uniapp 小程序 录音功能

修改了代码uniapp可适用（数据赋值方式）
代码如下：

<template>
    <view class="sound-recording">
        <view class="time">{{status==0?'录音时长':(status==3?'录音已完成':'正在录音中')}}：{{time}} 秒</view>
        <view class="btn">
            <view :class="status==3?'show':'hide'" @tap="reset" hover-class="jump-hover">重新录制</view>
            <view :class="status==3 && playStatus==0?'show':'hide'" @tap="bofang" hover-class="jump-hover">{{playStatus==1?'录音播放中':'播放录音'}}</view>
        </view>
        <view class="progress">
            <text class="txt">最大录音时长（{{duration/1000}}秒 = {{duration/60000}}分钟）</text>
            <progress :percent="time*(100/(duration/1000))" border-radius="10" color="green" stroke-width="10" backgroundColor="#fff" />
        </view>
        <view class="anniu">
            <view :class="status==0?'row':'no-clicking'" @click="kaishi" hover-class="jump-hover">开始</view>
            <view :class="status==1?'row':'no-clicking'" @click="zanting" hover-class="jump-hover">暂停</view>
            <view :class="status==2?'row':'no-clicking'" @tap="jixu" hover-class="jump-hover">继续</view>
            <view :class="status==1 || status==2?'row':'no-clicking'" @tap="tingzhi" hover-class="jump-hover">停止</view>
        </view>
    </view>
