我有以下的javascript代碼玩一些HTML5的聲音:如果在複選框未選中時如何使用javascript關閉HTML5音頻?
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")
隨着sound1.playclip();
在其他功能使用,我可以播放聲音
問題:
我有ID的複選框: sound
。選中時應該聽到聲音,否則聽不到聲音。
代碼爲複選框當前是:
function playSound() {
if (document.getElementById('sound').checked){
[something has to be added here?]
}
}
什麼,我需要在這部分增加檢查時,聽到的聲音,而不是選中的時候?我似乎無法得到它的工作。
親切的問候, 莫里斯
您需要點擊監聽器附加到返回現場時,複選框狀態保存在cookie所以複選框 – tskulbru 2012-04-29 11:11:42
,狀態被「記住」,因此不使用點擊功能(在這種情況下)。所以它應該靜音的複選框的條件,因爲我已經嘗試過我的不完整的if語句 – Maurice 2012-04-29 23:58:42
