remove json attribute where attribute is a variable
- by pedalpete
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());
}
