How do I make scope destroy event to wait for the promise to resolve ?

[Rahul Tokase]

Hi 

I have written a directive in which on destroy event i need to call some AJAX request and I want my destroy event to wait for the AJAX call to finished.

Here is my code.

scope.$on('$destroy', function() {                   

                     

                        callmethodAsync("").always(function() {

                            // Do some cleanup or logging

                            console.log('inside remember');

                        });

                       

                });

Here i want my destroy method to wait for asyn method execution. How I can achieved that.

Hi Rahul,

You can't wait there. The function will get destroyed as soon as it runs to completion.  However, you can take the function you need out of the current event loop, and elevate it to the next using setTimeout. (or, if you need to update anything on screen use the $timer) You can do that like this:

scope.$on('$destroy', function () {

setTimeout(function anonymous() { // When the function eeds to change something in the $scope, use $timer instead

callmethodAsync("").always(function () {

// Do some cleanup or logging

console.log('inside remember');

});

}, 0)

});
