连续Html5音频.play()只有第一次触发

标签: javascript jquery html ipad html5-audio

我希望通过在每个函数中使用.play()执行函数调用回退来播放连续的声音序列,以便逐个播放声音。

最有趣的是: 每次在iPad设备上播放时都会有不同的声音表现。 * 有时播放音频3次,有时4次,甚至只播放1次! *

仅限iPad上的“突然停止问题”,我的Google Chrome浏览器就可以了。

这不是iPad的自动播放问题我猜是因为我已经在第一时间触发......

请查看并在iPad上进行测试,请帮助......

Html - 正文:

<audio id="html5soundtag"> 
    <source src="1.mp3" type="audio/mpeg">
</audio> 
<a href="javascript://" onClick="playhtml5sound1('1.mp3')">aaaa</a> 

使用Javascript:

var audioPath ="";

var audioElement = document.getElementById('html5soundtag');

function playhtml5sound1(filename){ 
    audioPath = filename;
    audioElement.src = audioPath;
    audioElement.src = audioPath
    audioElement.load()
    audioElement.play();
    audioElement.addEventListener("ended",soundcallback1);
};
var soundcallback1 = function (){
    alert("1st");
    audioElement.removeEventListener("ended",soundcallback1);
    playhtml5sound2("1.mp3");
}


function playhtml5sound2(filename){
    audioPath = filename;
    audioElement.src = audioPath;
    audioElement.src = audioPath
    audioElement.load();        
    audioElement.play();
    audioElement.addEventListener("ended",soundcallback2);

};
var soundcallback2 = function (){
    alert("2nd");
    audioElement.removeEventListener("ended",soundcallback2);
    playhtml5sound3("1.mp3");
}

function playhtml5sound3(filename){
    audioPath = filename;
    audioElement.src = audioPath;
    audioElement.src = audioPath
    audioElement.load();
    audioElement.play();
    audioElement.addEventListener("ended",soundcallback3);

};var soundcallback3 = function (){
    alert("3rd");
    audioElement.removeEventListener("ended",soundcallback3);
    playhtml5sound4("1.mp3");
}

function playhtml5sound4(filename){
    audioPath = filename;
    audioElement.src = audioPath;
    audioElement.src = audioPath
    audioElement.load();
    audioElement.play();

    audioElement.addEventListener("ended",soundcallback4);

};var soundcallback4 = function (){
    alert("4th");
    audioElement.removeEventListener("ended",soundcallback4);
    playhtml5sound5("1.mp3");
}

function playhtml5sound5(filename){
    audioPath = filename;
    audioElement.src = audioPath;
    audioElement.src = audioPath
    audioElement.load();
    audioElement.play();

    audioElement.addEventListener("ended",soundcallback5);

};var soundcallback5 = function (){
    alert("5th");
    audioElement.removeEventListener("ended",soundcallback5);
    playhtml5sound6("1.mp3");
}

function playhtml5sound6(filename){
    alert("This is End. " + filename);
}

这应该可以解决您的问题,至少可以使您的代码更易于维护:

var audioPath = "";
var audioElement = document.getElementById('html5soundtag');

var soundIndex = 0;
var sounds = ["1.mp3","2.mp3","3.mp3","4.mp3","5.mp3"]

function playhtml5sound(){
    if(soundIndex < sounds.length){
        audioPath = sounds[soundIndex];
        audioElement.src = audioPath;
        audioElement.load()
        audioElement.play();
        soundIndex++;
    }else{
        audioElement.removeEventListener("ended",playhtml5sound);
        alert("Last sound ended!")
    }
};

audioElement.addEventListener("ended", playhtml5sound);
<a href="javascript://" onClick="playhtml5sound()">aaaa</a> 

每次音乐结束时,都会执行playhtml5sound(),播放下一个声音 如果播放了最后一个声音,请删除事件侦听器,并提示结束。

不是直接答案,但代码太大,无法在评论中显示。

我建议您将以下代码添加到脚本中,并检查控制台日志中是否有除结束之外的任何其他事件(例如停顿或错误事件)。我在iPad和iPod上测试过,两者都运行正常,也许你因网络问题而出错。

var media_events = new Array();
function audioattachevents(selector) {
    media_events["abort"] = 0;
    media_events["error"] = 0;
    media_events["mousewheel"] = 0;
    media_events["blur"] = 0;
    media_events["focus"] = 0;
    media_events["pause"] = 0;
    media_events["canplay"] = 0;
    media_events["formchange"] = 0;
    media_events["play"] = 0;
    media_events["canplaythrough"] = 0;
    media_events["forminput"] = 0;
    media_events["playing"] = 0;
    media_events["change"] = 0;
    media_events["input"] = 0;
    media_events["progress"] = 0;
    media_events["click"] = 0;
    media_events["invalid"] = 0;
    media_events["ratechange"] = 0;
    media_events["contextmenu"] = 0;
    media_events["keydown"] = 0;
    media_events["readystatechange"] = 0;
    media_events["dblclick"] = 0;
    media_events["keypress"] = 0;
    media_events["scroll"] = 0;
    media_events["drag"] = 0;
    media_events["keyup"] = 0;
    media_events["seeked"] = 0;
    media_events["dragend"] = 0;
    media_events["load*"] = 0;
    media_events["seeking"] = 0;
    media_events["dragenter"] = 0;
    media_events["loadeddata"] = 0;
    media_events["select"] = 0;
    media_events["dragleave"] = 0;
    media_events["loadedmetadata"] = 0;
    media_events["show"] = 0;
    media_events["dragover"] = 0;
    media_events["loadstart"] = 0;
    media_events["stalled"] = 0;
    media_events["dragstart"] = 0;
    media_events["mousedown"] = 0;
    media_events["submit"] = 0;
    media_events["drop"] = 0;
    media_events["mousemove"] = 0;
    media_events["suspend"] = 0;
    media_events["durationchange"] = 0;
    media_events["mouseout"] = 0;
    media_events["timeupdate"] = 0;
    media_events["emptied"] = 0;
    media_events["mouseover"] = 0;
    media_events["volumechange"] = 0;
    media_events["ended"] = 0;
    media_events["mouseup"] = 0;
    media_events["waiting"] = 0;

    for (key in media_events) {
      selector.bind(key, function (e, data) {
        console.log(e.type);
      });
    }
}

audioattachevents($('#html5soundtag'));

特别是那些想要简短符号的人:
