Question

这是html代码：

<div id="jstree-beanDescCategorie" class="jstreeDiv" style="display: none;">

<div class="containerjsTree jstree jstree-2 jstree-default jstree-checkbox-selection" role="tree" aria-multiselectable="true" tabindex="0" aria-activedescendant="3" aria-busy="false">

<ul class="jstree-container-ul jstree-children jstree-wholerow-ul jstree-no-dots" role="group">

  <li id="2" class="jstree-node jstree-closed" role="treeitem" aria-selected="false" aria-level="1" aria-labelledby="2_anchor" aria-expanded="false">

  <div class="jstree-wholerow" unselectable="on" role="presentation"></div>
  <i class="jstree-icon jstree-ocl" role="presentation"></i>
  <a id="2_anchor" class="jstree-anchor" href="#" tabindex="-1"></a>

  </li>

当分支打开时，类会更改为＆＃34; jstree-node jstree-open＆＃34;

我使用Tchromium嵌入delphi 我试过了：

 var x = document.getElementsByClassName("jstree-node jstree-closed");
 x[1].click();

没有发生任何事情，虽然x不是空的

您不应该更改类，而是获取实例并在其上调用knife cookbook：

open_node
