Javascript 如何更新角度范围

我想在控制器中对从服务器获取的数据进行一些更改。我举了一个例子来解释我的问题。递归方法update似乎不会更新$scope.gdevPiechartArchiveVolume的值。有人能告诉我为什么吗？有没有办法触发更新？谢谢大家!

angular.module('socketTestApp')
    .controller('MainCtrl', function($scope, Socket) {

        Socket.on('gdevAreachart_archiveVolume_update', function(data_) {
            selectArchiveData(data_);
        });
        function selectArchiveData(data) {

            var i = 0;
            var selectedData;


            $scope.update = function() {
                _.delay($scope.update, 2000);

                if ($scope.pause)
                    return

                i++
                $scope.gdevPiechartArchiveVolume = i;   //<--- this seems not to work but only if i set $scope.pause true
                console.log('Updates in $scope.update: ' + $scope.gdevPiechartArchiveVolume);
            }


            $scope.update();

        }

控制台输出指令：。。。应像$scope中的更新一样每次打印。更新：：

您是否尝试过使用$scope.$apply？

每当您想从angular不关心的函数更新angular$scope时，您都需要这样做，在您的示例Socket中。当$scope.pause=true时，如果$scope.pause return将返回且$scope.gdevPiechartArchiveVolume=i；不会执行。很高兴我能帮忙，别忘了将答案标记为正确答案：

angular.module('socketTestApp')
    .directive('gdevAreachart', function() {
        var linker = function(scope, element, attr) {

            scope.$watch('data', function(newVals, oldVals) {
                console.log("Direktive: " + newVals);
                return //make some other thinks
            }, true);

Direktive: undefined gdevAreachart.js:14
Updates in $scope.update: 1 main.js:127

function selectArchiveData(data) {

            var i = 0;
            var selectedData;


            $scope.update = function() {


                if ($scope.pause)
                    return

                i++
                $scope.gdevPiechartArchiveVolume = i;
                console.log('Updates in $scope.update: ' + $scope.gdevPiechartArchiveVolume);
                setTimeout(function() {
                   $scope.$apply($scope.update());
                }, 2000);
            }
            $scope.update();

        }
