Question

我不能在我的控制器中使用$ scope.data，它是未定义的，你能帮忙吗？

由于

contact.html

- (void)locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region {
    NSLog(@"Yes! Welcome to %@",region.identifier);
    UILocalNotification* notify = [UILocalNotification new];
    notify.alertBody = [NSString stringWithFormat:@"Welcome to %@",region.identifier];
    notify.soundName = UILocalNotificationDefaultSoundName;
    if (notify.applicationIconBadgeNumber == 0) {
        notify.applicationIconBadgeNumber = 1;
    }
    [[UIApplication sharedApplication] presentLocalNotificationNow:notify];
}

controllers.js

<textarea cols="40" rows="6" name="message" id="message" class="panelInputs" placeholder="Message" ng-model="data.message" ng-change="displayscope()"></textarea>

app.js

angular.module('BoardLine.controllers', ['BoardLine.services'])
.controller('ContactCtrl', function($scope, $stateParams, sessionService, isPhoneGap, isIOS) {
  console.log($scope.data);
  $scope.displayscope = function() {
    console.log("displayscope : ");
    console.log($scope.data);
  }
})

Answer 1

您需要首先在控制器中定义属性data，如$scope.data = {}。因为ng-model与data.message绑定，而data为undefined。因此无法分配message。

Answer 2

在你的控制器中你应该声明$ scope.date对象

    angular.module('BoardLine.controllers', ['BoardLine.services'])
.controller('ContactCtrl', function($scope, $stateParams, sessionService, isPhoneGap, isIOS) {
//add this
$scope.data = {};

  console.log($scope.data);
  $scope.displayscope = function() {
    console.log("displayscope : ");
    console.log($scope.data);
  }
})

$ scope.data在控制器中未定义
