Question

我有一个html的音频文件。我想要4个按钮：一个用于播放，一个用于暂停，一个用于停止，一个用于30秒跳过。暂停/播放工作。另外2人不要。我花了2个小时尝试通过互联网搜索，我根本无法理解。这是我的代码。

<script>
function playsong() {
    document.getElementById("Player").play();
}

function pausesong() {
    document.getElementById("Player").pause();
}

function stopsong() {
    document.getElementById('Player').setcurrentTime();/**tried also with audio.currentTime here. Didn't worked **/
    audio.currentTime = 0;
}

function forwardAudio() {
    document.getElementById('Player').setcurrentTime(); /**tried also with audio.currentTime here. Didn't worked **/
    audio.currentTime += 30.0

}
</script>

    </audio>
    <button type="button" onclick="playsong()">Play</button>
    <button type="button" onclick="pausesong()">Pauza</button>
    <button type="button" onclick="stopsong()">Stop</button>
    <button type="button" onclick="forwardAudio()">Skip 30 seconds</button>
</body>

Answer 1

您没有音频变量。您需要抓住播放器并直接对播放器进行更改。你还需要在stopsong（）上暂停（），否则它将返回到开头但继续播放。

function stopsong() {
    var player = document.getElementById('Player');
    player.pause();
    player.currentTime = 0;/**tried also with audio.currentTime here. Didn't worked **/
}

function forwardAudio() {
    var player = document.getElementById('Player');
    player.currentTime += 30.0; /**tried also with audio.currentTime here. Didn't worked **/

}

我希望在HTML中停止/跳过音频30秒
