我试图让浏览器显示警报,如果音频元素src属性指向不存在的文件,但是如果我附加"错误"事件,我不会得到任何响应.

这是我的问题和我尝试过的问题http://jsfiddle.net/Xx2PW/7/

HTML:

<p>Non existent audio files - should return an error
    <audio preload="auto">
        <source src="http://example.com/non-existant.wav" />
        <source src="http://example.com/non-existant.mp3" />
        <source src="http://example.com/non-existant.ogg" />
    </audio>
</p>
<p>Existing audio file - should just play
    <audio preload="auto">
        <source src="http://jplayer.org/audio/m4a/Miaow-07-Bubble.m4a" />
    </audio>
</p>

和JS:

playerMarkup = "<a class=\"player\">Play</a>";
audioTags = $("audio");

audioTags.before(playerMarkup); //insert markup before each audio tag

$(".player").on("click", function () {
    currentAudio = $(this).next()[0];
    //I've tried catching the error like this - no effect
    alert("Trying to play file.");
    try {
        currentAudio.play();
    } …
