HTML5音频播放列表 - 如何在第一个音频文件结束后播放第二个音频文件？

Question

How could we make some audio in html5 play after another one has finished?

I have tried with jquery delay() function but it wont work at all, is it possible using pause() in html5 audio with timer instead ? For example, pause('500',function(){}); ?

Answer 1

Here's a JSLinted, unobtrusive Javascript example demonstrating how to handle and use the ended mediaevent . In your particular situation, you would trigger playback of the second audio file in your ended event handler.

You can use the code below or run the test fiddle .

Click an item in the playlist to begin playback. After one audio ends, the next will begin.

markup: (note the deliberate avoidance of whitespace between <li> elements - this is to simplify traversing the DOM with nextSibling .)

<audio id="player"></audio>

<ul id="playlist"><li data-ogg="http://www.lunerouge.org/sons/sf/LRWeird%201%20by%20Lionel%20Allorge.ogg">Space 1</li><li data-ogg="http://www.lunerouge.org/sons/sf/LRWeird%202%20by%20Lionel%20Allorge.ogg">Space 2</li><li data-ogg="http://www.lunerouge.org/sons/sf/LRWeird%203%20by%20Lionel%20Allorge.ogg">Space Lab</li></ul>

<button id="stop">Stop</button>

script:

// globals
var _player = document.getElementById("player"),
    _playlist = document.getElementById("playlist"),
    _stop = document.getElementById("stop");

// functions
function playlistItemClick(clickedElement) {
    var selected = _playlist.querySelector(".selected");
    if (selected) {
        selected.classList.remove("selected");
    }
    clickedElement.classList.add("selected");

    _player.src = clickedElement.getAttribute("data-ogg");
    _player.play();
}

function playNext() {
    var selected = _playlist.querySelector("li.selected");
    if (selected && selected.nextSibling) {
        playlistItemClick(selected.nextSibling);
    }
}

// event listeners
_stop.addEventListener("click", function () {
    _player.pause();
});
_player.addEventListener("ended", playNext);
_playlist.addEventListener("click", function (e) {
    if (e.target && e.target.nodeName === "LI") {
        playlistItemClick(e.target);
    }
});​

If this is your audio tag:

<audio id="player" src="someAudio.mp3"/>

then adding an event listener to it for the "ended" event will make it possible to change the source and play your next sound.

var audio = document.getElementById("player");
audio.addEventListener("ended", function() {
    audio.src = "nextAudio.mp3";
    audio.play();
});

I think this answer will help you ...

html5 audio player - jquery toggle click play/pause?

so instead of a click you should use a setTimeout, or a setInterval, which ever you feel more comfortable with to check constantly for the .paused==false I think you might be able to check if it is finished by checking videos's length and compare it with max length, which == end of file.
