AngularDart ng-change

Question

我有html:

<select ng-model="main.selectedReport" ng-change="main.selectReport()">
                            <option value="">Not selected</option>
                            <option ng-repeat="rep in main.reports" value="{{rep.value1}}">{{rep.value2}}</option>
                        </select>

我的控制器是:

@NgController(selector: '[main-controller]', publishAs: 'main')
class MainController extends FCViewAbstractController {

  Map reports;
  Long selectedReport;

....

  selectReport() {
    print(selectedReport);
  }
}

我的问题是为什么我在selectReport()中获得先前选择的值？例如:在第一次选择时,我得到了空值.

但是angularjs中的版本可以正常工作http://plnkr.co/edit/ILBBWfkRp9tegQZaGZ9u?p=preview

Answer 1

似乎是在模型更新之前调用的已知错误 ng-change#399

解决方法:

  selectReport() {
    new Future(() => print(selectedReport));
  }
