Using local file as <audio> src

问题

Is it possible to use an audio file from the user's hard drive as the src attribute for an HTML5 <audio> tag? Maybe through an <input type="file" />? This might not be particularly useful in production, but I'm still curious if it can be done.

回答1:

I can think of two ways.

Within your audio tag:

src="file:///C:/.../file.mp3"

or you could use a Blob using the file API.

HTML:

<input type="file"></input>

JS:

audio.src = URL.createObjectURL(document.getElementsByTagName('input')[0].files[0]);
