static data consuming tree

staticDataTree.js

			var findChildData = function findChildData (targetParent, rootData) {
				if (_.isEmpty(targetParent)) {
					return rootData;
				}

				if (rootData === undefined) {
					return false;
				}

				for (var i = 0; i < rootData.length; i++) {
					var potentialMatch = rootData[i];

					if (potentialMatch.attr && targetParent.attr && potentialMatch.attr.id === targetParent.attr.id) {
						return potentialMatch.children;
					} else if (potentialMatch.children) {
						var foundChild = findChildData(targetParent, potentialMatch.children);
						if (foundChild) {
							return foundChild;
						}
					}
				}

				return false;
			};

			var staticDataSourceConsumer = function staticDataSourceConsumer (openedParentData, callback) {
				var childData = findChildData(openedParentData, staticData);

				callback({
					data: childData
				});
			};

			$('#myTree').tree({
				dataSource: staticDataSourceConsumer
			});

This tree datasource will consume static JSON for use in a tree, such as this:

			var staticData = [
				{
					name: 'Empty Folder',
					type: 'folder',
					attr: {
						id: 'emptyFolder'
					},
					children: []
				},
				{
					name: 'Full Folder',
					type: 'folder',
					attr: {
						id: 'fullFolder'
					},
					children: [
						{
							name: 'Full Folder 2',
							type: 'folder',
							attr: {
								id: 'emptyFolder2'
							},
							children: [
								{
									name: 'Folder Sibling 3',
									type: 'item',
									attr: {
										id: 'sibling3',
										'data-icon': 'glyphicon glyphicon-file'
									}
								},
								{
									name: 'Folder Sibling 4',
									type: 'item',
									attr: {
										id: 'sibling4',
										'data-icon': 'glyphicon glyphicon-file'
									}
								}
							]
						},
						{
							name: 'Folder Sibling 2',
							type: 'item',
							attr: {
								id: 'sibling2',
								'data-icon': 'glyphicon glyphicon-file'
							}
						}
					]
				},
				{
					name: 'Folder Sibling',
					type: 'item',
					attr: {
						id: 'sibling1',
						'data-icon': 'glyphicon glyphicon-file'
					}
				}
			];

So much indentations! 😲
