select 加上选项下拉列表播放音频文件

Question

我想使用 select 加选项下拉列表来播放音频文件。我想避免使用提交按钮而只使用 javascript onmouseup。下面的代码应该有效，但只显示下拉列表和音频控件。有人可以帮忙吗？

<form onsubmit="return false;">

<select id="audio_select">
<option value="Happy_Birthday">Song #1</option>
<option value="My_Way">Song #2</option>
<option value="Satisfaction">Song #3</option>
</select> 
<button onmouseover="submitted_audio()">Submit</button>
</form>

<script>
function submitted_audio(){
link = document.getElementById("audio_select").value;
document.getElementById("audio_player").src = "audio/"+link+".ogg";
}
</script>

<audio controls><source id = "audio_player" type = "audio/ogg"></audio>

Answer 1

您需要加载音频

<form onsubmit="return false;">

<select id="audio_select">
<option value="Happy_Birthday">Song #1</option>
<option value="My_Way">Song #2</option>
<option value="Satisfaction">Song #3</option>
</select> 
<button onmouseover="submitted_audio()">Submit</button>
</form>

<script>
function submitted_audio(){
link = document.getElementById("audio_select").value;
document.getElementById("audio_player").src = "audio/"+link+".ogg";
document.getElementById("audio").load();
}
</script>

<audio id="audio" controls><source id = "audio_player" type = "audio/ogg"></audio>
