访问 Javascript 对象的值

Question

I am working with a function that returns a value to a variable. When i console log the variable it shows what your seen in the image. i need to get access to the value so I can display it to the user how can i do this?

this is my code function save(user) {

        var response= Restangular.all('admin').post(user).then(function (postedUser) {

            return postedUser;

        });

        console.log(response);
        return response;
    }

Answer 1

reponse is a promise . You can't (or should not be able to) access the value of a promises directly, since the promise might not be resolved yet.

Instead, you have to pass a callback to the promise. When the promise is resolved with a value, it passes that value to all attached callbacks. In your example, the promise will eventually be resolved with value of postedUser .

The function that calls save can access the value like so:

save(...).then(function(value) {
  // do something with value here
});

Note: You can drop the .then inside the function and simplify it to

function save(user) {
    return Restangular.all('admin').post(user);
}

since you are passing the identity function to .then .
