Twitter Social Share

twitter-share.js

// We bind a new event to our link
$('a.tweet').click(function(e){

  //We tell our browser not to follow that link
  e.preventDefault();

  // 1. We get the URL of the link 
  //or 2. URL of the page
  // 1. var loc = $(this).attr('href');
  var loc = $(location).attr('href'); // 2
  

  //We get the title of the link
  var title  = encodeURIComponent($(this).attr('title'));

  //We trigger a new window with the Twitter dialog, in the middle of the page
  window.open('http://twitter.com/share?url=' + loc + '&text=' + title + '&', 'twitterwindow', 'height=450, width=550, top='+($(window).height()/2 - 225) +', left='+$(window).width()/2 +', toolbar=0, location=0, menubar=0, directories=0, scrollbars=0');

});

Awesome, helped a lot.
