What is the best way to retrieve the value of a property within a JavaScript object?

I am facing an issue with retrieving the value of the status property from an object in my code. Below is a snippet of what I have tried:

console.log("Resource.query()");
console.log(Resource.query());
console.log("Resource.query().status");
console.log(Resource.query().status);

Upon checking the Chrome console, it shows that Resource.query().status returns undefined, whereas Resource.query() returns the object itself. How can I successfully retrieve the value of status?

Any help would be greatly appreciated.

Answer №1

query() is performed asynchronously as highlighted in the tutorial (emphasis mine):

$scope.phones = Phone.query();

This code snippet simply requests all phone data to be queried. It's worth noting that no callback functions are passed when calling methods from our Phone service. Even though it may seem like the result is returned synchronously, that is not the actual scenario. What gets returned synchronously is a "future" — an object that will be populated with data once the XHR response is received. Thanks to Angular's data-binding feature, we can link this future object to our template. Consequently, when the data finally arrives, the view updates automatically.

Answer №2

Give this a shot: Resource.query()[0].status
