AngularJS链接选择 [英] AngularJS chaining select

问题描述

我想实现一个链接的选择，但链都不能正常工作。

I'm trying to implement that chained select, but chains aren't working properly.

我想要什么，需要：如选择ALPARGATAS作为类别时，与选择的上市品牌，类别应仍处于选中状态为ALPARGATAS或选择时，卡尔文·克莱恩作为品牌，并选择任何列出的类别，品牌应该还是选择 Calvin Klein的。

What I want, need: e.g. when selecting 'alpargatas' as category, and with any listed brand selected, the category should be still selected as 'alpargatas' or when selecting 'Calvin Klein' as brand, and with any listed category selected, the brand should be still selected as 'Calvin Klein'.

推荐答案

您需要使用过滤器以正确的顺序。

You need to use filter in correct order.

有关类别下拉菜单

1. 按品牌如过滤器添加过滤器：{品牌：filterObject.brand}：//如此严格的方式传递true


2. 则唯一过滤像独特的：'类'


3. 和最后一个排序依据过滤像排序依据：'类'

1. add a filter by brand like filter:{brand: filterObject.brand}: true//pass true for strict mode
2. then the unique filter like unique: 'category'
3. and last the orderBy filter like orderBy:'category'

在 HTML ，它看起来像

<select ng-model="filterObject.category" 
        ng-options="c.category as c.category for c in shoes|filter:{brand: filterObject.brand}: true| unique: 'category'| orderBy:'category'">
<option value="" ng-value="undefined">-- Category:</option>

为品牌下拉菜单

<select ng-model="filterObject.brand" 
        ng-options="b.brand as b.brand for b in shoes|filter:{category: filterObject.category}: true| unique: 'brand'| orderBy:'brand'">
<option value="" ng-value="undefined">-- Brand:</option>

看这两个下拉菜单是绑定你的主数据源 $ scope.shoes ，所以你不需要在您的控制器额外的过滤器。

Look both dropdowns are bind with your main data source $scope.shoes so you don't need the additional filter in your controller.
