HTML5 audio.volume的规格是什么

Question

I've seem some code indicating that with javascript you can set the volume level of an HTML5 <audio> element using something like document.getElementById('player').volume-=0.1 , but I can't find anything to indicate what the volume range is? 0-5? 0-10? 0-100? Does anyone know what the max volume of an audio tag is, and what the smallest increments it can be raised in are?

Answer 1

From the w3c HTML5 specification

... 4. Let volume be the playback volume of the audio portions of the media element, in range 0.0 (silent) to 1.0 (loudest).
