title: How to get results after submit form with PhantomJS?
body: <p>I'm trying to get results from a simple form using PhantomJS. I'm using jQuery but don't work. I have this HTML:</p>
  
  <pre class="lang-php prettyprint-override"><code>&lt;!doctype html&gt;
  &lt;html&gt;
  &lt;head&gt;
      &lt;title&gt;PhantomJS!&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;form method="post" id="frm"&gt;
  &lt;input type="text" name="nombre" id="nombre" /&gt;
  &lt;input type="submit" value="Publicar" id="btn-submit" /&gt;
  &lt;/form&gt;
  
  Your name is &lt;span id="nombrez"&gt;&lt;?php if (isset($_POST['nombre'])) { echo $_POST['nombre'];} ?&gt;&lt;/span&gt;
  
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>And this Javascript code:</p>
  
  <pre class="lang-js prettyprint-override"><code>var page = require('webpage').create();
  page.open('http://localhost/phantom/', function() {
    page.includeJs("https://code.jquery.com/jquery-3.1.1.slim.js", function() {
      page.evaluate(function() {
  
        $('#nombre').val('Fabian');
      document.forms[0].submit();
     });
  
      page.onLoadFinished = function(){
  
      console.log($("#nombrez").html());
      phantom.exit();
  
      };  
  
  
    });
  });
  </code></pre>
