How to invoke date picker from date input in javascript? [duplicate]

Question

Chrome has native date picker for <input type="date">:

I like it, and it's totally ok with me to have it work only in chrome.

The question is how can I invoke date picker for this input field in javascript?

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.

I would like to avoid 3rd party date picker implementations if possible.

I've tried element.focus(), element.click(), etc.

Answer 1

I figured it out.

The trick is to send F4 keyboard event.
