<p>This example contains a form with two submit buttons. The first submit button submits the form data with default character encoding, and the second submits the form data without character encoding:</p>

<form action="/action_page_binary.asp" method="post">
  Name: <input type="text" name="fname" value="St�le Refsnes"><br>
  <button type="submit">Submit with character encoding</button>
  <button id="myBtn" type="submit" formenctype="text/plain">Submit without character encoding</button>
</form>

<p>If you click on the submit buttons above, notice that the formenctype attribute overrides the HTML form's enctype attribute (default is "application/x-www-form-urlencoded").</p>

<p>Click the "Try it" button to return the value of the formenctype attribute of the second submit button above.</p>
