我如何在控制器中使用angular.forEach循环遍历返回的Resource对象数据

Question

I came across a similar scenario , but my attempts failed because undefined was always returned and kept on getting error after error in the console.

The data is retrieved from the openweathermap API using the angular $resource factory. I understand that i can target and get some of the data i need in the view using ng-repeat but what I also want to break down this data in the controller and access some of the keys and values. When I console.log($scope.weatherResult) variable that holds the data retrieved from the api I get a Resource object in the console.

How can I go about looping through this object to retrieve the data I need. Its basically objects within objects within arrays. In the view ng-repeat does wonders to get this data but in the controller I don't know how to retrieve it. For example if I console.log($scope.weatherResult.city) or console.log($scope.weatherResult.list) the result in the console is always undefined.

Now the data I want to retrieve is within the list array - two days worth of data, but the first object list[0].temp has temperature figures, I want to calculate the sum of those figures and divide it and get the average so I can store it in another variable in the controller and output it in the view.

I'm not sure if im taking a long route here, but i've been in similar situations before but managed to get away with it using the ng-repeat in the view. I need to learn how to do this.

Is it possible to loop through the resource object using angular.forEach() function and get the data in the temp object? I have attached an image for reference. I am still learning and gaining experience with JavaScript and angular in particular.

Answer 1

$scope.temp = []
angular.forEach(list[0].temp, function(value,key){
  $scope.temp.push(value);
})

See if this helps you.
