not able to access $scope object outside a http response callback function in angularjs

Question

I have this controller for saving some details for an individual. I have a separate repository EntityRepository where a function to get the user gender from database is defi

Answer 1

The reason why you can't access the value of $scope.userGender outside the AJAX success callback is simple: AJAX is asynchronous, meaning that a value to this variable will be assigned only after this AJAX call succeeds. You should adapt your code so that it doesn't depend on the value of $scope.userGender before this AJAX call has succeeded. If this value is data bound to some control in the markup, then this is not a problem, the value will appear with a little delay when the value is retrieved from the server.

Answer 2

Can you try this.

  $scope.GetUserGender = function(){
 EntityRepository.getUserGender().then(function(response){
    $scope.userGender = response.data.gender;
    console.log("inside : ", $scope.userGender);
  }).catch(function(errorResponse) {
    $scope.error = errorResponse.data
  });     
}
  $scope.GetUserGender();   //

 console.log("outside : ", $scope.userGender);

Hope this will work :)

Answer 3

You are not able to access the value outside due to asynchronous property of requests. What that simply means is that this statement: console.log("outside : ", $scope.userGender);, is getting executed before the .then(function(){ ... }).

Fixes:

1. Wrap your outside code inside of $timeout

.controller('individualDetailsCtrl', function($scope, $rootScope, $location, EntityRepository, $timeout) {

and

$timeout(function() {console.log("outside : ", $scope.userGender)});

2. Use $scope.userGender's value only inside the .then(function() { }).
