我的 Json 数组如下如何使用 Backbone 提取名称和临时

{
  "message": "accurate",
  "cod": "200",
  "count": 10,
  "list": [
    {
      "id": 495260,
      "name": "Shcherbinka",
      "coord": {
        "lon": 37.559719,

        }
      ]
    },

我的 JavaScript 如下:

<script>


      $(function() {
                var Profile = Backbone.Model.extend();

                var ProfileList = Backbone.Collection.extend({
                    model: Profile,
                    url: "http://api.openweathermap.org/data/2.5/find?lat=55.5&lon=37.5&cnt=10&appid=bd82977b86bf27fb59a04b61b657fb6f",     
                    parse : function(response){
                    weather_data = response.list
                    console.log(weather_data)
                        return weather_data;  
                   }   
                });   

                var ProfileView = Backbone.View.extend({
                    el: "#profiles",
                    template: _.template($('#profileTemplate').html()),
                    render: function(eventName) {
                        _.each(this.model.models, function(profile){
                            var profileTemplate = this.template(profile.toJSON());
                            $(this.el).append(profileTemplate);
                        }, this);

                        return this;
                    }
                });

                var profiles = new ProfileList();  
                profiles.fetch();
                var profilesView = new ProfileView({model: profiles});
                profiles.fetch({
                    success: function() {
                        profilesView.render();
                    }
                });

            });
        </script>

How to get Name and temperature from above Json

如果您打算访问“name”和“temp”，则在模型中设置它们后，可以按如下方式访问它们。

model.get("name");  //"Shcherbinka"
model.get("main").temp; //274.72
