Question

我有以下代码。（我只需要复制路由器，因为此应用程序目前有500行）我需要的是从州'房间'切换到'guests.new'。

当我到达房间状态时，它会加载一个模板，我称之为动作'newGuest'，以便将状态更改为'newGuest'屏幕。但我无法让它发挥作用。在firebug上我得到了这个错误：

g[a] is undefined

这是路由器代码。希望你能帮帮我。

App.Router = Ember.Router.extend({
        enableLogging:true,
        location:'hash',
        gotoRooms:Ember.Route.transitionTo('rooms.index'),
        gotoGuests:Ember.Route.transitionTo('guests.index'),
        gotoBookings:Ember.Route.transitionTo('bookings'),
        gotoHome:Ember.Route.transitionTo('root.index'),

        root:Ember.Route.extend({
            index:Ember.Route.extend({
                route:'/',
                connectOutlets:function (router) {
                    App.HomeView.appendTo('#main-content .container_12');
                },
                enter: function(){
                    console.log('Entro Home');
                },
                exit: function(){
                    App.HomeView.remove();
                }
            }),
            guests:Ember.Route.extend({
                route:'/guests',
                index:Ember.Route.extend({
                    route:'/',
                    connectOutlets:function(router) {
                        App.GuestsView.appendTo('#main-content .container_12');    
                    },
                    enter: function(){
                        console.log("Entro Guests");
                    },
                    exit: function(){
                        App.GuestsView.remove();
                    },
                }),
                new:Ember.Route.extend({
                    route:'/new/:bed',
                    deserialize: function(manager, params) {
                        console.log('New Guest \nBed:'+params['bed']+"\n Date:"+params['date']);
                        App.GuestView.appendTo('#main-content .container_12');
                    },
                    connectOutlets:function(){
                        alert("hola");
                    },
                    exit: function(){
                        App.GuestsView.newGuestView.remove();
                    }
                })
            }),
            rooms:Ember.Route.extend({
                newGuest:Ember.Route.transitionTo('guests.new'),
                route:'/rooms',
                index:Ember.Route.extend({
                    route:'/',                    
                    connectOutlets:function(router) {
                        App.RoomsView.appendTo('#main-content .container_12');    
                    },
                    enter: function(){
                        console.log("Entro Rooms");
                    },
                    exit: function(){
                        App.RoomsView.remove();
                    }
                })
            })
        })
    });

谢谢@Akash，但它仍然没有用。我正在使用ember-1.0.pre。调用'newGuest'的模板如下：

  <script type="text/x-handlebars" data-template-name="rooms">
      {{#each room in App.Rooms}}
        <div class="grid_4">
      <div class="block-border">
        <div class="block-header">
          <h1>{{room.screen}}</h1><span></span>
        </div>
        <div class="block-content">
          <ul class="block-list">
          {{#each bed in room.camas}}
            {{#if bed.guestId}}
            <li {{action "viewGuest" on="click"}} class="occupied">{{bed.id_guest}}</li>
            {{else}}
            <li class="free" {{action "newGuest" on="click"}}>Free Bed</li>
            {{/if}}
          {{/each}}
          </ul>
        </div>
      </div>
    </div>
      {{/each}}
    </script>

我也尝试过使用ember-latest，因为我已经在各种线程中读到了预版本给出了一些路由问题。事实证明，使用ember-latest，我无法定义计算属性。至少这是加载页面时控制台上弹出的内容。

有任何线索吗？

非常感谢！

问题在于，Ember无法访问guests路线中的rooms路线。所以你需要做的是将动作功能向下移动到树下。我在下面调整了你的代码：

调整代码：

App.Router = Ember.Router.extend({
        enableLogging:true,
        location:'hash',
        gotoRooms:Ember.Route.transitionTo('rooms.index'),
        gotoGuests:Ember.Route.transitionTo('guests.index'),
        gotoBookings:Ember.Route.transitionTo('bookings'),
        gotoHome:Ember.Route.transitionTo('root.index'),

        root:Ember.Route.extend({
            newGuest:Ember.Route.transitionTo('guests.new'),
            index:Ember.Route.extend({
                route:'/',
                connectOutlets:function (router) {
                    App.HomeView.appendTo('#main-content .container_12');
                },
                enter: function(){
                    console.log('Entro Home');
                },
                exit: function(){
                    App.HomeView.remove();
                }
            }),
            guests:Ember.Route.extend({
                route:'/guests',
                index:Ember.Route.extend({
                    route:'/',
                    connectOutlets:function(router) {
                        App.GuestsView.appendTo('#main-content .container_12');    
                    },
                    enter: function(){
                        console.log("Entro Guests");
                    },
                    exit: function(){
                        App.GuestsView.remove();
                    },
                }),
                new:Ember.Route.extend({
                    route:'/new/:bed',
                    deserialize: function(manager, params) {
                        console.log('New Guest \nBed:'+params['bed']+"\n Date:"+params['date']);
                        App.GuestView.appendTo('#main-content .container_12');
                    },
                    connectOutlets:function(){
                        alert("hola");
                    },
                    exit: function(){
                        App.GuestsView.newGuestView.remove();
                    }
                })
            }),
            rooms:Ember.Route.extend({
                route:'/rooms',
                index:Ember.Route.extend({
                    route:'/',                    
                    connectOutlets:function(router) {
                        App.RoomsView.appendTo('#main-content .container_12');    
                    },
                    enter: function(){
                        console.log("Entro Rooms");
                    },
                    exit: function(){
                        App.RoomsView.remove();
                    }
