AngularJS和Typeahead：根据选定的值访问数组中的数组(AngularJS and Typeahead : Accessing an array within an array based on a selected value)

我是AngularJS领域的新成员，希望能帮助您找到答案：在我的控制器中，我有以下列表/对象：

$scope.languageModel = { brands: [{ id: 1, name: 'ALGS' }, { id: 2, name: 'BLVT' }], commodities: [ { id: 1, name: 'Apples', varieties: [{ id: 1, name: 'GS' }, { id: 2, name: 'GX' }], sizes: [{ id: 1, name: 'S' }, { id: 2, name: 'M' }], qualities: [{ id: 1, name: 'LQ' }, { id: 2, name: 'GQ' }] }, { id: 2, name: 'Oranges', varieties: [{ id: 1, name: 'OR' }, { id: 2, name: 'ZO' }], sizes: [{ id: 1, name: 'S' }, { id: 2, name: 'M' }], qualities: [{ id: 1, name: 'LQ' }, { id: 2, name: 'GQ' }] } ] }

languageModel充当数据填充到的对象：

这些当然位于桌子上。上面提到的所有代码都是我目前拥有的代码。我想知道的是如何确保#variety（同样适用于#size）由选定的#commodity填充。

例如，如果我选择苹果作为我的＃商品，那么＃variety的列由苹果商品列表中的品种填充。

#brands和#commodity填充正常并且按照他们应该的方式工作，但是getAttributeType（）似乎不起作用，并且当我运行应用程序时，#commodity上的下面的框基本上被视为普通文本框。

I am new in the area concerning AngularJS and would like help figuring this out: In my controller I have the following list/object:

$scope.languageModel = { brands: [{ id: 1, name: 'ALGS' }, { id: 2, name: 'BLVT' }], commodities: [ { id: 1, name: 'Apples', varieties: [{ id: 1, name: 'GS' }, { id: 2, name: 'GX' }], sizes: [{ id: 1, name: 'S' }, { id: 2, name: 'M' }], qualities: [{ id: 1, name: 'LQ' }, { id: 2, name: 'GQ' }] }, { id: 2, name: 'Oranges', varieties: [{ id: 1, name: 'OR' }, { id: 2, name: 'ZO' }], sizes: [{ id: 1, name: 'S' }, { id: 2, name: 'M' }], qualities: [{ id: 1, name: 'LQ' }, { id: 2, name: 'GQ' }] } ] }

The languageModel serve as the object from which data is populate into:

These are of course located in a table. All the above mentioned code is what I currently have. What I would like to know is how to ensure that #variety (same goes for #size) is populated by the #commodity selected.

For example if I had selected Apples as my #commodity then the column for #variety is populated by the varieties in the list of the Apples commodity.

The #brands and #commodity populate fine and work as they should, however getAttributeType() doesn't seem to work and when I run the app the boxes following on #commodity is basically treated as normal textboxes.
