How do I make sure I'm using Kris Kowal's Q instead of jQuery's Deferred
implementation? Injecting $q using
app.factory('someservice', ['$http', '$q', function ($http, $q) {...
Injects the $q. However, I can only get jQuery's Deferred implementation.
So I can't do as shown in the documentation
<https://docs.angularjs.org/api/ng/service/$q>, I get the error
*TypeError: $q is not a function*
// for the purpose of this example let's assume that variables `$q` and
`okToGreet`
// are available in the current lexical scope (they could have been injected or
passed in).
function asyncGreet(name) {
// perform some asynchronous operation, resolve or reject the promise when
appropriate.
return $q(function(resolve, reject) {
setTimeout(function() {
if (okToGreet(name)) {
resolve('Hello, ' + name + '!');
} else {
reject('Greeting ' + name + ' is not allowed.');
}
}, 1000);
});
}
var promise = asyncGreet('Robin Hood');
promise.then(function(greeting) {
alert('Success: ' + greeting);
}, function(reason) {
alert('Failed: ' + reason);
});
But I can do
// for the purpose of this example let's assume that variables `$q` and
`okToGreet`
// are available in the current lexical scope (they could have been injected or
passed in).
function asyncGreet(name) {
var deferred = $q.defer();
setTimeout(function() {
deferred.notify('About to greet ' + name + '.');
if (okToGreet(name)) {
deferred.resolve('Hello, ' + name + '!');
} else {
deferred.reject('Greeting ' + name + ' is not allowed.');
}
}, 1000);
return deferred.promise;
}
var promise = asyncGreet('Robin Hood');
promise.then(function(greeting) {
alert('Success: ' + greeting);
}, function(reason) {
alert('Failed: ' + reason);
}, function(update) {
alert('Got notification: ' + update);
});
When I do *console.log($q)*, I see that it has only has fuctions
- all(promises)
- defer:()
- reject:(reason)
-
- when:(value, callback, errback, progressback)
*NB: I am using angular 1.5.8.*
