AngularJS中处理多个promise

var app = angular.module("app",[]);

app.controller("AppCtrl", function($q. $timeout){
    var one = $q.defer();
    var two = $q.defer();
    var three = $q.defer();
    
    $timeout(function(){
        one.resolve("one done");
    }, Math.random() * 1000)
    
    $timeout(function(){
        two.resolve("two done");
    }, Math.random() * 1000)  
    
    $timeout(function(){
        three.resolve("three done");
    }, Math.random() * 1000)    
    
    functioin success(data){
        console.log(data);
    }
    
    one.promise.then(success);
    two.promise.then(success);
    three.promise.then(success);
})
