Returning a value from a request within a function

Question

I am making a call from a controller in AngularJS, which passes data to a service to get a response in which I need to then check with a condition.

Controller

patents.forEach(function(item){ //patents is resolved in a router file which returns a number of items from a request item.renewalProgress = patentsService.phaseProgress(item); })

Service

factory.phaseProgress = function(item) { var progress = function(item) factory.fetchCostAnalysis(phase.id) .then( function(response){ var progress; switch(response.currentcostBand) { case 'Green': progress = 0; break; case 'Amber': progress = 20; break; case 'Red': progress = 40; break; case 'Blue': progress = 60; break; case ' progress = 80; } return progress }, function(errResponse){ console.log('no') } ) return progress; }

The value is coming back as undefined.

Question

How do I return a value to the controller from the service? If anyone can suggest a better approach even?

What is the case after blue? And where is your factory which you used inside the service? — Vivz

Did you close the case properly - case ' progress = 80; } return progress — Vinod kumar G

In your service you have an asynchronous function which returns a promise, that means when you get to that part, your process continues and that part of code inside then() will execute at a later time.

If you wish to WAIT for promise execution you can use Deffer from AngularJS.

Thank you. Handled the promise in the service and accessed the necessary data in the controller
