目前解决方法只有如下： [代码]const innerAudioContext1 = wx.createInnerAudioContext()[代码][代码]innerAudioContext1.src = [代码][代码]'audio/piano/c4.mp3'[代码] [代码] [代码][代码]const innerAudioContext2 = wx.createInnerAudioContext()[代码][代码] [代码][代码]innerAudioContext2.src = [代码][代码]'audio/piano/e4.wav'[代码] [代码] [代码][代码]const innerAudioContext3 = wx.createInnerAudioContext()[代码][代码] [代码][代码]innerAudioContext3.src = [代码][代码]'audio/piano/g4.wav'[代码] [代码] [代码][代码]innerAudioContext1.play()[代码][代码] [代码][代码]innerAudioContext2.play()[代码][代码] [代码][代码]innerAudioContext3.play()[代码] 但个人认为这不是非常严格的“同时播放”。 JS是单线程的，三个音频顺序执行了，只是时间差别在ms级听不出来先后而已。
