ShareThis is a web service that provides an easy way of sharing data. The jQuery ShareThis plugin uses jQuery to stick the ShareThis widget on any element. Using this also means that the ShareThis API will be loaded after the whole page has been rendered, making the page seem to load faster.
$('a.sharethis').sharethis();
Calling the jQuery sharethis() function will create a ShareThis widget on the given object. It will use the href and title tags to create the widget.
Note that you can pass the ShareThis API URL from ShareThis's Get the Button for the sharethis() call, and the given settings will be set.
$('a.sharethis').sharethis('http://w.sharethis.com/button/sharethis.js#headerTitle=ShareThis%20Widget');
