Implement social media share buttons?

You need to implement the ability to publish on social networks through the site. I tried, for example, in vk the following:

        url  = 'http://vk.com/share.php?';
        url += 'url='          + encodeURIComponent('mysite.com');
        url += '&title='       + encodeURIComponent('title');
        url += '&description=' + encodeURIComponent('description');
        url += '&noparse=true';
        window.open(url,'','toolbar=0,status=0,width=626,height=436');

But I was faced with the fact that the description comment section of the post (in the popup) is not filled in. Plus, the {[5] button doesn't work in the popup itself]}tell your friends on the page, but the moment works if you send the record by private message.

I tried the option from the docks vk, problems identical:

<script type="text/javascript" src="https://vk.com/js/api/share.js?93" charset="windows-1251"></script>
<script type="text/javascript">
...
document.write(VK.Share.button({
  url: 'http://mysite.com',
  title: 'Заголовок страницы',
  description: 'Это мой собственный сайт, я его очень долго делал',
  image: 'http://mysite.com/mypic.jpg',
  noparse: true
}));

Is there any ready-made basic template for sharing in social networks (without downloading packages in npm)?

I should have vk, fb, twitter.
