微信小程序-自定义语音输入
最近有写一个自定义的语音输入界面,大概流程与正常微信发语音的流程相仿.效果截图如下:

下面贴代码了:(代码很长,可直接复制运行,效果会比较直观)

js:

this.setData({

this.startVoiceRecordAnimation();
var that = this;

console.log('recorder stop', res)
const { tempFilePath } = res;
if (res.duration < 1000) {
wx.showToast({

} else {
recordLength = (res.duration / 1000) / 60 * 440;
}
var recordTime = (res.duration / 1000).toFixed(0);
console.log('recordLength' + recordLength);
that.setData({
recordingLength: recordLength,
recordingTime: recordTime,
voiceTempFilePath: tempFilePath,
selectResource: true,
showVoiceMask: false,
startRecording: false
})
that.stopVoiceRecordAnimation();
}
} else {
that.setData({

cancleRecording:false
})
that.stopVoiceRecordAnimation();
}
})
},
//向上滑动取消录音
moveToCancle: function (event) {
let currentY = event.touches[0].pageY;
if (this.data.lastVoiceYPostion !== 0) {
if (currentY - this.data.lastVoiceYPostion < 0 && currentY < 470) {
this.setData({
cancleRecording:true
})
}
}
this.setData({
lastVoiceYPostion: currentY
})
},
//麦克风帧动画
startVoiceRecordAnimation:function () {
var that = this;
//话筒帧动画
var i = 1;
that.data.recordAnimationSetInter = setInterval(function () {
i++;
i = i % 5;
that.setData({
recordAnimationNum: i
})
}, 300);
},
// 停止麦克风动画计时器
stopVoiceRecordAnimation:function () {
var that = this;
clearInterval(that.data.recordAnimationSetInter);
},
以上就是关于这个界面的实现代码啦,写的不好还请多多指教.
还有关于录音之后播放音频的相关问题,请查看我的上一篇帖子:微信小程序-InnerAudioContext()播放音频
谢谢大家~~
