如何在Backbone中爲多個視圖重用渲染函數？

Question

我工作骨幹的應用程序，我有一個具有相同的功能呈現多個視圖：

render: function(){ 
    this.$el.html(this.template(this.model.toJSON())); 
    return this; 
} 

如何重用在多個視圖中此功能，所以我可以沿用老的幹法？

Answer 1

您可以使用這裏指定的混入模式：Proper way of doing view mixins in Backbone

var renderable = { 
    render: function(){ 
     this.$el.html(this.template(this.model.toJSON())); 
     return this; 
    } 
}; 

var view = Backbone.View.extend({ 
//other methods 
}); 

_.extend(view.prototype, renderable); 

var myView = new view(); 
myView.render();

延長另一種觀點認爲

var BeefedupView = Backbone.View.extend({ 
    render: function() { 
     this.$el.html(this.template(this.model.toJSON())); 
     return this; 
    } 
}); 

var myView = BeefedupView.extend({ 
    // Do super cool stuff here... 
});
