在骨干网做鉴于混入有道 [英] Proper way of doing view mixins in Backbone

问题描述

我延长基地骨干认为所有的时间，并且每个部分基本观点，这样我可以在多个层次上延伸。我的问题是，什么是做视图混入的最有效的方法：可重复使用的视图的谐音，可以在任何视图混合。例如：

I extend base backbone views all the time and have a base view per section so that I can extend on multiple levels. My question is, what's the most effective way of doing view mixins: reusable view partials that can be mixed in to any view. For example:

var BaseProfile = Backbone.View.extend({ ...});
var UserProfile = BaseProfile.extend({ ...});
var VideoSupport = Backbone.View.extend({ ...});

什么是混入 VideoSupport 视图（事件对象和几个方法）与用户配置视图的最佳方法是什么？

What's the best way to mixin VideoSupport view (an event object and a few methods) with UserProfile view?

推荐答案

该underscore.js库提供了一个延长方法你想要做什么。您可以在任何物体上定义的功能，然后毫不夸张地复制和放大器;粘贴所有的方法，并从该对象属性到另一个

The underscore.js library provides an extend method that does what you want. You can define functionality on any object, and then quite literally copy & paste all of the methods and attributes from that object to another.

骨干延长的意见，模型和路由器的方法是围绕下划线的一个包装延长。

Backbone's extend methods on Views, Models, and Routers are a wrapper around underscore's extend.

 var MyMixin = {
  foo: "bar",
  sayFoo: function(){alert(this.foo);}
}

var MyView = Backbone.View.extend({
 // ...
});

_.extend(MyView.prototype, MyMixin);

myView = new MyView();
myView.sayFoo(); //=> "bar"
