Una utilidad muy buena para los blogs es incluir un widget para que los usuarios puedan ver entradas aleatorias. Esto se consigue con Javascript y un enlace simple, una imagen o, como en este caso un boton. Con un poco de codigo de CSS3, he diseñado este boton naranja tan chulo con efecto 'presionado', que haciendo click sobre el, te muestra un post al azar automaticamente. Para ponerlo en tu blog de Blogger, tan solo tienes que copiar el codigo de abajo y añadirlo en un gadget HTML, asi de sencillo

<div id='postaleatorio'></div>
<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 = 'Ver una entrada al azar'; document.getElementById('postaleatorio').appendChild(a); } </script> <script src='/feeds/posts/summary?max-results=0&alt=json-in-script&callback=feelingLucky'></script>
