What is the appropriate way to assign a scope property in an angular controller when it becomes accessible?

Question

What is the appropriate way to assign a scope property in an angular controller when it becomes accessible?

In my code, there exists a global JavaScript object known as instance_

This object includes a property named current_

Later on, another property called dataset_ is assigned to current_

Therefore, we can access this dataset_ property by using instance_.current_.dataset_

I often utilize the dataset_ property within a div element to display the current dataset. However, when the controller is initialized by Angular, current_ is null. This presents an issue as I am unable to use the dataset_ property of current_ by setting

$scope = instance_.current_.dataset_

since current_ is currently null

What steps should I take in order to resolve this dilemma?

As an alternative solution attempt, are there ways to delay the initialization of this particular controller until current_view_ no longer remains null?

Answer №1

One possible solution is to create a factory in your application. Here's an example:

myApp = angular.module('myApp', []);
myApp.factory('myGlobalDataSet', function(){
    return instance_.current_.dataset_;
});

Next, inject the factory's value into your controller:

function myController($scope, myGlobalDataSet) {
  $scope.myGlobalDataSet = myGlobalDataSet;
}

Now you should be able to access the myGlobalDataSet variable within your views. By using ng-model, you can bind the global value to the view details.
