我的回调下面无法更新/访问我的$scope变量(或者,由于某些原因,更改没有显示),我该如何实现？
正在调用回调函数,但我认为这里的 javascript范围显然不对.

- function ReportsCtrl($scope) {
- var self = this;
- $scope.analyticsIsReady = false;
- $scope.analyticsInitStatus = '';
- //$scope.originCompositionChart = new Chart__('originCompositionChart',reportsClient.getOriginCompositionData,true,false);
- $scope.originCompositionChart = new Chart__('originCompositionChart',null,false);
- $scope.charts = new Array($scope.originCompositionChart);
- $scope.showIncludedCharts = function () {
- };
- //todo not working
- this.updateAnalyticsInitStatus = function (status) {
- console.log('boom; ' + status);
- $scope.analyticsInitStatus = status;
- };
- //todo not working
- this.handleAnalyticsInitSuccess = function (status) {
- $scope.analyticsInitStatus = 'Initialisation complete';
- $scope.analyticsIsReady = true;
- };
- window.analyticsInitialiserClient = new AnalyticsInitialiserClient__(this.updateAnalyticsInitStatus,this.handleAnalyticsInitSuccess);
- }
正如@charletfi建议的那样,你需要在$apply中包装来自Angular外部的回调来指示Angular运行一个摘要周期来确定更改.
- // Should now work
- this.updateAnalyticsInitStatus = function (status) {
- $scope.$apply(function () {
- console.log('boom; ' + status);
- $scope.analyticsInitStatus = status;
- });
- };
