[HTML]網頁音效播放相容性整理

客戶要求千奇百怪，之前做的線上客服系統，希望收到訊息時加上音效提示，希望把它當作MSN(翻桌)，基本上這樣還蠻吵的，但在這吵雜聲中，順便把各種撥放音效的方式做個瀏覽器相容性的整理。

 

1.Hyperlink

IE7+(會跳出下載視窗)、Chome、Firefox、Opera

<a href="msg.wav">Play Sound</a>

 

2.embed

IE7、Chome、Firefox、Opera

<embed src="msg.wav" autostart="false" loop="false">

 

3.Javascirpt(舊方法)

IE7+、Chome、Firefox、Opera(除IE外，剛進入頁面的時候接會撥放一次)

<script>
    function PlaySound(soundobj) {
        var thissound = eval("document." + soundobj);
        thissound.Play();
    }
</script>
<input type="button" value="Play Sound" onClick="PlaySound('sound1')">
<embed src="msg.wav" autostart=false width=0 height=0 name="sound1" enablejavascript="true">

 

4.Javascript(新方法)

IE7+、Chome、Firefox、Opera(除IE外，剛進入頁面的時候接會撥放一次)

<script>
function EvalSound(soundobj) {
    var thissound = document.getElementById(soundobj);
    thissound.Play();
}
</script>

<embed src="msg.wav" autostart="false" width="1" height="1" id="sound1"
enablejavascript="true">
<input type="button" value="Play Sound" onClick="EvalSound('sound1')">

 

5.Background標籤

IE Only

<bgsound id="sound">
<script>
    function PlaySound(url) {
        document.all.sound.src = url;
    }
</script>
<input type="button" value="Play Sound" onClick="PlaySound('msg.wav')">

 

6.Dynamic HTML

IE7+、Chome、Firefox、Opera

<script>
function DHTMLSound(surl) {
    document.getElementById("dummyspan").innerHTML =
      "<embed src='" + surl + "' hidden=true autostart=true loop=false>";
}
</script>
<span id=dummyspan></span>
<input type="button" value="Play Sound" onClick="DHTMLSound('msg.wav')">

 

7.HTML5

IE9+(只支援mp3)、Chome、Firefox、Opera

<script>
    function EvalSound(soundobj) {
        var thissound = document.getElementById(soundobj);
        thissound.play();
    }
</script>
<audio id="audio1" src="msg.wav" controls preload="auto" autobuffer >
</audio>
<input type="button" value="Play Sound" onClick="EvalSound('audio1')">

 

結論

如果要再某個事件觸發(如Click)又要兼顧相容性，方法6是比較好的做法
