如何仅在触发播放按钮时让音乐自动播放？

Question

我正在尝试在我的网站上实现一个音频栏，它会从歌曲列表中随机选择要播放的歌曲。音乐应该开始，但只有在按下播放按钮时才开始，当一首歌曲结束时，自动播放下一首歌曲。下面的代码工作正常，除了前面提到的，音乐在没有按下播放按钮的情况下自行播放。有谁知道如何解决这个问题？我尝试设置player.autoplay=true;为，false但下一首歌曲不会自动播放。<audio id="audioplayer" controls> <!-- Remove the "Controls" Attribute if you don't want the visual controls --></audio><script>    var lastSong = null;    var selection = null;    var playlist = ["sounds/0.mp3", "sounds/1.mp3", "sounds/2.mp3"]; // List of Songs    var player = document.getElementById("audioplayer"); // Get Audio Element    player.autoplay=true;    player.addEventListener("ended", selectRandom); // Run function when song ends    function selectRandom(){        while(selection == lastSong){ // Repeat until different song is selected            selection = Math.floor(Math.random() * playlist.length);        }        lastSong = selection; // Remember last song        player.src = playlist[selection]; // Tell HTML the location of the new Song    }    selectRandom(); // Select initial song    player.play(); // Start Song</script>

Answer 1

你有没有试过删除 player.play();

Answer 2

创建一个按钮并添加一个onclick属性，移动selectRandom() 到一个按钮onclick函数，如下所示：

var player = document.getElementById("audioplayer");

var lastSong = null;

var selection = null;

var playlist = ["https://www.soundjay.com/button/sounds/beep-07.mp3", "https://www.soundjay.com/button/sounds/button-2.mp3", "https://www.soundjay.com/button/sounds/button-3.mp3"]; // List of Songs

function start() {

   player.play();

   player.addEventListener("ended", selectRandom);

   

    function selectRandom(){

        while(selection == lastSong){ // Repeat until different song is selected

            selection = Math.floor(Math.random() * playlist.length);

        }

        lastSong = selection; // Remember last song

        player.src = playlist[selection]; // Tell HTML the location of the new Song

    }

    player.autoplay=true;

    selectRandom();

}

<audio id="audioplayer" controls ></audio>

<button onclick="start()"> Play </button>
