title: JavaScript suppress date format warning
body: <p>Whenever I try to reset a date input using JavaScript, like so:</p>
  
  <pre><code>//input_id is an id of a date input
  document.getElementById(input_id).value = "0000-00-00";
  </code></pre>
  
  <p>I get a warning in the console:</p>
  
  <pre><code>The specified value "0000-00-00" does not conform to the required format, "yyyy-MM-dd".
  </code></pre>
  
  <p>Does anyone know a way to suppress this warning so it won't show? The JS keeps on running smoothly but I want to get rid of these warnings.</p>
  
  <p>If you have another way of resetting a date input (without raising a warning) I will be happy to hear.</p>
  
  <p>Thanks in advance.</p>
