Question

我能够正确地console.log所有值，但是表达式img ng-src =“ {{$ scope.bus}}”“未被评估。我对angularJ很陌生，任何帮助都会很棒。下面是代码

$scope.showAdvanced = function (ev, bus) {

      $scope.bus = bus;
      console.log(bus);
      console.log("scope.bus ="+$scope.bus);
      $mdDialog.show({
        controller: DialogController,
        template: '<div role="dialog" aria-label="Eat me!" layout="column" layout-align="center center">' +
          '    <md-toolbar>' +
          '      <div class="md-toolbar-tools">' +
          '        <h2>Surprise!</h2>' +
          '      </div>' +
          '    </md-toolbar>' +
          '  ' +
          '   <div ' +
          '    <div id="slideDiv" class="demo-dialog-content">' +
          '      <div layout="row" >' +
          '        <img ng-src="{{$scope.bus}}">' +
          '      </div>' +
          '    </div>' +
          '  ' +
          '    <div layout="row" class="demo-dialog-button">' +
          '      <md-button md-autofocus flex class="md-primary" ng-click="cancel()">' +
          '        Close' +
          '      </md-button>' +
          '    </div>' +
          '  </div>',
        parent: angular.element(document.body),
        targetEvent: ev,
        clickOutsideToClose: true,
        fullscreen: $scope.customFullscreen // Only for -xs, -sm breakpoints.
      })
    };

Answer 1

$ scope在这种情况下不起作用，因为它是一个孤立的。您可以尝试添加 locals 吗？谢谢。

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse,
                            withCompletionHandler completionHandler: @escaping () -> Void) {


    let notificationTitle = response.notification.request.content.title
    let info = response.notification.request.content.userInfo
    let data = info["moduledata"] as? String ?? ""
    switch notificationTitle {
    case "Notice Added":

        let vc = NoticeDetailViewController()
        vc.noticeID = data
        let navVC = UINavigationController(rootViewController: vc)
        window?.rootViewController = navVC

    case "Practicework Added":

        let vc = HomeworkDetailViewController()
        vc.id = data
        let navVc = UINavigationController(rootViewController: vc)
        window?.rootViewController = navVc

    default:
        print("")
    }
    completionHandler()
}

或

按照第一种方法。

locals: {bus: $scope.bus}

$scope.showAdvanced = function (ev, bus) {

      $scope.bus = bus;
      console.log(bus);
      console.log("scope.bus ="+$scope.bus);
      $mdDialog.show({
        controller: DialogController,
        controllerAs: 'DialogCtrl',
        template: '<div role="dialog" aria-label="Eat me!" layout="column" layout-align="center center">' +
          '    <md-toolbar>' +
          '      <div class="md-toolbar-tools">' +
          '        <h2>Surprise!</h2>' +
          '      </div>' +
          '    </md-toolbar>' +
          '  ' +
          '   <div ' +
          '    <div id="slideDiv" class="demo-dialog-content">' +
          '      <div layout="row" >' +
          '        <img ng-src="{{DialogCtrl.bus}}">' +
          '      </div>' +
          '    </div>' +
          '  ' +
          '    <div layout="row" class="demo-dialog-button">' +
          '      <md-button md-autofocus flex class="md-primary" ng-click="cancel()">' +
          '        Close' +
          '      </md-button>' +
          '    </div>' +
          '  </div>',
        parent: angular.element(document.body),
        targetEvent: ev,
        clickOutsideToClose: true,
        fullscreen: $scope.customFullscreen // Only for -xs, -sm breakpoints.
      })
    };

不在模板html中评估AngularJS表达式$ scope
