title: How to Perform a Javascript function using Primefaces wizard onnext attribute?
body: <p>I am using PrimeFaces 5.3 and eventually want to use the onnext attribute of the wizard to hide the Next button using hideNextNav(). However, I am currently just trying to test this functionality by calling the next() method instead. Since I am new to primefaces and jsf in general, I have attempted using various syntax, but all my attempts have rendered the Next button non-functional. When I try alert() instead, it works correctly, showing a message box and proceeding to the next tab. </p>
  
  <p>My error:</p>

  <p>My xhtml code:</p>
  
  <pre><code>&lt;script&gt;
      function nextf(){
          PF('wizard').next();
      }
  &lt;/script&gt;
  ...
  &lt;p:wizard widgetVar="wizard" flowListener="#{editController.onFlowProcess}" onnext="nextf();"&gt;
  </code></pre>
  
  <p>Your help would be greatly appreciated.</p>
