- 直接通过audio标签播放音乐已经在主流浏览器中不被允许,如下方所示(无论火狐浏览器还是谷歌浏览器中都会报错):
- 但是我们仍可以通过AudioContext的方式在大部分浏览器中播放音乐,代码如下:
window.AudioContext = window.AudioContext || window.webkitAudioContext || window.mozAudioContext || window.msAudioContext;
try {
var context = new window.AudioContext();;
var source = null;
var audioBuffer = null;
function stopSound() {
if (source) {
source.stop(0); //立即停止
}
}
function playSound() {
source = context.createBufferSource();
source.buffer = audioBuffer;
source.loop = true; //循环播放
source.connect(context.destination);
source.start(0); //立即播放
}
function initSound(arrayBuffer) {
context.decodeAudioData(arrayBuffer, function(buffer) { //解码成功时的回调函数
audioBuffer = buffer;
playSound();
}, function(e) { //解码出错时的回调函数
console.log(\'Error decoding file\', e);
});
}
function loadAudioFile(url) {
var xhr = new XMLHttpRequest(); //通过XHR下载音频文件
xhr.open(\'GET\', url, true);
xhr.responseType = \'arraybuffer\';
xhr.onload = function(e) { //下载完成
initSound(this.response);
};
xhr.send();
}
loadAudioFile(\'../Content/public/mp3/music2.mp3\');
$("#stop").click(function() {
stopSound();
});
} catch (e) {
console.log(\'!Your browser does not support AudioContext\');
}
- 效果如下(火狐浏览器中可以直接播放出声音来;至少现在在谷歌浏览器中不报错了):
