  <blockquote>
    <p>TypeError: $(...).jstree.get_node is not a function</p>
  </blockquote>
  
  <p>this is html code:</p>
  
  <pre><code>&lt;div style="height: 75%; margin: 0; width: 100%;"&gt;
                      &lt;div id="dashboardTree" style="border: 0; height: 99%; margin: 0; margin-top: 2px; overflow: auto; width: 99%;"&gt;
                      &lt;/div&gt;
                  &lt;/div&gt;
  </code></pre>
  
  <p>this is the javascript:</p>
  
  <pre><code>$(document).ready(function () {
  initDashboardArchiveTree();//Initial tree
  var node = $('#dashboardTree').jstree(true).get_node('1')//get that error
  });
  </code></pre>
