将 angular-ui 与 angular 一起使用。标记包括一个ng-scroll
元素,我使用它从服务中检索到的数据。我想ng-repeat
在ng-scroll
. 这原则上有效(plunker),但 AngularJS 说我在 JSON 编码中有问题,需要帮助找出我做错了什么。
需要明确的是,下面的标记和 JSON 在 plunker 中有效,但在应用程序中无效。plunker 和下面的 JSON 取自调试器响应正文。
标记:
<div class="row" >
<div class="col-md-12" >
<div class="video_thumb" ng-scroll='video_list in VideoIndexScrollerSource' buffer-size='10' padding="2" >
<div class="row" ng-repeat="video in video_list">
<p>
<a ng-href="/guides/{{video._id}}" target="_self">
<img ng-src="{{video.thumb}}">
</a>
</p>
</div>
</div>
</div>
</div>
JSON:
在 Rails 中,我创建了一个数组数组。每个元素都是在上面的显示代码中使用的属性的散列。返回的 JSON 如下所示:
[
[
{
"thumb": "/uploads/thumb_11167113_det.jpg",
"_id": "52264092a0eef2d029673f72"
},
{
"thumb": "/uploads/thumb_11169448_det.jpg",
"_id": "522649b7a0eea05c61388f4a"
},
{
"thumb": "/uploads/thumb_278817_det.jpg",
"_id": "522649b4a0eea05c61388be2"
},
{
"thumb": "/uploads/thumb__old_",
"_id": "522e5290e4b0889f651f13ae"
},
{
"thumb": "/uploads/thumb_269411_det.jpg",
"_id": "522649baa0eea05c613891b3"
},
{
"thumb": "/uploads/thumb__old_",
"_id": "5227d1f3a0ee91bdc636efb9"
},
{
"thumb": "/uploads/thumb_11169964_det.jpg",
"_id": "52264091a0eef2d029673e49"
}
],
[
...
],
[
...
]
]
不知道为什么这不起作用,ng-scroll 应该迭代将数组放入 video_list 的行,ng-repeat 应该从行中获取每个对象并获取值。
错误:
这是返回上述 JSON 时出现的 AngularJS 错误:
