I read Tweet Button document at: https://dev.twitter.com/docs/tweet-button,
There are two ways for sharing my website to Twitter page using js:
#1: <a href="https://twitter.com/SHARE" ..... use data-attribute: eg: data-url ="MY URL"
#2: <a href="https://twitter.com/intent/TWEET? ... use params: eg: &url=my_url
</html>
<p>And what should I use way above?, currenty, Twitter counter not working on my site.</p>
<p>Thanks,<br>
