title: Clear Form after submit to iframe
body: <p>I have form which need to be submited to another domain, like this:</p>
  
  <pre><code>&lt;form id="myform" action="https://example.com" target="myiframe" method="POST"&gt;
  
     &lt;input type="text" name="email" value=""&gt;
     &lt;input type="text" name="name" value=""&gt;
     &lt;input type="text" name="phone" value=""&gt;
     &lt;input type="submit" name="submit" value="Submit"&gt;
  
  &lt;/form&gt;
  </code></pre>
  
  <p>And iframe:</p>
  
  <pre><code>&lt;iframe style="display:none;" name="myiframe" src=""&gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>This work fine, but after submit form it stays filled.
  So, how to clear (reset) form after submit?</p>
