audioContext对象的方法列表:
<!-- audio.wxml --> <audio src="{{src}}" id="myAudio" ></audio> <button type="primary" bindtap="audioPlay">播放</button> <button type="primary" bindtap="audioPause">暂停</button> <button type="primary" bindtap="audio14">设置当前播放时间为14秒</button> <button type="primary" bindtap="audioStart">回到开头</button>
// audio.js Page({ onReady: function (e) { // 使用 wx.createAudioContext 获取 audio 上下文 context this.audioCtx = wx.createAudioContext('myAudio') }, data: { src: 'http://ws.stream.qqmusic.qq.com/M500001VfvsJ21xFqb.mp3?guid=ffffffff82def4af4b12b3cd9337d5e7&uin=346897220&vkey=6292F51E1E384E06DCBDC9AB7C49FD713D632D313AC4858BACB8DDD29067D3C601481D36E62053BF8DFEAF74C0A5CCFADD6471160CAF3E6A&fromtag=46', }, audioPlay: function () { this.audioCtx.play() }, audioPause: function () { this.audioCtx.pause() }, audio14: function () { this.audioCtx.seek(14) }, audioStart: function () { this.audioCtx.seek(0) } })
