Backbone.js 主干.Paginator:无法读取属性';请求寻呼机';
类似于 我正在尝试实现版本0.8,在页面加载时遇到错误:UncaughtTypeError:无法读取未定义的属性'requestPager' 首先我引用了CDNJS文件,然后下载了原始代码并将其放在app/assets/javascripts中。我在application.js'/=require backbone.paginator.min.js'中也需要它 以下是位于application.html.erb中的my部分代码:Backbone.js 主干.Paginator:无法读取属性';请求寻呼机';,backbone.js,pagination,backbone.paginator,Backbone.js,Pagination,Backbone.paginator,类似于 我正在尝试实现版本0.8,在页面加载时遇到错误:UncaughtTypeError:无法读取未定义的属性'requestPager' 首先我引用了CDNJS文件,然后下载了原始代码并将其放在app/assets/javascripts中。我在application.js'/=require backbone.paginator.min.js'中也需要它 以下是位于application.html.erb中的my部分代码: <head> <title>D2jiv

位于我的路由器中,我指的是我的分页集合:
this.collection = new D2Jive.Collections.PaginatedCollections( [], { location: location });
然后,当Backbone.Paginator.requestPager的实际代码出现时,会弹出错误
D2Jive.Collections.PaginatedCollection = Backbone.Paginator.requestPager.extend({
initialize: function(attributes, options){
this.city = options.location;
},
我仍然习惯于JavaScript,但它似乎是主干。Paginator代码在window initialize函数创建新路由器并检查主干后加载。Paginator集合是我创建的。我只是不知道如何避免这种情况
出现错误后,我可以在控制台中加载Backbone.Paginator.requestPager
Backbone.Paginator.requestPager.extend
function (protoProps, staticProps) {
var parent = this;
var child;
// The constructor function for the new subclass is either defined by you
// (the "constructor" property in your `extend` definition), or defaulted
// by us to simply call the parent's constructor.
if (protoProps && _.has(protoProps, 'constructor')) {
child = protoProps.constructor;
} else {
child = function(){ return parent.apply(this, arguments); };
}
// Add static properties to the constructor function, if supplied.
_.extend(child, parent, staticProps);
// Set the prototype chain to inherit from `parent`, without calling
// `parent`'s constructor function.
var Surrogate = function(){ this.constructor = child; };
Surrogate.prototype = parent.prototype;
child.prototype = new Surrogate;
// Add prototype properties (instance properties) to the subclass,
// if supplied.
if (protoProps) _.extend(child.prototype, protoProps);
// Set a convenience property in case the parent's prototype is needed
// later.
child.__super__ = parent.prototype;
return child;
}
任何帮助都将不胜感激 启动应用程序之前,请确保包含主干分页器库。出现错误后可以访问
requestPager
的原因可能是因为在该阶段,库已经加载
为了确保代码没有问题,请尝试在页面的
部分包含主干分页器代码
根据评论进行编辑:
您需要更改“app/assets/javascripts/application.js”,使其以正确的顺序包含文件。比如:
//= require jquery
//= require jquery_ujs
//= require underscore
//= require backbone
//= require bacbkone.paginator.min
//= require_tree .
如果您仅仅依靠require_tree
来包含文件,那么它们不一定会以正确的顺序包含,这正是您所经历的
另外,由于主干分页器包含在应用程序文件中,因此它不应再包含在应用程序文件中。对不起,应该包含我的代码,我已编辑了上面的问题。如您所见,我在application.html.erb中引用了该文件。谢谢还是一样的错误。这一次,如果我交换行,我会得到错误“主干未定义”,因为分页器需要主干。因此,我在backbone.paginator上方添加了一行,其中添加了需要主干的application.js,然后“主干未定义”错误消失,但“无法读取未定义的属性'requestPager'错误仍然存在”。再次感谢您的帮助!是的,我忘了rails资产。。。我已经更新了我的答案:您的application.js需要以正确的顺序列出依赖项。
//= require jquery
//= require jquery_ujs
//= require underscore
//= require backbone
//= require bacbkone.paginator.min
//= require_tree .
