TypeError：无法设置属性＆＃39; notification＆＃39;未定义的

Question

示例：

setting.html
这个html用于动态显示md-switch切换按钮

  <md-dialog-content ng-repeat="notifications in languagelabels.notification">
    <div layout="row">
        <div flex=70>{{ ::notifications }}</div>
        <div flex=30>
            <md-switch ng-model="data.notification.subscription"  aria-label="{{::notifications}}"></md-switch>
        </div>
    </div>
  </md-dialog-content>

controller.js 这是从md-switch

获取值

app.controller('SettingController', function($scope, $rootScope, $http, $mdDialog, data, $timeout) {

$scope.languagelabels = data;
//console.log(data.notification);
//$scope.notifications=['New Booking','Cancellation','Modification','Last Minute Booking'];
var old = {
    subscription: (window.localStorage.getItem('subscrid') == 1) ? true : false
};
$scope.data={};
$scope.data.notification = {
    subscription: (window.localStorage.getItem('subscrid') == 1) ? true : false
};
$scope.cancel = function() {
    $mdDialog.hide(0);
} });

Answer 1

您没有使用notification

初始化data对象

你应该初始化它

$scope.data={notification:{}}; 

或者尝试以下方式

$scope.data={notification:{subscription:(window.localStorage.getItem
('subscrid') == 1) ? true : false
}};
