无法遍历骨干网集合 [英] Can't loop over backbone collection

问题描述

看来我无法遍历一个骨干网集合.我已经在多个线程中看到了该主题，但是这些解决方案都无济于事.

It seems that I can't loop through a backbone collection. I've seen this topic in several threads, but none of those solutions help.

render:function () {
        this.$el.html(this.template(this.model.attributes));
        var that = this;


        console.log(this.projects.models);
        _.each(this.projects.models, function(model) { console.log(model); });

        return this;
    }

从此，我的控制台仅显示Array [2] 我希望也会看到每个模型. 有人知道我在做什么错吗?

From this my console only shows Array[2] I would expect to see each model as well. Does anyone know what I'm doing wrong here ?

推荐答案

要以数组形式获取集合内容，请使用方法toJSON(例如:collection.toJSON())

To get your collection content as an array, use the method toJSON (e.g.: collection.toJSON())

接下来，要遍历整个集合，请在集合实例上使用each方法！

Next, to loop over your entire collection, use the each method on the collection instances!

collection.each(function( model ) {
    console.log(model)
});

如果没有显示完整的收藏夹，那么问题就出在如何在收藏夹中添加项目，而不是循环逻辑中.

If this don't show your full collection, then the problem is in how you add items inside your collection, not in the looping logic.
