Is it possible to trigger share menu on smartphones (via HTML/JS)?

Question

Is there an existing possibility to trigger the share functionality in local browsers on smartphones via HTML or JavaScript?

Of course there are many services which provide a share button. But when I e.g. want to share a website on facebook, I need to be logged in to facebook in the browser I am currently using.

Almost all browsers got an own share functionality build in, which triggers a system menu to choose which app you want to use to share:

This question is about: How to trigger this menu?

I know it is possible to trigger a phone call with a specified prefix in href attribute of links, like tel: or callto:. Maybe such a shortcut for this share menu is also existing? Or some javascript code? Or a totally different way how to do it?

Thanks in advance.

It is possible with a big catch. Currently only available in Chrome for Android and on Safari (desktop and mobile). http://caniuse.com/#feat=web-share

if (navigator.share) {
  navigator.share({
    title: document.title,
    text: "Hello World",
    url: window.location.href
  }).then(() => console.log('Successful share'))
  .catch(error => console.log('Error sharing:', error));
}
