Question

The following anchor tag

 <a href="http://twitter.com/share" class="twitter-share-button external" data-text="check out ___ on MySite!" data-count="none" data-via="MySite">tweet</a>

I am wondering if special .js file needed? I mean, how does the browser know date-text, data-count fields? those are not standard, browser probably won’t know that they mean.

But I seearch the whole file and couldn’t find any reference to any .js file that relate to the twitter sharing.

Check out the Tweet Button Docs. You need to add the following line somewhere in your page for that special anchor to function:

<script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="https://platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");</script>
