我遇到一个问题，因为 Stack 中还有很多其他帖子。但是没有人解决这个问题，所以我把这个问题收回来。
快速引用: Uncaught TypeError: undefined is not a function rails3/backbone/js
我正在用 backBoneJs 编写我的第一个应用程序。这是我正在关注的示例:
http://www.jamesyu.org/2011/01/27/cloudedit-a-backbone-js-tutorial-by-example/
当我执行代码时:
1 - Uncaught TypeError: Cannot call method 'extend' of undefined (Controller 1ºline)
2 - Uncaught TypeError: undefined is not a function (app 6º line)
App.initapp.js:6

集合:
App.Collections.Documents = Backbone.Collection.extend({
model: Document,
url: '/documents'
});
Controller :
App.Controllers.Documents = Backbone.Controller.extend({
routes: {
"documents/:id": "edit",
"": "index",
"new": "newDoc"
},
edit: function(id) {
var doc = new Document({ id: id });
doc.fetch({

new App.Views.Edit({ model: doc });
},
error: function() {
new Error({ message: 'Could not find that document.' });

},
error: function() {
new Error({ message: "Error loading documents." });
}
});
},
newDoc: function() {
new App.Views.Edit({ model: new Document() });
}
});
模型:
var Document = Backbone.Model.extend({
url : function() {
var base = 'documents';
if (this.isNew()) return base;
return base + (base.charAt(base.length - 1) == '/' ? '' : '/') + this.id;
}
});
观看次数:
edit.js
App.Views.Edit = Backbone.View.extend({
events: {
"submit form": "save"
},
initialize: function() {
_.bindAll(this, 'render');
this.model.bind('change', this.render);
this.render();
},
save: function() {
var self = this;
var msg = this.model.isNew() ? 'Successfully created!' : "Saved!";
this.model.save({ title: this.$('[name=title]').val(), body: this.$('[name=body]').val() }, {
success: function(model, resp) {
new App.Views.Notice({ message: msg });
Backbone.history.saveLocation('documents/' + model.id);
},
error: function() {
new App.Views.Error();
}
});
return false;
},
render: function() {
$(this.el).html(JST.document({ model: this.model }));
$('#app').html(this.el);
// use val to fill in title, for security reasons
this.$('[name=title]').val(this.model.get('title'));
this.delegateEvents();
}
});
index.js
App.Views.Index = Backbone.View.extend({
initialize: function() {
this.render();
},
render: function() {
$(this.el).html(JST.documents_collection({ collection: this.collection }));
$('#app').html(this.el);
}
});
通知.js
App.Views.Notice = Backbone.View.extend({
className: "success",
displayLength: 5000,
defaultMessage: '',
initialize: function() {
_.bindAll(this, 'render');
this.message = this.options.message || this.defaultMessage;
this.render();
},
render: function() {
var view = this;
$(this.el).html(this.message);
$(this.el).hide();
$('#notice').html(this.el);
$(this.el).slideDown();
$.doTimeout(this.displayLength, function() {
$(view.el).slideUp();
$.doTimeout(2000, function() {
view.remove();
});
});
return this;
}
});
App.Views.Error = App.Views.Notice.extend({
className: "error",
defaultMessage: 'Uh oh! Something went wrong. Please try again.'
});
应用:
var App = {
Views: {},
Controllers: {},
Collections: {},
init: function() {
new App.Controllers.Documents();
Backbone.history.start();
}
};
最佳答案
如果您使用的是 backbone 0.5.x，则 Backbone.Controller 已重命名为 Backbone.Router
来自文档:
Upgrading to 0.5.0+
We've taken the opportunity to clarify some naming with the 0.5.0 release. Controller is now Router, and refresh is now reset. The previous saveLocation and setLocation functions have been replaced by navigate. Backbone.sync's method signature has changed to allow the passing of arbitrary options to jQuery.ajax. Be sure to opt-in to pushState support, if you want to use it.
