我可以使用 Angular 变量作为音频标签的来源吗? [英] Can I use Angular variables as the source of an audio tag?

问题描述

我正在尝试执行以下操作:

<audio ng-src="/data/media/{{audio}}" 控件></audio>

但是当我加载视图时，{{audio}} 变量没有被解析，而是按原样硬编码到源中.但是，例如，如果我将相同的变量放在音频标签之外，它会正确呈现音频文件的名称.我试过同时使用 src 和 ng-src 都无济于事.

有没有办法让变量在音频标签内工作?

提前致谢.

解决方案

好的，感谢 theJoeBiz 的输入和一些思考，我通过制定指令解决了这个问题，代码如下:

app.directive('audios', function($sce) {返回 {限制:'A'，范围:{代码:'='}，替换:真的，模板:'<audio ng-src="{{url}}" 控件></audio>',链接:功能(范围){scope.$watch('code', function (newVal, oldVal) {如果 (newVal !== 未定义) {scope.url = $sce.trustAsResourceUrl("/data/media/" + newVal);}});}};});

然后在模板上我像这样使用它:

<div 音频代码="音频"></div>

现在一切正常.

I am trying to do the following:

<div ng-repeat="audio in event.audios">
    <audio ng-src="/data/media/{{audio}}" controls></audio>
</div>

But when I load the view, the {{audio}} variable is not parsed but hardcoded into the source as is. However, if for example, I place that same variable outside of the audio tag it renders the name of the audio file correctly. I've tried using both src and ng-src to no avail.

Is there a way to get the variable to work within an audio tag?

Thanks in advance.

解决方案

Ok, thanks to theJoeBiz's input and some thinking around I solved this by making a directive, here is the code:

app.directive('audios', function($sce) {
  return {
    restrict: 'A',
    scope: { code:'=' },
    replace: true,
    template: '<audio ng-src="{{url}}" controls></audio>',
    link: function (scope) {
        scope.$watch('code', function (newVal, oldVal) {
           if (newVal !== undefined) {
               scope.url = $sce.trustAsResourceUrl("/data/media/" + newVal);
           }
        });
    }
  };
});

Then on the template I used it like so:

<div ng-repeat="audio in event.audios">
    <div audios code="audio"></div>
</div>

It is all working fine now.
