我对 Backbone 很陌生,只是想弄清楚事情的工作方式。如何遍历“获取”的结果?
(function($) {
console.log('Formcontainer init.');
var Field = Backbone.Model.extend({
defaults: {
id: "0",
memberlist_id: "3",
field_name: "sample-field-name",
},
initialize: function() {
console.log('Field model init.');
}
});
var FieldCollection = Backbone.Collection.extend({
defaults: {
model: Field
},
model: Field,
url: 'http://localhost:8888/getstuff/3.json',
initialize: function() {
console.log('FieldCollection init.');
}
});
var ListView = Backbone.View.extend({
el: '#app-container',
initialize: function() {
_.bindAll(this,"render");
console.log('ListView init.')
this.counter = 0;
this.collection = new FieldCollection();
this.collection.fetch();
//this.collection.bind('reset', function() { console.log('xxx')});
//this.collection.fetch();
this.render();
},
events: {
'click #add': 'addItem'
},
render: function() {
var self = this;
console.log('Render called.');
},
addItem: function() {
this.counter++;
this.$("ul").append("<li>hello world" + this.counter + "</li>");
}
});
var listView = new ListView();
})(jQuery);
我在我的 Firebug 控制台中得到了这个:
Formcontainer init.
ListView init.
FieldCollection init.
GET http://localhost:8888/getstuff/3.json 200 OK
Render called.
Field model init.
Field model init.
Field model init.
Field model init.
Field model init.
似乎调用了 fetch() - 因为“字段模型初始化”。在控制台中 5 次。但是我该如何输出呢?我想将项目附加到无序列表中。
谢谢!
