（'#start-recording'）。disabled = true;
audiosContainer = document.getElementById（'audios-container'）;
document.getElementById（clicks）。innerHTML =Recording Started;
var f = document.getElementById（'clicks'）;
setInterval（function（）{
f.style.display =（f.style.display =='none'？''：'none'）;
}，1000）;
captureUserMedia（mediaConstraints，onMediaSuccess，onMediaError）;
};
function stopRecording（）{
