I added a handy Google Slide Show widget to my site, which pulls images from an RSS feed from my photo site. Radical like Zinka, but there was no photo randomization. With a little 1337 h4x0ring I was able to do it. You, too, can get the chicks. The magic happens by adding feedProcessedCallback
to the options hash. After the feed is loaded, we run a shuffle function on the feed entries. And that’s about it. Random images. Here’s my code:
<script src="http://www.google.com/jsapi" type="text/javascript"></script>
<script src="http://www.google.com/uds/solutions/slideshow/gfslideshow.js"
type="text/javascript"></script>
<script type="text/javascript">
// This does the shuffle magic
function shuffle(a) {
var i = a.length;
if ( i == 0 ) return false;
while ( --i ) {
var j = Math.floor( Math.random() * ( i + 1 ) );
var tempi = a[i];
var tempj = a[j];
a[i] = tempj;
a[j] = tempi;
}
}
google.load("feeds", "1");
function OnLoad() {
var feed1 = "YOUR_FEED_URL";
var options = {
displayTime:2000,
transistionTime:600,
linkTarget : google.feeds.LINK_TARGET_BLANK,
//When the feed gets processed, shuffle the entries
feedProcessedCallback: function() {
var e = ss.entries; shuffle(e); ss.entries = e;
}
};
var ss = new GFslideShow(feed1, "slideshow", options);
}
google.setOnLoadCallback(OnLoad);
