        <h3>Function Parameter Descriptions</h3>
        <div class="desc">
            <h4><b>parentNode</b><span>JSON</span></h4>
            <p>The parent node which will asynchronous loading child nodes.</p>
            <p class="highlight_red">1. If parentNode = null, it is same as reload root nodes.</p>
            <p class="highlight_red">2. If parentNode.isParent = false, don't load nodes.</p>
            <p class="highlight_red">3. Please ensure that this data object is an internal node data object in
                zTree.</p>
            <h4 class="topLine"><b>reloadType</b><span>String</span></h4>
            <p>reloadType = "refresh" means: reload child nodes.</p>
            <p>reloadType != "refresh" means: append to load child nodes.</p>
            <h4 class="topLine"><b>isSilent</b><span>Boolean</span></h4>
            <p>Set whether to automatically expand the parent node, after load nodes.</p>
            <p>isSilent = true means: don't auto expand the parent node. Otherwise auto expand.</p>
            <h4 class="topLine"><b>callback</b><span>function</span></h4>
            <p>zTree will trigger this callback() function after reAsyncChildNodes()</p>
            <h4 class="topLine"><b>Return </b><span>none</span></h4>
