javascript - Angular 不会更改 json 中的音频源

Question

我正在尝试使用音频标签将音频文件嵌入到 HTML 中。播放音频的src是从API获取的，我有5-6个不同的音频文件。

当我点击 playStart() 时，播放的音频文件是相同的，即使 src 显示不同的链接

<tbody>
    <tr ng-repeat="val in values track by $index">
        <td ng-bind="$index +1">1</td>
        <td ng-bind="val._id">ED1500322</td>
        <td>
            <audio id="audioTag">
                <source controls ng-src="{{val.file}}"></source>
            </audio>

            <button class="play-btn" ng-click="playStart()"><img src="app_static/images/play.png"></button>
            <button class="play-btn" ng-click="playStop()">stop</button>
        </td>
        <td ng-bind="val.result"></td>

    </tr>
</tbody>

JS文件

$scope.playStart = function() {
    var audio = document.getElementById("audioTag");
    audio.load();
    audio.play();

};

$scope.playStop = function() {
    var audio = document.getElementById("audioTag");
    audio.pause();
    audio.currentTime = 0;
};

即使 DOM 显示链接不同，我也只听到相同的音频剪辑

对于播放从 api 获得的音乐提供任何帮助，我们将不胜感激

使用类似的类:

HTML

<tbody>
<tr ng-repeat="val in values track by $index">
    <td ng-bind="$index +1">1</td>
    <td ng-bind="val._id">ED1500322</td>
    <td>
        <audio class="audioTag">
            <source controls ng-src="{{val.file}}"></source>
        </audio>

        <button class="play-btn" ng-click="playStart($index)"><img src="app_static/images/play.png"></button>
        <button class="play-btn" ng-click="playStop($index)">stop</button>
    </td>
    <td ng-bind="val.result"></td>

</tr>

JS

$scope.playStart = function(index_) {
    var audio = document.getElementsByClassName("audioTag")[index_];
    audio.load();
    audio.play();

};

$scope.playStop = function() {
    var audio = document.getElementsByClassName("audioTag")[index_];
    audio.pause();
    audio.currentTime = 0;
};
