在我的应用程序中，我有多个页面，我确实有一个普通模型，从普通模型中，我使用集合的parse方法根据页面扩展更多模型。
这样做之后，我仍然没有得到返回的集合，而是得到了我从后端检索的对象。
我的视图代码：
define([
"jquery",
"backbone",
"models/model",
"collection/dashBoardcollection",
"views/navi/naviView",
"views/dashBoard/myTaskView",
],function ($,Backbone,model,collection,naviView,myTaskView) {
var dashBoardView = Backbone.View.extend({
el:$("div.contentwrapper"),
events:{
"click h2" : "tileleDispaly"
},
initialize:function(){
this.$el.html(this.template);
this.c = collection;
this.listenTo(this.c, 'sync', this.logCollection);
this.c.fetch();
},
logCollection:function(){
console.log(this.c);
//not getting the collection shows array length as 1
},
tileleDispaly:function(e){
var tittle = $(e.target).text();
new myTaskView().showTitle(tittle);
}
});
return dashBoardView;
})
我的收藏代码：
define(["backbone","models/model"], function (Backbone,model) {
var titleModel = model.extend({
"title" : "no title assigned"
})
var slideModel = model.extend({
"slide" : "no title assigned"
})
var rowModel = model.extend({
"title" : "no title assigned",
"text" : "no text",
"date" : "define date"
})
var optionModel = model.extend({
"show" : "no title assigned"
})
var dashBoardCollection = Backbone.Collection.extend({
url:"js/dashBoard.json",
model:model,
initialize:function(model,options){
},
parse:function(response){
var that = this;
var x = [];
// update 1. pushing all models to x array
_.each(response.DashBoard, function(obj){
if(obj.hasOwnProperty("title")){
x.push(new titleModel(obj));
}else if (obj.hasOwnProperty("widget")){
_.each(obj.widget, function(m){
x.push(new slideModel(obj));
})
}else if (obj.hasOwnProperty("activity")){
_.each(obj.activity, function(va){
if(va.hasOwnProperty("rows")){
_.each(va.rows, function(row){
x.push(new rowModel(row));
})
}else if (va.hasOwnProperty("option")){
_.each(va.option, function(option){
x.push(new optionModel(option));
})
}
})
}
})
this.add(x);
//update 2. adding the models to collection
console.log(this);
// console works fine shows the array length as 12.
return this;
//returning to view..
}
});
return new dashBoardCollection;
})
但我的观点没有带来任何模型..从收藏中，这里有什么问题..？还是我的方法是错误的？任何人都可以帮我解决这个问题..？
