gAjax RSS Feeds Displayer v2.0

1) gAjax RSS Feeds Displayer v2.0

2) http://www.dynamicdrive.com/dynamici...sdisplayer.htm

3) I'm trying to create a feature that would allow a user to load multiple rss feeds using a set of check boxes. I can get it so that when a checkbox is clicked it loads up the selected rss feed, but I can't figure out how to clear it when it's unchcked. Any thoughts or help on this?

function validate1(){
  var yahoo = document.getElementById('yahoo');
  if (yahoo.checked){
    example3.addFeed("Yahoo", "http://dir.yahoo.com/rss/dir/getrss.php?arts");
	example3.init()
  } else {
  //clear rss feed

  }
}         

function validate2(){
  var msnbc = document.getElementById('msnbc');
  if (msnbc.checked){
    example3.addFeed("MSNBC", "http://feeds.nbcnews.com/feeds/topstories");
	example3.init();
  } else {
  //clear rss feed

  }

You can use this function (using a text only editor like NotePad, add it to the end of the gfeedfetcher.js file):

function removefeed(feed, removelabel){
	var labels = feed.feedlabels, i = -1, keptfeeds = {};
	while (++i < labels.length){
		if(labels[i] !== removelabel){
			keptfeeds[labels[i]] = feed.feedurls[i];
		}
	}
	feed.feedcontainer.innerHTML = '';
	feed.feeds = {};
	feed.feedlabels = [];
	feed.feedurls = [];
	for(var f in keptfeeds){
		feed.addFeed(f, keptfeeds[f]);
	}
	feed.feedlabels.length && feed.init();
}

For example:

function validate1(){
  var yahoo = document.getElementById('yahoo');
  if (yahoo.checked){
    example3.addFeed("Yahoo", "http://dir.yahoo.com/rss/dir/getrss.php?arts");
	example3.init()
  } else {
  removefeed(example3, 'Yahoo'); //clear rss feed

  }
}

Just be aware that, if example3 has no other feeds, it will be empty after removing it's only feed.
