How to manipulate async scope in angularjs

Question

I have this defined in controller $scope.files = {};

Then I have a ajax call to get data and pass to $scope.files;

In the same controller. I have a ng-click function which I want to manipulate $scope.files How to do that because it is async. I tried and the $scope.files always return blank {}

$scope.click = function() {
 //Do something to $scope.files;
}

You're not really showing us enough code to help you. Do you have a fiddle or a plunker you can show? — Ben Lesh

Are you calling $scope.click() in the callback of your get request? — Zack Argyle

@ZackArgyle I call it outside and inside the cb both not work. — vzhen

My fault. this is not related to async. I can actually get the data.

My problem is the return data is object and I tried to use .length to get the length of object so it always return 0 and {}. And I found .length for array.

and Object.keys(a) for object sizes

Looks like you need to use promise/deferred implementation. Promises allow you to execute code and once the promise is returned then continue.
