从外部调用控制器功能

Question

I need to access (call and/or modify) the scope of a controller from outside of it.
Following this answer I managed to access the scope, but the data binding doesn't kick in...

Take this as example ( JSFiddle ).

angular.module("App", []).controller("Test", function($scope)
{
    $scope.list = ["added on initialization"];

    $scope.add = function(item)
    {
        $scope.list.push(item);
    };
});

var addFromOutside = function()
{
    angular
        .element(document.getElementById("TestController"))
        .scope()
        .add('added from outside');
};

<div ng-app="App" ng-controller="Test" id="TestController">
    <ul>
        <li ng-repeat="item in list track by $index">
            {{item}}
        </li>
    </ul>

    <button ng-click="add('added from inside')">Add from inside</button>
</div>

<button onclick="addFromOutside()">Add from outside</button>

If you click in the " Add from inside " button it works like expected.
But if you click in the " Add from outside " button nothing happens until you click in the " Add from inside " button...

Is there anyway to do this and the have data binding working?

Answer 1

you forgot to add

scope.$apply()

http://jsfiddle.net/o2b0bdbr/ you are outside of angulars digest cycle so you need to let him know that something happen to on of his scopes
