Angular: how to destroy a promise

Question

In my word-cloud application I have 2 directives, a word cloud directive and table directive that when a word in the word cloud is selected, it notify to the table so the table will also select the correspond word. The word-cloud and the table communicate by promise which resides in the service, and I want to destroy the promise:

service code:

this.selectedDefferd = $q.defer(); 

this.selectedPromise = this.selectedDefferd.promise;

   notifySelect(id)
   {
        this.selectedDefferd.notify({newData: this.data[id]});
    }

 setSelect(callBack) {
    this.selectedPromise.then(null, null, callBack);
}

word cloud directive code :

d3.select(this).on("click", function (d) {
...
ctrl.wordService.notifySelect(d.id);
}

table directive

var selectCallback = $(".selected");

wordService.setSelect(selectCallback);

Thanks in advance,

Answer 1

With reject() you can reject a promise

this.selectedDefferd.reject('Rejected!');

The 2nd parameter of the promise is for the rejection.

promise.then(function(greeting) {
  alert('Success: ' + greeting);
}, function(reason) {
  alert('Failed: ' + reason);
}, function(update) {
  alert('Got notification: ' + update);
});
