title: Form 'action' for form without GET or POST
body: <p>I have a 'form' that generates a url for a user via javascript. This is the HTML I have -- </p>
  
  <pre><code>&lt;form class="hidden profile-private-link-form"&gt;
      &lt;span class="link"&gt;
          &lt;input type="text" name="" value="&lt;value&gt;" /&gt;
      &lt;/span&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>However, when I try and validate the HTML it says 'action need to be specified'. Is it fine to omit the action here, or what should I put instead?</p>
