我如何通过属性来一个骨干看法？ [英] How do I pass properties to a Backbone view?

问题描述

我是开发利用骨干V1.0.0我的应用程序之间开始工作，现在已经更新到V1.1.0。那么，我曾经是能够做到的，

I was developing my app using Backbone v1.0.0 and between beginning work and now there has been an update to v1.1.0. So where I used to be able to do,

var myView = new MyView({hash: 'something'});

和访问散视图内使用，

this.options.hash

这不再起作用。我现在得到以下错误：

This no longer works. I now get the following error:

遗漏的类型错误：无法读取的未定义的属性哈希

Uncaught TypeError: Cannot read property 'hash' of undefined

那么，这样做的新途径？我非常希望能够将属性传递到我的看法。

So what's the new way of doing this? I would very much like to be able to pass properties into my view.

推荐答案

从 1.1.0更新日志：

  
• 骨干浏览不再自动连接传递给构造选项 this.options ，但你可以，如果你自己做preFER。

  

• Backbone Views no longer automatically attach options passed to the constructor as this.options, but you can do it yourself if you prefer.

所以构造选项仍然传递到初始化，但 this.options 不再自动设置。你可以这样做：

So the constructor options are still passed to initialize but this.options is no longer automatically set up. You can do this:

initialize: function(options) {
    // Stash `options.hash` in `this` if you want or
    // `this.options = options;` if you want to emulate
    // the old behavior.
}
