Backbone.js 分组集合

发布于 2024-12-21 08:13:58 字数 264 浏览 0 评论 0原文

我有一个包含男性和女性模型的backbone.js 集合。

在我的界面中，我想将它们分成各自的列。是否有内置/推荐的方法在backbone.js集合中进行分组？

现在在我的视图/渲染代码中我正在做

if male
  self.el.appendTo(#male)
if female
  self.el.appendTo(#female)

还有其他方法吗？也许使用下划线的groupBy？

谢谢。

原文

I have a backbone.js collection with male and female models.

In my interface I want to separate them into their own individual columns. Is there a built in / recommended way to group in backbone.js collection?

Right now in my view / rendering code I'm doing

if male
  self.el.appendTo(#male)
if female
  self.el.appendTo(#female)

Is there any other way of doing it? Maybe using underscore's groupBy?

Thanks.

您可以按性别过滤集合以获得匹配模型的数组

Person = Backbone.Model.extend();
Persons = Backbone.Collection.extend({
    model: Person,
    filterGender: function (g) {
        return this.filter(function(m) {
            return m.get("gender")==g;
        });
    }
});

l=new Persons();
l.add({gender:'female',id:1});
l.add({gender:'female',id:2});
l.add({gender:'male',id:3});

console.log(l.filterGender("female"));

You could filter the collection by gender to get an array of the matching models

Person = Backbone.Model.extend();
Persons = Backbone.Collection.extend({
    model: Person,
    filterGender: function (g) {
        return this.filter(function(m) {
            return m.get("gender")==g;
        });
    }
});

l=new Persons();
l.add({gender:'female',id:1});
l.add({gender:'female',id:2});
l.add({gender:'male',id:3});

console.log(l.filterGender("female"));
