tip: function (msg) {
wx.showModal({
title: '提示',
content: msg,
showCancel: false

format: 'mp3'
});
}

/**
* 停止录音
*/
, stopRecord: function () {
recorderManager.stop()
}

/**
* 播放录音
*/
, playRecord: function () {
var that = this;
var src = this.data.src;
if (src == '') {
this.tip("请先录音！")
return;
}
this.innerAudioContext.src = this.data.src;
this.innerAudioContext.play()
},

onLoad: function (options) {
var that = this;
recorderManager.onError(function () {
that.tip("录音失败！")
});
recorderManager.onStop(function (res) {
that.setData({
src: res.tempFilePath
})
console.log(res.tempFilePath)
that.tip("录音完成！")
});

this.innerAudioContext = wx.createInnerAudioContext();
this.innerAudioContext.onError((res) => {
that.tip("播放录音失败！")
})

}

})
