<script type="text/javascript">
function getFeeds(){
alert("get Feeds");
var newsfeed=new gfeedfetcher("rssfeeds", "rssfeedsclass", "_new")
newsfeed.addFeed("VANILLA", "
http://vanillajava.blogspot.com/feeds/posts/default?alt=rss";);
newsfeed.addFeed("GOOGLE NEWS", "http://news.google.com/?output=rss";);
newsfeed.addFeed("BLOGOOLA's Blog", "http://blogoola.com/blog/feed/";);
newsfeed.displayoptions("label datetime snippet");
newsfeed.setentrycontainer("p");
newsfeed.filterfeed(15, "date");
newsfeed.init();
