取消选中复选框时，如何使用JavaScript关闭HTML5音频？

Question

I have the following javascript code to play some HTML5 sounds:

    var html5_audiotypes={ //define list of audio file extensions and their associated audio types. Add to it if your specified audio file isn't on this list:
        "mp3": "audio/mpeg",
        "mp4": "audio/mp4",
        "ogg": "audio/ogg",
        "wav": "audio/wav"
    }

    function createsound(sound){
        var html5audio=document.createElement('audio')
        if (html5audio.canPlayType){ //check support for HTML5 audio
            for (var i=0; i<arguments.length; i++){
                var sourceel=document.createElement('source')
                sourceel.setAttribute('src', arguments[i])
                if (arguments[i].match(/\.(\w+)$/i))
                    sourceel.setAttribute('type', html5_audiotypes[RegExp.$1])
                html5audio.appendChild(sourceel)
            }
            html5audio.load()
            html5audio.playclip=function(){
                html5audio.pause()
                html5audio.currentTime=0
                html5audio.play()
            }
            return html5audio
        }
        else{
            return {playclip:function(){throw new Error("Your browser doesn't support HTML5 audio")}}
        }
    }

//Initialize two sound clips with 1 fallback file each:
var sound1=createsound("audio/tileSelect.ogg", "audio/tileSelect.mp3")
var sound2=createsound("audio/tileRemove.ogg", "audio/tileRemove.mp3")

With sound1.playclip(); used in other functions I can play the sounds

The problem:

I have a checkbox with ID: sound . When checked, the sound should be heard, if not, no sound should be heard.

The code for the checkbox currently is:

function playSound() {
    if (document.getElementById('sound').checked){
        [something has to be added here?]
    }
}

What do I need to add in this part to hear the sound when checked and not when unchecked? I can't seem to get it working.

Kind regards, Maurice

Answer 1

Nevermind, I solved it. I was thinking too hard, it can be done very simple:

if (document.getElementById('sound').checked){
                sound1.playclip(); 
            }

This works
