如何将属性传递给Backbone视图？

Question

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'});

And access hash inside the view using,

this.options.hash

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

Uncaught TypeError: Cannot read property 'hash' of undefined

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

From the 1.1.0 ChangeLog :

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

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.
}
