我的问题:
我想使用 ng-repeat 指令显示存储在本地的图像列表，但图像没有显示。
AngularJS 版本:1.2.22
代码:
目录结构:
myapp/ |--- common/ | |--- images/ | |--- image.png | |--- subapp1/ | |--- index.html | |--- subapp1.js | | | |--- controllers/ | | |--- SubApp1Controller.js | | | |--- views/ | | |--- imageListView.html
index.html
<!DOCTYPE html>
<html lang="en" data-ng-app="SubApp1">
<head>
<meta charset="utf-8" />
</head>
<body>
<div id="page" data-ng-view="">
</div>
<!-- Include required libs, models and controllers -->
<script type="text/javascript" src="../common/libs/angular.min.js"></script>
<script type="text/javascript" src="../common/libs/angular-route.min.js"></script>
<script type="text/javascript" src="../common/libs/angular-touch.min.js"></script>
<!-- Controllers -->
<script type="text/javascript" src="controllers/SubApp1Controller.js"></script>
<!-- App Module (main) -->
<script type="text/javascript" src="subapp1.js"></script>
</body>
</html>
- 子应用1.js
// Instantiate the SubApp1 Module.
var subApp1 = angular.module("SubApp1", ["ngRoute", "ngTouch"]);
// Setting Controllers
subApp1.controller("SubApp1Controller",
["$scope", SubApp1Controller]
);
// Define the routes for the module.
subApp1.config(function ($routeProvider) {
$routeProvider.when("/home", {
controller: "SubApp1Controller",
templateUrl: "views/imageListView.html"
});
$routeProvider.otherwise({redirectTo: "/home"});
});
- SubApp1Controller.js
function SubApp1Controller($scope)
{
/**
* Private Method: _run()
* The main function of the SubApp1Controller, where all the magic
* happens.
*/
function _run() {
// this variable will define which style will be loaded on the image list view
$scope.section = "subapp1";
var imageSource;
imageSource = "../common/images/image.png";
// list of media elements to be displayed on the list
$scope.mediaList = [
{
thumbnailPath: imageSource,
imagePath: imageSource,
},
{
thumbnailPath: imageSource,
imagePath: imageSource,
},
{
thumbnailPath: imageSource,
imagePath: imageSource,
},
{
thumbnailPath: imageSource,
imagePath: imageSource,
},
{
thumbnailPath: imageSource,
imagePath: imageSource,
},
];
};
// Runs the main method of this class
_run();
}
- imageListView.html
<div class="grid-background"></div>
<header class="grid-header {{section}}">
<div class="button-right"></div>
</header>
<ul id="grid" class="grid">
<li class="grid-item" data-ng-repeat="media in mediaList">
<img data-ng-src="{{media.thumbnailPath}}" data-src="{{media.imagePath}}"/>
</li>
</ul>
额外信息:
图像未加载，控制台中未打印任何错误消息。
我打开 Web Inspector 工具查看 li 元素中处理了什么，它没有 src 属性，如下所示:
<li class="grid-item ng-scope" data-ng-repeat="media in mediaList">
<img data-ng-src="../common/images/image.png" data-src="../common/images/image.png" />
</li>
如果我在 img 元素中添加 src 属性，它会被加载，但我会收到错误消息，请参见以下内容:
<li class="grid-item" data-ng-repeat="media in mediaList">
<img data-ng-src="{{media.thumbnailPath}}"
data-src="{{media.imagePath}}"
src="{{media.thumbnailPath}}"
/>
</li>
<!-- Error message printed in the console -->
GET file:///[ABS_PATH]/%7B%7Bmedia.thumbnailPath%7D%7D net::ERR_FILE_NOT_FOUND
我已经阅读了很多关于类似问题的帖子和问题/答案，但没有一个对我有用。有人知道吗？
提前致谢。
最佳答案
对于 IMG 标签和 AngularJS，只使用 ng-src 属性。
<img ng-src="{{media.imagePath}}" />
{{media.imagePath}} 必须包含图像的绝对或相对 URL。
