I made an autocomplete directive and uploaded it to GitHub. It should also be able to handle data from an HTTP-Request.
Here's the demo: http://justgoscha.github.io/allmighty-autocomplete/ And here the documentation and repository: https://github.com/JustGoscha/allmighty-autocomplete
So basically you have to return a promise when you want to get data from an HTTP request, that gets resolved when the data is loaded. Therefore you have to inject the $qservice/directive/controller where you issue your HTTP Request.
Example:
function getMyHttpData(){
var deferred = $q.defer();
$http.jsonp(request).success(function(data){
// the promise gets resolved with the data from HTTP
deferred.resolve(data);
});
// return the promise
return deferred.promise;
}
I hope this helps.
