所以我正在建立一个移动网站,我有一个名为'api'的目录,其中包含从远程api返回JSON格式数据的各种php文件。我这样做是为了避免跨域问题。
但是其中一个php文件需要一个GET参数(即id),这样我就可以根据它的id回显特定对象的JSON数据。
我的集合将需要这样做(假设这将工作):
define([
'backbone',
'models/tournaments/single'
], function(Backbone, singleModel) {
var TournamentCollection = Backbone.Collection.extend({
model: singleModel,
url: '/api/tournament.php?id=' + id,
parse: function(response) {
return response;
}
});
return TournamentCollection;
});
我有这个在我的路由器,但我如何将'id'值传递给视图或集合:
define([
'jquery',
'underscore',
'backbone',
'views/home',
'views/tournament'
], function($, _, Backbone, HomeView, TournamentView) {
var AppRouter = Backbone.Router.extend({
routes: {
'': 'home',
'tournament/:id': 'tournament'
}
});
var initialize = function() {
var app_router = new AppRouter;
app_router.on('route:home', function() {
var homeView = new HomeView();
});
app_router.on('route:tournament', function(id) {
var tournamentView = new TournamentView({id: id});
});
Backbone.history.start();
};
return {
initialize: initialize
};
});
几点:
1)你对集合的url属性的定义将无法工作,因为在定义锦标赛集合类时可能没有定义id。您可以使用函数而不是属性。TournamentCollection会变成这样:
define([
'backbone',
'models/tournaments/single'
], function(Backbone, singleModel) {
var TournamentCollection = Backbone.Collection.extend({
model: singleModel,
initialize: function (options) {
this.id = options.id;
},
url: function () {
return '/api/tournament.php?id=' + this.id
},
parse: function(response) {
return response;
}
});
return TournamentCollection;
});
这样你就可以用一个id初始化对象,然后,当url被获取时,它将包含正确的id。
2)我可能会初始化并从路由器获取集合。然后从视图的初始化开始,等待取回完成并最终重新呈现视图。像这样:
define([
'jquery',
'underscore',
'backbone',
'views/home',
'views/tournament'
], function($, _, Backbone, HomeView, TournamentView) {
var AppRouter = Backbone.Router.extend({
routes: {
'': 'home',
'tournament/:id': 'tournament'
}
});
var initialize = function() {
var app_router = new AppRouter;
app_router.on('route:home', function() {
var homeView = new HomeView();
});
app_router.on('route:tournament', function(id) {
var tournaments = new TournamentCollection({ id: id });
tournaments.fetch();
var tournamentView = new TournamentView({ collection: tournaments });
});
Backbone.history.start();
};
return {
initialize: initialize
};
});
// Tournament View define stuff
var TournamentView = Backbone.View.extend({
initialize: function () {
this.listenTo(this.collection, 'sync', this.render);
},
render: function () {
//...
}
});
return TournamentView
希望有帮助。:)
