骨架.js-更改或点击事件未触发
[英]backbone.js - change or click events not firing
问题描述
I am getting started with backbone.js but it seems i am not able to get the first hand code correct. 
我正在开始使用bone.js，但似乎无法正确掌握第一手代码。 I looked up all the resources but cant figure out what is the problem. 我查找了所有资源，但无法找出问题所在。
I was expecting changed event getting fired every time i change something in the input box and finally when i click the button, it should fire someAction function. 我期望每次更改输入框中的内容时都会触发更改的事件，最后，当我单击按钮时，它应该触发someAction函数。 There are no JavaScript errors but nothing happens. 没有JavaScript错误，但没有任何反应。 no change or click event getting fired. 没有更改或点击事件被触发。
Can someone please tell me what am i missing here? 有人可以告诉我我在这里想念什么吗？

All of your functionality should be in a view not a model. 您的所有功能都应该在视图中而不是模型中。
Change Person = Backbone.Model.extend to PersonView = Backbone.View.extend . 将Person = Backbone.Model.extend更改为PersonView = Backbone.View.extend 。 Now you actually have to create an instance of the view. 现在，您实际上必须创建视图的实例。
$(function() {
PersonView = Backbone.View.extend({
...
});
window.personview = new PersonView();
});

_.bindAll(this, "changed"); won't bind to the changed event. 不会绑定到更改后的事件。 You need to add 'change input': 'changed' to your events list. 您需要在事件列表中添加'change input': 'changed' 。 The bindAll isn't needed at all. 完全不需要bindAll。
Also, I believe this.model is undefined. 另外，我相信this.model是未定义的。 I think you should be using this.set(data) instead of this.model.set(data) . 我认为您应该使用this.set(data)而不是this.model.set(data) 。
