如何使用角度無級控制器的CoffeeScript「這個」：

Question

我很好奇，爲什麼下面不工作，我以爲是我不理解的CoffeeScript：

angular.module('clientApp') 
 
    .controller 'FoobarCtrl', ($scope) -> 
 

 
    console.log "Foobar controller" 
 

 
    $scope.content = "message from foobar" 
 

 
    @output =() -> 
 
     return "returned message from coffee controller"

我以爲上面會相當於：

angular.module('clientApp') 
 
    .controller('FoobazCtrl', function ($scope) { 
 

 
    console.log("Foobar controller") 
 

 
    $scope.content = "message from foobar"; 
 

 
    this.output = function(){ 
 
     return("returned message from coffee controller"); 
 
    } 
 

 
    });

但它似乎不是。誰能告訴我哪裏出了問題？

等效是：

angular.module("clientApp").controller "FoobazCtrl", ($scope) -> 
    console.log "Foobar controller" 
    $scope.content = "message from foobar" 
    @output = -> 
    "returned message from coffee controller" 

    return 

你coffescript代碼生成此javascript：

angular.module('clientApp').controller('FoobarCtrl', function($scope) { 
    console.log("Foobar controller"); 
    $scope.content = "message from foobar"; 
    return this.output = function() { 
    return "returned message from coffee controller"; 
    }; 
});
