我遇到的问题是Stack中有很多其他帖子.但是没有人能解决这个问题所以我正在解决这个问题.
快速参考：
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.这是我遵循的例子：
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
(anonymous function)/backbone/#:32
f.extend._Deferred.e.resolveWithjquery-1.6.4.min.js:2
e.extend.readyjquery-1.6.4.min.js:2
c.addEventListener.C
检查我的代码：

<html>
<head>
<title></title>
<link href="css/style.css" media="all" rel="stylesheet" type="text/css" />
</head>
<body>

});
</script>
</body>
</html>
类别：
App.Collections.Documents = Backbone.Collection.extend({
model: Document,
url: '/documents'
});
控制器：
App.Controllers.Documents = Backbone.Controller.extend({
routes: {
"documents/:id": "edit",
"": "index",
"new": "newDoc"
},
edit: function(id) {
var doc = new Document({ id: id });
doc.fetch({
success: function(model, resp) {
new App.Views.Edit({ model: doc });
},
error: function() {
new Error({ message: 'Could not find that document.' });
window.location.hash = '#';
}
});
},
index: function() {
var documents = new App.Collections.Documents();
documents.fetch({
success: function() {
new App.Views.Index({ collection: documents });
},
error: function() {
new Error({ message: "Error loading documents." });
}
});
},
newDoc: function() {
new App.Views.Edit({ model: new Document() });
}
});
楷模：
var Document = Backbone.Model.extend({
url : function() {
var base = 'documents';
if (this.isNew()) return base;
return base + (base.charAt(base.length - 1) == '/' ? '' : '/') + this.id;
}
});
浏览次数：
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);
}
});
notice.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.'
});
该应用程序：
var App = {
Views: {},
Controllers: {},
Collections: {},
init: function() {
new App.Controllers.Documents();
Backbone.history.start();
}
};
解决方法:
如果您使用的是主干0.5.x,则将Backbone.Controller重命名为Backbone.Router
从文档：
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.
