骨幹好模型結構

Question

我想知道你對這個結構的看法。您在同一頁面中有3個或4個部分。並且您使用主模型來控制另一個模型之間的通信。我在想這是重用de代碼的好習慣。你怎麼看待這件事？

 mainModel(comunication betwen submodel) 
    / | \ 
model model model 

謝謝

我喜歡通過擴展Backbone.Events創建一箇中介...

var App = {}; 
App.Events = _.extend({}, Backbone.Events); 

var MainModel = Backbone.Model.extend({ 
    initialize: function() { 
     App.Events.trigger("my.event"); 
    } 
}); 

var ModelA = Backbone.Model.extend({ 
    initialize: function() { 
     App.Events.on("my.event" this.onEvent, this); 
    }, 
    onEvent: function() {} 
}); 
var ModelB = Backbone.Model.extend({ 
    initialize: function() { 
     App.Events.on("my.event" this.onEvent, this); 
    }, 
    onEvent: function() {} 
});
