Question

我想从视图＃1调用一个已经在不同视图中实现的方法（视图＃2）。如何以一种简单的方式实现这一点..使用backbonejs。

App.Views.view1 = Backbone.View.extend({
   events: {
       'click .someclass1' : 'custom_method_1',
         },

        custom_method_1:function(e){

         //now this method calls another method which is implemented in different view
         custom_method_2();
    },
});


 App.Views.view2 = Backbone.View.extend({
   events: {
       'click .someclass2' : 'custom_method_2',
         },

   //// this method needs to be called from view1 also
        custom_method_2:function(e){

    },
});

如果您搜索如何使用eventbus，您可以这样做：

// you can name the event 'custom_method_2' as you want
Backbone.Events.on('custom_method_2', App.Views.view2.custom_method_2);

现在，您正在收听对象custom_method_2上的事件Backbone.Events，您可以将其视为事件总线。

然后在view1：

custom_method_1:function(e){

     //now this method calls another method which is implemented in different view
     // custom_method_2();
     Backbone.Events.trigger('custom_method_2', e);
},

如何使用另一个视图中的视图中实现的方法：backbonejs
