Backbone.js的 - 经过2模型1视图 [英] Backbone.js - passing 2 models to 1 view

问题描述

我想2模型传递给视图，但现在看来，这是行不通的。这里是我的例子： http://jsfiddle.net/kahhor/jp4B6/14/ 正如你可以看到第二个警告正显示出不确定...

I'm trying to pass 2 models to the view, but it seems it is not working. Here is my example: http://jsfiddle.net/kahhor/jp4B6/14/ As you can see second alert is showing undefined...

可能是我有错误的做法。我正在试图做的是：在视图1 绑定事件改变到型号1 ...比通过点击视图2按钮在型号1 通话功能，改变价值，并自动渲染视图1 ，因为它被绑定到更改事件。

May be I have wrong approach. What I'm trying to do is: in View1 bind event 'change' to Model1... Than by clicking button in View2, call function in Model1 which changes value, and automatically render View1, since it was binded to change event.

但是，不要忘记，视图2 也有其自身的模型2 ，这是我的观点之外，比创建通过它像新视图2（{模型：模型2}）;

But don't forget that View2 has also its own Model2, which I created outside the view and than passed it like new View2({model:Model2});.

这也许看了第一混乱，但我认为这是简单的事情，骨干网可以做。我只是不知道如何做到这一点：）

It might looked confusing at first, but I think it is simple thing that backbone can do. I just don't know how to do it :)

谢谢，

推荐答案

您可以从

window.PopupView = new PopupView({ model: LeftNotificationM, model2: PopupM});

是这样的：

window.PopupView = Backbone.View.extend({

    // code left out

    initialize: function () {
        this.model.bind('change:notification_num', this.render);
        alert(this.model);
        // your model2 option:
        alert(this.options.model2);
    },

   // code left out
});

结论：鉴于识别的选项可以在 this.options
