带有js和/或angularjs的JSON @attributes和@association级别

Question

我目前正在开发一个使用API​​来检索,更新和删除数据的项目.我正在使用的API是prestashop API.因此,在能够检索数据并更新某些项目之后,我偶然发现了一个问题.正如文档中所述,通过API发送和检索的所有数据都是json和.xml由于API的某些数据在json返回中具有不同的级别,如@attributes和@associations级别,我提出了这个问题.

问题是我想访问这些数据,并结合angularjs我想显示这些数据.所以,让我向您展示一个我正在努力实现的快速示例.

首先,JSON回报将是这样的.

{"products":{"product":[{"id":"1","id_manufacturer":"1","id_supplier":"1","id_category_default":"5","new":{},"cache_default_attribute":"1","id_default_image":"1","id_default_combination":"1","id_tax_rules_group":"1","position_in_category":"0","manufacturer_name":"Fashion Manufacturer","quantity":"0","type":"simple","id_shop_default":"1","reference":"demo_1","supplier_reference":{},"location":{},"width":"0.000000","height":"0.000000","depth":"0.000000","weight":"0.000000","quantity_discount":"0","ean13":"333456789111","isbn":{},"upc":{},"cache_is_pack":"0","cache_has_attachments":"0","is_virtual":"0","state":"1","on_sale":"0","online_only":"0","ecotax":"0.000000","minimal_quantity":"1","price":"16.510000","wholesale_price":"4.950000","unity":{},"unit_price_ratio":"0.000000","additional_shipping_cost":"0.00","customizable":"0","text_fields":"0","uploadable_files":"0","active":"1","redirect_type":"404","id_type_redirected":"0","available_for_order":"1","available_date":"0000-00-00","show_condition":"0","condition":"new","show_price":"1","indexed":"1","visibility":"both","advanced_stock_management":"0","date_add":"2017-03-16 14:36:24","date_upd":"2017-12-01 13:01:13","pack_stock_type":"3","meta_description":{"language":{"@attributes":{"id":"1"}}},"meta_keywords":{"language":{"@attributes":{"id":"1"}}},"meta_title":{"language":{"@attributes":{"id":"1"}}},"link_rewrite":{"language":"gebleekte-T-shirts-met-korte-mouwen"},"name":{"language":"Gebleekte T-shirts met Korte Mouwen"},"description":{"language":"

Het resultaat? Cool, gemakkelijk, easy, chique met jeugdige elegantie en een duidelijk herkenbare stijl. Alle prachtige kledingstukken worden met de grootste zorg gemaakt in Itali\u00eb.

结构简化了

products {
product {
        id:
        name:
        category:
        ...
        @attributes {
            id:
            language:
            ...
        }
        @attributes {
            {"nodeType":"product_option_value","api":"product_option_values"},"product_option_value":[
                {"id":"1"},
                {"id":"11"},
                {"id":"8"}, 
                {"id":"2"},
                {"id":"3"}
                ]
            },
        }
    }
}

使用$http.get()Angularjs中的函数我能够检索数据并使用ng-repeat和bind组合来显示product_names.现在我想访问@attribute值,依此类推.但是我怎么能够访问它们？有没有具体的方法来做到这一点？或者它是纯粹通过访问JSON对象的深度级别来完成的？

产品的AngularJS功能:

$http.get('config/get/getProducts.php', {cache: true}).then(function (response) {
        $scope.products = response.data.products.product
    });

然后在<html>我可以简单地使用:

<div ng-if="product.active == 1" class="productimg col-4" ng-repeat="product in products | filter : {id_category_default: catFilter.id}: true | filter:productSearch | filter:product.name | orderBy: 'name'">
    <p ng-bind="product.name.language"></p>
</div>

更新:01/02/2018 因此,在阅读并测试了一些评论后,我提出了一个合理的解决方案.我能够访问@attributes和association值,但我偶然发现了一个新问题.我为每个过滤器获得的回报是多个"id"值.看看下面的例子.

<div class="col-lg-3" ng-repeat="value in products">
    <p ng-bind="value.associations.categories.category"></p>
</div>

返回:

[{"id":"2"},{"id":"3"},{"id":"4"},{"id":"5"}]

[{"id":"2"},{"id":"3"},{"id":"4"},{"id":"5"}]

[{"id":"2"},{"id":"3"},{"id":"4"},{"id":"7"}]

每一行[.. ..]代表不同的产品.现在我需要将这些值仅作为它们的数字,以便我可以将它们与来自不同表的相应id值进行比较.一个好结果将是:

2, 3, 4, 5

问题是我如何才能获得这个解决方案？

如果有人对原因和方式感兴趣.我正在尝试从prestashop安装中的产品中检索option_valuesid和categoryid,以及通过prestashop webservice获取的所有内容.

Answer 1

据我了解,您希望将ng-repeat与嵌套的JSON对象一起使用.您将需要使用多个转发器,因为一个重复的项目可以包含您想要显示的多个项目.

所以我可以看到这样的东西应该工作:

<div ng-if="product.active == 1" class="productimg col-4" ng-repeat="product in products | filter : {id_category_default: catFilter.id}: true | filter:productSearch | filter:product.name | orderBy: 'name'">
    <p ng-bind="product.name.language"></p>
    <table ng-repeat="cat in product.associations.categories">
        <tr ng-repeat="attr in cat.@attributes">
            <td >{{attr.nodeType}}</td>
            <td >{{attr.api}}</td>
        </tr>
    </table>
</div>

Answer 2

我认为您唯一的问题是使用点符号来访问@attributes product.associations.categories.@attributes

这不是有效的javascript,因此您应该对此属性使用括号表示法.

像这样: product.associations.categories['@attributes']

Answer 3

从你的问题我明白问题是访问@attribute里面的属性ng-repeat,请在下面找到一个显示@attribute值的示例使用ng-repeat我们也可以使用bracket notation而不是访问对象属性dot notation,在这里阅读更多.

如果这个答案有助于解决您的问题,或者我在答案中遗漏了什么,请告诉我.
