/**
* This file includes objects for binding and accessing the feed menu
*/
/**
* HOWTO
*
We create a new instance of the menu. Then we need to bind it on an ul which contains
all the items:
var updateIntervalMiliseconds = 2000;
var items = new News.Items('#feed_items');
var menu = new News.Menu(updateIntervalMiliseconds, items);
menu.bindOn('#feeds ul');
Updating nodes (you dont have to set all values in data):
var nodeType = News.MenuNodeType.Feed;
var nodeId = 2;
var nodeData = {
unreadCount: 4,
title: 'The verge'
}
menu.updateNode(nodeType, nodeId, nodeData);
Deleting nodes:
var id = 2;
var type = News.MenuNodeType.Feed;
var removedObject = menu.removeNode(type, id);
Creating nodes:
var parentId = 0;
var nodeType = News.MenuNodeType.Feed;
var nodeId = 6;
var nodeData = {
title: 'hi',
icon: 'some/icon.png',
unreadCount: 3
};
menu.addNode(parentId, nodeType, nodeId, nodeData);
If you want to show all feeds, also feeds which contain only read items, use
menu.setShowAll(true);
If you want to hide feeds and folders with only read items, use
menu.setShowAll(false);
The default value is false. If you want to toggle this behaviour, theres a shortcut
menu.toggleShowAll();
To hide all articles with read feeds, the setShowAll has to be set to false. The
hiding is only triggered after a new feed/folder was being loaded. If you wish to
trigger this manually, use:
menu.triggerHideRead();
If you want to load a feed or folder directly, use
var id = 2;
var type = News.MenuNodeType.Folder;
menu.load(type, id);
