需要错误的依赖顺序

Question

我有一个变量保存在js文件中：子类别.js。像这样的东西(但实际上要大得多(：

define({
subcategories: { 
"Category1":
[
"Subcategory1-1", "Subcategory1-2", "Subcategory1-3"
],
"Electrical":
[
"Subcategory2-1", "Subcategory2-2", "Subcategory2-3", "Subcategory2-4"
],
},
getSubcategories: function () {
return this.subcategories;
}
});

我已经设法以这种方式成功地将变量发送到 SomethingController.js(仅复制了下面必要代码的一部分(：

define(
	[
"underscore",
"base/Controller",
"views/SomethingView",
"collections/SomethingCollection",
"helpers/Subcategories",
	], 
	function(_, Controller, SomethingView, SomethingCollection, Subcategories) {
		var subcategory = null,
		
		var SomethingController = Controller.extend({
			show_results: function(collection, resp) {
				var data = { 
					subcategories: Subcategories.getSubcategories(),
				};
...

但是当我尝试在 SomethingView.js 中导入变量时，它仅在我再次使用整个 json 对象时才有效：

define(
	[
		"jquery",
		"backbone",
		"has/form",
		"has!input-attr-placeholder?:jqueryui/placeholder",
		"scripts/libs/jquery.tmpl.js",
		"helpers/Subcategories",
	], 
	function( $, Backbone, viewTemplate, has, Subcategories) {
		
		var SomethingItemsView = Backbone.View.extend({
			el: $("#main-section"),
			template: viewTemplate,
			events: {
				"click #some_button" : "change_some_page",
			},
			something_items: function( event ) {
				event.preventDefault();
				var somethingCategory = $("#some_selector");
				var subcategories = {// entire json object
}
var somethingSubcategory =  subcategories[somethingCategory];
...

我试过var subcategories = Subcategories.getSubcategories()，Subcategories.subcategories和各种各样的东西。为这么小的事情浪费了相当多的时间。我很困惑为什么它不起作用，我不想在那里硬编码整个对象。

我正在对现有网站的前端进行一些更改，因此请注意，我无法更改任何这些文件的框架，除了子类别.js。

任何意见将不胜感激。

我认为您的问题来自依赖项的顺序：

[
"jquery",
"backbone",
"has/form",
"has!input-attr-placeholder?:jqueryui/placeholder",
"scripts/libs/jquery.tmpl.js",
"helpers/Subcategories",
], 
function( $, Backbone, viewTemplate, has, Subcategories) {

它必须按相同的顺序排列。子类别是第六个也是最后一个参数，但您只有五个输入。

jquery => $
backbone => Backbone
has/form => viewTemplate
has!... => has
scripts/libs/jquery.tmpl.js => Subcategories
helpers/Subcategories => OUPS NOTHING O_O
