| | | <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>Return </b><span>ES6 Promise</span></h4> |
| | | <p>Promise Object of ES6</p> |

| | | <h4>1. reload root nodes</h4> |
| | | <pre xmlns=""><code>var treeObj = $.fn.zTree.getZTreeObj("tree"); |

| | | </code></pre> |
| | | <h4>2. reload the first selected node's child nodes.</h4> |
| | | <pre xmlns=""><code>var treeObj = $.fn.zTree.getZTreeObj("tree"); |
| | | var nodes = treeObj.getSelectedNodes(); |
| | | if (nodes.length>0) { |
| | | treeObj.reAsyncChildNodes(nodes[0], "refresh"); |
