尽管阅读了有关此问题的各种解决方案并进行了尝试,但我仍在努力访问我收藏的模型-显然有些东西我没有得到-请帮助!
我有一个集合,其中数据来自 XML 文件,如下所示:
define([
'underscore',
'backbone',
'localstorage',
'models/script/ScriptModel'
], function(_, Backbone, LocalStorage, ScriptModel) {
var ScriptsCollection = Backbone.Collection.extend({
model : ScriptModel,
url: '/data/script.xml',
parse: function (data) {
var parsed = [];
$(data).find('play').each(function (index) {
var title = $(this).find('title').text();
var author = $(this).find('author').text();
parsed.push({
title: title,
author: author
});
});
return parsed;
},
fetch: function (options) {
options = options || {};
options.dataType = "xml";
return Backbone.Collection.prototype.fetch.call(this, options);
}
});
return ScriptsCollection;
});
这一切似乎都正常,然后在我看来,我做了以下事情:
define([
'jquery',
'underscore',
'backbone',
'views/settings/SettingsView',
'models/script/ScriptModel',
'collections/scripts/ScriptsCollection',
'text!templates/script/scriptTemplate.html'
],
function($, _, Backbone, SettingsView, ScriptModel, ScriptsCollection, scriptTemplate) {
var ScriptView = Backbone.View.extend({
el : $("#container"),
initialize: function(){
this.collection = new ScriptsCollection();
this.collection.fetch();
},
render : function() {
this.$el.html(scriptTemplate);
//add the settings view
var settingsView = new SettingsView();
settingsView.render();
}
});
return ScriptView;
});
现在,如果我控制台日志“this.collection”,我可以看到:
child {length: 0, models: Array[0], _byId: Object, constructor: function, model: function…}
_byId: Object
length: 1
models: Array[1]
0: child
_changing: false
_events: Object
_pending: false
_previousAttributes: Object
attributes: Object
author: "Eric and Ernie"
title: "The Play Wot I Wrote"
__proto__: Object
changed: Object
cid: "c3"
collection: child
__proto__: Surrogate
length: 1
__proto__: Array[0]
__proto__: Surrogate
在“模型”中,我可以在“属性”中看到我的数据,但如果我记录“this.collection.models”,我会看到一个空数组。我还可以看到模型的长度为 0,所以我对此感到困惑??
我似乎无法弄清楚为什么会这样,尽管我的猜测是我只是在这里遗漏了一些基本的东西?- 我害怕骨干菜鸟!
任何想法............任何人?
