将解析注入指令控制器

Injecting resolves into directive controllers

我正在使用 AngularUI 路由器 (0.2.13) 并定义了一个状态

.state('foo', { 
    template:'<div some-directive></div>', 
    resolve: {
        foo: function(SomeService) {
            return SomeService.something().promise;
        }
    }
})

和这样的指令:

app.directive('someDirective', function(){
     return {
         controller: function(data) {
           // I want `data` to be injected from the resolve... 
           // as it would if this was a "standalone" controller
         }
     }
})

但这不起作用 - data 参数导致 UnknownProvider 错误。独立定义指令控制器和在指令中按名称设置结果相同。

我或多或少明白为什么会这样,但有两个问题:

  1. 有没有办法做我想做的事?
  2. 我应该尝试这样做,还是我在这里陷入了反模式?

你不能在指令中使用解析,但你可以将状态中解析的结果传递给我认为完成你正在寻找的指令。

您想更新状态定义以包含控制器并在指令上设置参数:

.state('foo', { 
   template:'Test<div some-directive something="foo"></div>',
   url: 'foo',
   resolve:{
       foo:function(SomeService){
           return SomeService.something();
       }
   },
   controller: function($scope, foo){
     $scope.foo = foo;
   }
})

然后更新指令以使用此参数:

.directive('someDirective', function(){
     return {
         controller: function($scope) {
           // I want `data` to be injected from the resolve... 
           // as it would if this was a "standalone" controller
           console.log('$scope.something: '+ $scope.something);
         },
         scope: {
           something: '='
         }
     };
})

他们简化了 api。查看此线程:

in 0.2.19 we are adding $resolve to the $scope, allowing you to do "route to component template" style

template: <my-directive input="$resolve.simpleObj"></my-directive>,
