我正在使用ionic进行移动应用,我需要在设备旋转时处理视图,因此我使用此代码检测屏幕并更新视图:

$scope.products = [];
$rootScope.dato = [];

ProductsService.getProductsFromCategory($scope.category_id).then(function(data){
  $rootScope.dato = data.data.products;
  load_data($rootScope.dato);
  console.log("############# xxxxdxxxdxxxxdxxxxd ##############" +JSON.stringify($rootScope.dato));
  $ionicLoading.hide();
});

$scope.calculateDimensions = function(gesture) {
  console.log("############# Calculate produit ##############" +JSON.stringify($rootScope.dato));
  $scope.dev_width = $window.innerWidth;
  $scope.dev_height = $window.innerHeight;
  $scope.devider = parseInt($scope.dev_width / 150);
}

angular.element($window).bind('resize', function(){
  $scope.$apply(function() {
    console.log("############# test Calculate produit ##############" +JSON.stringify($rootScope.dato));
    load_data($rootScope.dato);
  })       
});

function load_data(products) {
  $scope.calculateDimensions(); 
  console.log("############# befir called ##############" +JSON.stringify(products));

  $scope.products = [];
  while (products.length) {
      $scope.products.push(products.splice(0, $scope.devider))
  }
  console.log("############# after called ##############" +JSON.stringify($scope.products));
  console.log("############# befir called ##############" +JSON.stringify($rootScope.dato));
}

我的$ scope.data第一次包含一个json数组但是当我旋转一个设备时,我的$ scope.data显示了一个空数组[]。

感谢。
