I have a news feed where items in the feed are created from JSON returned from a server. When the user takes an action on an item, I want to remove it from the object via javascript.

The feed looks like this:

{"newsFeed":[{"feedId":"1",
              "title":"item1 title",
              "desc":"description of the item"},
             {"feedId":"2",
              "title":"item2 title",
              "desc":"description of the item"}]}

I'm trying to remove a JSON attribute or entry where the feedId is passed in via a variable using jQuery. I'm not sure exactly where I'm going wrong here, but when I alert the feed before and after the removal of the object, I'm getting the same response:

function removeFromFeed(feedId){
  var newsFeed=jQuery('div#newsFeed').data('newsFeed');
  alert(newsFeed.toSource());
  delete newsFeed.feedId[feedId]
  jQuery('div#newsFeed').data('newsFeed',newsFeed);
  alert(newsFeed.toSource());
}
