I have an application that has set of data that has a recursive relationship (a tree view, using recursion.) I\'ve tried several ways to implement this via Angular, none of
Try this for a nice clean example
http://codrspace.com/build80/create-recursive-tree-structure-using-template-in-angularjs/
rather than nest your controllers, nest the data and just have the one controller.
the view is handled by a template that references itself recursively.
as chadermani has linked to, there are some answers out there.
here is a fiddle with a great example (not my code)
http://jsfiddle.net/brendanowen/uXbn6/8/
and the code from the fiddle
<script type="text/ng-template" id="tree_item_renderer.html">
{{data.name}}
<button ng-click="add(data)">Add node</button>
<button ng-click="delete(data)" ng-show="data.nodes.length > 0">Delete nodes</button>
<ul>
<li ng-repeat="data in data.nodes" ng-include="'tree_item_renderer.html'"></li>
</ul>
</script>
<ul ng-app="Application" ng-controller="TreeController">
<li ng-repeat="data in tree" ng-include="'tree_item_renderer.html'"></li>
</ul>
angular.module("myApp", []).
controller("TreeController", ['$scope', function($scope) {
$scope.delete = function(data) {
data.nodes = [];
};
$scope.add = function(data) {
var post = data.nodes.length + 1;
var newName = data.name + '-' + post;
data.nodes.push({name: newName,nodes: []});
};
$scope.tree = [{name: "Node", nodes: []}];
}]);
If you are familiarized with batarang tool, it has a treeview of scopes. You can see the source here:
https://github.com/angular/angularjs-batarang/blob/master/js/directives/scopeTree.js
The idea is simple. Using $compile to recursively render that directive for every children it finds until there is no more children to render.
I saw that same idea for other alternatives, take a look here:
Is it possible to make a Tree View with Angular?
