$q对异步操作进行功能扩展。


var m1 = angular.module('myApp',[]);
m1.controller('Aaa',['$scope','$q',function($scope,$q){
    
    var dfd = $q.defer();//创建延迟对象    
    function show(){
        setTimeout(function(){            
            dfd.reject();//失败时候触发            
        },2000);
        return dfd.promise;
    }    
    show().then(function(){
        alert('成功');
    },function(){
        alert('失败');
    });    
}]);
</script>
</head>

<body>
<div ng-controller="Aaa">
</div>
</body>
</html>
