Bookmarklet Code

bookmarklet.html

    <p>Grab our <a id="bookmarklet" href="">Pin It</a> bookmarklet and put it on your bookmarks bar.</p>
    <!-- The script below sets the href above with the correct host, so it'll work both on localhost:8080 
          and on the real host. -->
<script>
link = document.getElementById('bookmarklet');
link.href = "javascript:(function(){ _my_script=document.createElement('SCRIPT');_my_script.type='text/javascript';_my_script.src='http://" 
    + location.host + "/js/bookmarklet.js?x='+(Math.random());document.getElementsByTagName('head')[0].appendChild(_my_script);})();"
