{
"code":"OK",
"message":"Success",
"errorFlag":"N",
"errors":null,
"data": {
"images": {
0: img0,
1: img1,
2: img2
}
}
}
这是一个REST响应,我想将“图像”记录放在我的集合中,并将每个单独的记录视为模型。
var Image.Model = Backbone.Model.extend({});
var Image.Collection = Backbone.Collection.extend({
model: Image.Model,
url: 'rest/url'
});
var images = new Image.TestCollection();
images.fetch();
如何让“images”中的记录成为图像集的唯一模型,并将代码,消息,错误等键放到另一个模型或集合中?
谢谢。

使用http://backbonejs.org/#Collection-parse
// server.js
app.get('/api/data', function (req, res) {
var result = {
"code": "OK",
"message": "Success",
"errorFlag": "N",
"errors": null,
"data": {
"images": {
0: "img0",
1: "img1",
2: "img2"
}
}
};
res.json(result);
});
// client.js
var Image = Image || {};
Image.Model = Backbone.Model.extend({
});
Image.TestCollection = Backbone.Collection.extend({
model: Image.Model,
url: '/api/data',
parse: function(response) {
window.response =response;
var images= [];
for(var key in response.data.images){
if(response.data.images.hasOwnProperty(key)){
images.push(response.data.images[key]);
}
}
return images;
}
});
var images = new Image.TestCollection();
images.fetch();
P.S。将数据存储在密钥中通常是个坏主意。
