<center><div id="mbb-random"></div></center>
<script type="text/javascript">
function showLucky(root){ var feed = root.feed; var entries = feed.entry || []; var entry = feed.entry[0]; for (var j = 0; j < entry.link.length; ++j){if (entry.link[j].rel == 'alternate'){window.location = entry.link[j].href;}}} function fetchLuck(luck){ script = document.createElement('script'); script.src = '/feeds/posts/summary?start-index='+luck+'&max-results=1&alt=json-in-script&callback=showLucky'; script.type = 'text/javascript'; document.getElementsByTagName('head')[0].appendChild(script); } function feelingLucky(root){ var feed = root.feed; var total = parseInt(feed.openSearch$totalResults.$t,10); var luckyNumber = Math.floor(Math.random()*total);luckyNumber++; a = document.createElement('a'); a.href = '#random'; a.rel = luckyNumber; a.onclick = function(){fetchLuck(this.rel);}; a.innerHTML = 'Random Post'; document.getElementById('mbb-random').appendChild(a); } </script><script src="/feeds/posts/summary?max-results=0&alt=json-in-script&callback=feelingLucky">
</script>

The next thing to do after adding the above code in a HTML/Javascript widget is to save the widget and template too. Open your blog on a new window and see it displaying LIVE! Now, you have a fanciful RANDOM button on your blog which you and your visitors can fully make use of.
