What is the best way to transfer $scope to a service in angular.js?

I have two services listed below. When navigating to a specific URL, I need to resolve "OtherService.promise". However, for certain routes, I would prefer to utilize a scope variable within the AppService method instead of the promise. How can I make this happen?

app.factory("AppService", function(OtherService){ 
    var object = {};
    object.method = function() {
        return OtherService.get();
    }
    return object; 
});

app.factory("OtherService", function($http) {
    var data = null;
    var promise = $http.get('/get').success(function (response) {
       data = response
    });
    return {
       promise: promise,
       get: function(){
           return data.html;
       }
 })

Answer №1

Update: I made some modifications to the service by including a new method and scope variable. To implement this in the controller, simply use AppService.setScope($scope).

I'm not entirely clear on your question, but perhaps this solution could work for you:

app.factory("AppService", function(OtherService){ 
    var scope = {};
    var object = {};
    object.method = function(mode) {
        return mode === 'promise' ? OtherService.get() : scope;
    }

    object.setScope = function(_scope) {
        scope = _scope;
    }
    return object; 
});


app.factory("OtherService", function($http) {
    var data = null;
    var promise = $http.get('/get').success(function (response) {
       data = response
    });
    return {
        promise: promise,
        get: function(){
            return data.html;
        }
 })

You might want to consider adding a validation check to ensure the retrieved data is valid when using the get function as an added precaution.

Promises are a valuable tool to prevent getting lost in callback hell. Attempting to make an asynchronous process synchronous is a path you should avoid at all costs.

Embrace the power of promises, as they greatly enhance readability. I recommend exploring the documentation for more information.
