Backbone.js - 将 2 个模型传递给 1 个视图 [英] Backbone.js - passing 2 models to 1 view

问题描述

我正在尝试将 2 个模型传递给视图，但它似乎不起作用.这是我的例子:http://jsfiddle.net/kahhor/jp4B6/14/ As您可以看到第二个警报显示未定义...

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...

可能是我的方法不对.我想要做的是:在 View1 绑定事件 'change' 到 Model1 ... 比点击 中的按钮View2，调用Model1中改变值的函数，自动渲染View1，因为它绑定了change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 View2 也有它自己的 Model2，它是我在视图之外创建的，然后像 new View2({model: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});.

一开始可能看起来很混乱，但我认为主干可以做的很简单.我只是不知道该怎么做:)

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});

像这样:

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:可以在this.options
