javascript - ng-src 无法正常工作

Question

我正在使用 Ionic Framework 1 和 AngularJS 构建移动应用

我有 REST 服务返回 JSON 数据。数据是一个相册，由名称和相册中的图像数组组成。我想使用嵌套的 ng-repeat 在 View 中显示相册及其照片。

我的系统信息:

$ ionic info

<!-- ng-repeat photo albums -->

        <a class="item item-list-detail">
            <ion-scroll direction="x">
              <img ng-repeat="image in album.images" ng-src="{{image.img-id}}" ng-click="showImages($index)" class="image-list-thumb">

JSON

{
    "albumName": "Business School 2016",

    "images": [{
            "img-id": 1,
            "img-src": "http://www.freedigitalphotos.net/images/img/homepage/87357.jpg"

        }
    ]
},

{
    "albumName": "Summer School 2016",

    "images": [{
            "img-id": 1,
            "img-src": "http://nehandaradio.com/wp-content/uploads/2016/07/Evan-Mawarire-outside-Harare-Magistrates-Court.jpg"
        },

        {
            "img-id": 2,
            "img-src": "http://resources0.news.com.au/images/2015/03/31/1227286/010588-3399e81e-d282-11e4-a5b4-b2d65ac8975a.jpg"

            "img-src": "http://nehandaradio.com/wp-content/uploads/2016/07/riot-police-at-mawarire-court-hearing.jpg"
        },

        {
            "img-id": 4,
            "img-src": "http://placehold.it/300x300"
        }
    ]
}

]

运行结果

So ng-repeat is correctly iterating over the 2 albums & 4 images in each but the images are not displaying, upon inspecting elements, ng-src="0"

因此 ng-repeat 正确地遍历了 2 个相册和每个相册中的 4 张图像，但是图像没有显示，在检查元素时，ng-src="0"。这是怎么回事？我该如何解决？

Answer 1

我认为应该是 ng-src="{{image['img-src']}}" 而不是 ng-src="{{image.img-id} }" 在你的 img 标签中。

您传递了错误的属性，并且由于属性名称中的连字符，您还需要使用方括号表示法。
