理解

一些帮助会很好。

添加了更新的代码

不久前，我做了类似的事情，几乎完全是事实[一定是谷歌搜索到的]

我的初始getResources调用中唯一的区别是我使用了0的偏移量

<div id="posts">
<!-- get first few articles -->
[[!getResources?
     &parents=`10,22`
     &depth=`999`
     &limit=`6`
     &offset=`0`
     &includeTVs=`1`
     &processTVs=`1`
     &includeContent=`1`
     &tpl=`infiniteHomePageTpl`
     &sortby=`publishedon`
     &showHidden=`1`
     &hideContainers=`1`
]]

</div>

<button id="scroller" class="btn btn-primary load-more" data-parents="10,22" data-offset="6" data-posts="3">Show More Articles</button>
<button id="scolltotop" class="btn btn-primary scrollToTop" style="display:none;">Back to Top</button>

[[！获取资源？

为了简单起见，下面是代码片段和js：

<?php
    $output = array(
      'status' => 'success',
      'msg' => 'message',
      'data' => 'blaaaaaaaah',
      'lastpost' => FALSE,
    );

    $properties = $scriptProperties['data'];

    $modx->log(modX::LOG_LEVEL_ERROR,'Running processor: ajax.generic, scriptProperties = '. print_r($properties, TRUE));

    $limit  = $properties['limit'];
    $parents = $properties['parents'];
    $tpl    = $properties['tpl'];
    $offset = $properties['offset'];
    $depth = $properties['depth'];
    $sortby = $properties['sortby'];
    $debug = $properties['debug'];
    $showHidden = $properties['showHidden'];
    $hideContainers = $properties['hideContainers'];

    $modx->log(modX::LOG_LEVEL_ERROR, 'tpl = ' . $tpl);

    $posts = $modx->runSnippet('getResources', array(
        'parents'       => $parents,
        'depth'         => $depth,
        'limit'         => $limit,
        'offset'        => $offset,
        'includeTVs'    => '1',
        'processTVs'    => '1',
        'includeContent' => '1',
        'tpl'           => $tpl,
        'debug'         => $debug,
        'sortby'        => $sortby,
        'showHidden'    => $showHidden,
        'hideContainers'=> $hideContainers,
    ));

   $output['posts'] = '<div class="post-group" style="display:none" >' . $posts . '</div>';

   if(strlen($posts) == 0){

   $output['lastpost'] = TRUE;

   }

   $output = $modx->toJSON($output);

    return $output;

Hi Sean，在集成代码的过程中，我在控制台中得到了以下信息：Object{status:“success”，msg:“message”，data:“blaaaaaaaah”，lastpost:true，posts:“}nodatalooks当时看起来像是在工作-您得到了带有~some~数据的默认成功数组，但可能runsnippet没有返回任何东西。嗯，奇怪。你有没有想过为什么runsnippet没有返回任何内容？不是真的-我在runsnippet中遇到的一个问题是它只返回字符串[没有数组、对象等]，但这看起来不是问题所在-你有渲染的块，所以它正在做一些事情。在snippet函数外部构建数组并转储它，以便准确地看到传递的内容，然后查看是否可以说服get resources返回调试信息[不要指定块并将debug设置为1]或发布修改后的代码这是传递的Javascript:
Object{snippet:“ajax分页”，limit:5，offset:0，parents:5，depth:999，sortby:“publishedon”，debug:1，tpl:“blog item”}
我得到一个“POST 200 OK”，所以数据看起来是发送的，但我得到的是返回的[object object]（未定义）。
