摘要：小程序无法成功切换音频的playbackrate
展开：请问大家有没有遇到这种问题呢我即使按照官方示例，把code直接复制粘贴到我的开发者工具里，也是无法切换音频的播放速度。示例如下：示例代码：action的method属性只能是play、pause、setPlaybackRate、setCurrentTime，用法如下：!循环播放audioposter{{poster}}name{{name}}author{{author}}src{{src}}action{{action}}controlsloop/audiobuttontypeprimarybindtapaudioPlay播放/buttonbuttontypeprimarybindtapaudioPause暂停/buttonbuttontypeprimarybindtapaudioPlaybackRateSpeedUp调为2倍速/buttonbuttontypeprimarybindtapaudioPlaybackRateNormal调为1倍速/buttonbuttontypeprimarybindtapaudioPlaybackRateSlowDown调为0.5倍速/buttonbuttontypeprimarybindtapaudio14设置当前播放时间为14秒/buttonbuttontypeprimarybindtapaudioStart回到开头/button//appservicePage({data:{poster:http://y.gtimg.cn/music/photo_new/T002R300x300M000003rsKF44GyaSk.jpg?max_age2592000,name:此时此刻,author:许巍,src:http://ws.stream.qqmusic.qq.com/M500001VfvsJ21xFqb.mp3?guidffffffff82def4af4b12b3cd9337d5e7uin346897220vkey6292F51E1E384E06DCBDC9AB7C49FD713D632D313AC4858BACB8DDD29067D3C601481D36E62053BF8DFEAF74C0A5CCFADD6471160CAF3E6Afromtag46,},audioPlay:function(){this.setData({action:{method:play}})},audioPause:function(){this.setData({action:{method:pause}})},audioPlaybackRateSpeedUp:function(){this.setData({action:{method:setPlaybackRate,data:2}})},audioPlaybackRateNormal:function(){this.setData({action:{method:setPlaybackRate,data:1}})},audioPlaybackRateSlowDown:function(){this.setData({action:{method:setPlaybackRate,data:0.5}})},audio14:function(){this.setData({action:{method:setCurrentTime,data:14}})},audioStart:function(){this.setData({action:{method:setCurrentTime,data:0}})}})谢谢！
