Question

我有一个用于产品的循环，效果很好。

<div ng-repeat="result in results track by result.uid">
      <img ng-src="{{ result.img';" alt="{{ result.name }}"
           title="{{ result.name }}" />
      <p><span class="money">&pound;{{ result.price | number:2 }}</span></p>
      <p class="product-title">
        <a ng-href="{{ result.url }}">{{ result.name }}</a>
      </p>
</div>

在循环中，有一个具有JSON数据的对象。

{{result.colours}}

其中包含以下内容：

    [
        {
            "id":866337128495,
            "title":"Product Title",
            "handle":"product-url",
            "image":"/img.jpg",
            "sku":"SKU001",
            "name":"Product Name",
            "type":"one_color",
            "data":"#000000"
        },
        {
            "id":866337128496,
            "title":"Product Title2",
            "handle":"product-url2",
            "image":"/img2.jpg",
            "sku":"SKU002",
            "name":"Product Name 2",
            "type":"one_color",
            "data":"#000000"
        }
]

我需要遍历这个，并尝试过：

<div ng-init="swatches=result.colours">
          <div ng-if="swatches">
                    <div ng-repeat="(key,value) in swatches">
                              {{key}}:{{value}}
                    </div>
           </div>
</div>

这只是返回：

    0: [
        {
            "id":866337128495,
            "title":"Product Title",
            "handle":"product-url",
            "image":"/img.jpg",
            "sku":"SKU001",
            "name":"Product Name",
            "type":"one_color",
            "data":"#000000"
        },
        {
            "id":866337128496,
            "title":"Product Title2",
            "handle":"product-url2",
            "image":"/img2.jpg",
            "sku":"SKU002",
            "name":"Product Name 2",
            "type":"one_color",
            "data":"#000000"
        }
]

我是Angular的新手，但是我研究了很多实现此功能的可能性，但都没有做到。任何想法都将受到欢迎！

Here is a link on how default parameters work in javascript

您快到了：

<div ng-if="swatches">
                <div ng-repeat="data in swatches">
                          <div ng-repeat="(key,value) in data">
                            {{key}}:{{value}}
                          </div>
                          <hr>
                </div>

angular.module("app", [])

  .run(function($rootScope) {

    $rootScope.results = [

      {
        name: "Demo",
        colors: [{
            "id": 866337128495,
            "title": "Product Title",
            "handle": "product-url",

            "data": "#000000"
          },
          {
