如何将文件加载到html5音频标记中

<input type="file" id="file"></input>
<script>
var file = document.getElementById("file");
var audio = document.createElement("audio");
audio.src = file.value;
document.write(audio)
</script>

我相信它会满足您的需求.首先,文件输入需要通过JavaScript或jQuery绑定(如果您愿意).您可以使用 Blob browser support

以下是一个非常基本的例子;

<input type="file" id="file"></input>
<audio id="audio" controls autoplay></audio>

我们使用AddEventListener绑定#file以进行更改,如下所示

// check for BlobURL support
var blob = window.URL || window.webkitURL;
    if (!blob) {
        console.log('Your browser does not support Blob URLs :(');
        return;           
    }

document.getElementById('file').addEventListener('change',function(event){

        consolePrint('change on input#file triggered');
        var file = this.files[0],fileURL = blob.createObjectURL(filE);
        console.log(filE);
        console.log('File name: '+file.Name);
        console.log('File type: '+file.typE);
        console.log('File BlobURL: '+ fileURL);
        document.getElementById('audio').src = fileURL;

});

或者另一方面,这是我创建的nice and more interactive example
