今天來介紹一下微信小程式中音訊播放控制元件–audio
1.效果圖如下,
2.index.js中:
//index.js
//獲取應用例項
const app = getApp()
var isLoop = true;
var isControls = true;
Page({
onReady: function (e) {
// 使用 wx.createAudioContext 獲取 audio 上下文 context
this.audioCtx = wx.createAudioContext('myAudio')
},
data: {
poster: 'http://y.gtimg.cn/music/photo_new/T002R300x300M000003rsKF44GyaSk.jpg?max_age=2592000' ,

controls: true
},
onLoad: function () {
},
//開始播放
audioPlay: function () {
this.audioCtx.play()
},
//暫停播放
audioPause: function () {
this.audioCtx.pause()
},
//設定進度到57秒
audio57: function () {
this.audioCtx.seek(57)
},
//重新開始播放
audioStart: function () {
this.audioCtx.seek(0)
},
//設定是否輪播播放
audioLoop: function () {
if (isLoop == true) {
isLoop = false;
this.setData({
loop: true,
controls: true
})
} else {
isLoop = true;
this.setData({
loop: false,
controls: false
})
}
},
//設定是否顯示預設控制元件
audioControls:function(){
if (isControls == true){
isControls = false;
this.setData({
controls:false
})
}else{
isControls = true;
this.setData({
controls: true
})
}
}
})
3.index.wxml中:
<!-- audio.wxml -->
<audio class="audio" poster="{{poster}}" name="{{name}}" author="{{author}}" src="{{src}}" id="myAudio" controls="{{controls}}" loop="{{loop}}"></audio>
<button class="btn" type="primary" bindtap="audioPlay">播放</button>
<button class="btn" type="primary" bindtap="audioPause">暫停</button>
<button class="btn" type="primary" bindtap="audio57">設定當前播放時間為57秒</button>
<button class="btn" type="primary" bindtap="audioStart">從頭開始</button>
<button class="btn" type="primary" bindtap="audioLoop">設定/取消迴圈播放</button>
<button class="btn" type="primary" bindtap="audioControls">顯示/取消預設控制元件</button>
4.index.wxss中:
.btn{
margin-top: 15rpx;
}
.audio{
margin-left: 65rpx;
}
