var duration = innerAudioContext.duration;

console.log(duration)

var min = parseInt(duration / 60);

var sec = parseInt(duration % 60);

if (min.toString().length == 1) {

min = `0${min}`;

}

if (sec.toString().length == 1) {

sec = `0${sec}`;

}

t.setData({

audioDuration: innerAudioContext.duration,

showTime2: `${min}:${sec}`

});

}, 1000)

})

},

输出的duration是0
