EmberJS - 如何过滤数组并通过路由器将其传递给模板 [英] EmberJS - How to filter array and pass it to template via router

问题描述

看到这个 jsFiddle 。

我有这样的数组。

App.Fields = [{id: "Gender", desc: "Male", key: "M"}, 
                  {id: "Gender", desc: "Female", key: "F"}, 
                  {id: "Martial Status", desc: "Single", key: "S"}, 
                  {id: "Martial Status", desc: "Married", key: "M"}];   

当我的路由器执行时，我想通过基于过滤的数组的model.id。以下是我的路由器。

While my router executes i want to pass filtered array based model.id. Below is my router.

App.FieldRoute = Ember.Route.extend({
  setupController: function(controller, Field) {
    controller.set('model', App.Fields);
  }
});

当用户点击Gender时，我想从上述数组过滤id =Gender的对象。

When user clicks "Gender" i want to filter objects having id = "Gender" from the above array.

FYI：model.id将给出性别。

FYI: model.id will give "Gender".

推荐答案

您还可以使用.filterProperty（）返回匹配属性的数组

You could also use .filterProperty() which returns the array with the matched property

controller.set('model', App.Fields.filterProperty('id',model.id));

也会做窍门
