导火线 : 负责了项目中的话务间模块,处理音频出了一点问题
之前的处理 :
//循环播放声音
var dialAudioDocument = document.createElement(‘audio‘); ?//这是拨号的声音(这里只写了一个音频)var dialSource = document.createElement(‘source‘); ?dialSource.type = "audio/mpeg";dialSource.type = "audio/mpeg";dialSource.autoplay = "autoplay";dialSource.controls = "controls"; ???
url : 表示音频路径,flag : 一个标识,来电还是拨出,audio : 表示上面的dialAudioDocument, source : 上面的dialSourcefunction playAudio(url, flag, audio, source) { ?console.log(url); 注 : 这个的音频要借助source才能播放,并且没有方法让他停止(原因不详) ?console.log(flag); ?console.log(audio); ?console.log(source); ?source.src = url; ?audio.appendChild(source); ?audio.play(); ?if (flag == "dial") { ???dialAlert = setTimeout("playAudio(‘" + url + "‘,‘dial‘, ‘"+audio+"‘, ‘"+source+"‘)", 1000*5); ?} ?if (flag == "call") { ???callAlert = setTimeout("playAudio(‘" + url + "‘,‘call‘, ‘"+audio+"‘, ‘"+source+"‘)", 1000*29); ?}}
// 缺点:由于没有方法让音频停止,这时候只能选取时间短的音频进行循环播放,停止则通过clearInter..的方式停止,而后面换了音频,就不行了.....
当时的小demo : (测试此音频方法是否管用)
<!DOCTYPE html><html><head><meta charset="utf-8"><title>文档标题</title> ???</head><body> <script> ???var t; ???function play2(url){ ???????var audio = document.createElement(‘audio‘); ???????var source = document.createElement(‘source‘); ??????????source.type = "audio/mpeg"; ???????source.type = "audio/mpeg"; ???????source.src = url; ??????????source.autoplay = "autoplay"; ???????source.controls = "controls"; ???????audio.appendChild(source); ????????audio.play(); ???????t = setTimeout("play2(‘"+url+"‘)",2000); ???????????} ???function aa(){ ???????console.log(t); ???????clearTimeout(t); ???????console.log(t); ???????clearTimeout(t); ???} ??</script> ??<input type="button" value="播放" onclick="play2(‘http://down.chinatcc.com/TW_Call_Disconnect.ogg‘)" /> ?<input type="button" value="停止" onclick="aa();" /></body></html>
目前的方案:
<!-- 下面是存放录音 -->
<audio id="dialAudio" src="/static/audio/dialAudio.mp3"></audio>
<audio id="callAudio" src="/static/audio/callAudio.mp3"></audio>
<audio id="hangAudio" src="/static/audio/hangAudio.mp3"></audio>
$(function () {
//初始化录音标签
?dialAudioDocument = document.getElementById(‘dialAudio‘); //这里只能有document得到,原因不详,猜想可能是加载顺序问题
?callAudioDocument = document.getElementById(‘callAudio‘);
?hangAudioDocument = document.getElementById(‘hangAudio‘);
//循环播放声音function playAudio(document, flag) { ?console.log(document); ?document.currentTime = 0; ?document.play(); ?if (flag == "dial") { ???dialAlert = setTimeout("playAudio(‘" + document + "‘,‘dial‘)", 1000*5); ?} ?if (flag == "call") { ???callAlert = setTimeout("playAudio(‘" + document + "‘,‘call‘)", 1000*29); ?}}
//停止掉声音
function pauseAudio(document, flag){
if (flag == "dial") {
document.pause();
}
if (flag == "call") {
document.pause();
}
}
优点:解决了上述的缺点
花时间记录,远大于死敲
