  <p>I like it, and it's totally ok with me to have it work only in chrome.</p>
  
  <p>The question is <strong>how can I invoke date picker for this input field in javascript?</strong></p>
  
  <p>Normally there is only input field until user focus it and click little black triangle to open small calendar. I want to open it from javascript.</p>
  
  <p>I would like to avoid 3rd party date picker implementations if possible.</p>
  
  <p>I've tried <code>element.focus()</code>, <code>element.click()</code>, etc.</p>
