Angular JS 动态 ng-src 在 1.2.0-rc.2 中不起作用 [英] Angular JS dynamic ng-src not working in 1.2.0-rc.2
问题描述
我正在尝试在 Angular JS 应用程序中实现一个视频元素，而 ng-src 不会读取范围变量
I'm trying to implement a video element in an angular JS app and the ng-src won't read the scope variable
我使用的是 1.2.0-rc.2
I'm using 1.2.0-rc.2
<!DOCTYPE html>
<html ng-app="ngView">
<head>
<script src="http://code.angularjs.org/1.2.0-rc.2/angular.min.js"></script>
<script>
var app = angular.module('ngView', []);
function MyControl($scope){
$scope.file = '1234.mp4';
}
</script>
</head>
<body ng-controller="MyControl">
<video controls ng-src="http://www.thebigdot.com/{{file}}"></video>
</body>
</html>
如果我使用旧版本的 AngularJS 库，它可以工作.
If I use a much older version AngularJS lib, it works.
cdnjs.cloudflare.com/ajax/libs/angular.js/1.0.3/angular.min.js (works)
这是最新版本中的错误还是故意禁用的?有什么解决办法?
Is this a bug in the latest release or has it been disabled on purpose? What is the work around ?
推荐答案
经过一番调试我发现错误是这样的:
after a bit of debugging I found that the error is this:
<代码>错误:[$interpolate:noconcat] 插值时出错:http://www.thebigdot.com/{{file}}严格上下文转义不允许在需要可信值时连接多个表达式的插值.参见 http://docs.angularjs.org/api/ng.$sce
Error: [$interpolate:noconcat] Error while interpolating: http://www.thebigdot.com/{{file}}
Strict Contextual Escaping disallows interpolations that concatenate multiple expressions when a trusted value is required. See http://docs.angularjs.org/api/ng.$sce
