AngularJS - Get $scope variable from string -

so have $scope variable defined so:

$scope.data = { filter: { state: 'wa', country: 'us' } };

how access in separate service string? e.g. data.filter in context of $scope.

so have service method so:

function dosomething($scope, variablename) { // want access $scope[variablename] here?? }

i phone call controller so:

service.dosomething($scope, 'data.filter');

you want utilize $eval:

function dosomething($scope, variable) { var info = $scope.$eval(variable); // logs {state: "wa", country: "us"} console.log(data); }

however, if wanted functionality every time contents changes, preferable utilize $watch

function dosomething($scope, variable) { $scope.$watch(variable, function(data) { // logs {state: "wa", country: "us"} console.log(data); }); }
