由于微信小程序官方将音频的样式固定死了,往往再工作中和UI设计师设计出来的样式不符,故一般都采用背景音频播放来实现自定义的UI样式的音频播放,即使用官网API提供的BackgroundAudioManager进行操作 也可以去官网https://developers.weixin.qq.com/miniprogram/dev/api/media/background-audio/BackgroundAudioManager.play.html查看详情 第一步,在对应的wxml页面添加如下代码,eg,放在index.wxml中 <view class='audioMeaage'> <view bindtap='playAudio1'> <image wx:if="{{!audioImg}}" class='playIcom' src='{{palyIcon}}'></image> <image wx:else class='playIcom' src='{{pausIcon}}'></image> </view> <view class='sliderWrap'> <view class='audioNames'>{{audioTitle}}</view> <view class='progressWrap'> <slider class="slider2" bindchange="hanle_slider_change" bindtouchstart="handle_slider_move_start" bindtouchend="handle_slider_move_end" min="0" block-size="10" max="{{slider_max}}" activeColor="#ffd038" block-color="#ffd038" backgroundColor="#f2f2f2" value="{{slider_value}}" /> <view class='proTime'>{{current_process}}/{{total_process}}</view> </view> </view> </view> 第二步,对应的index.js,注意这里的playAudio方法是点击以后从后台获取音频的url和标题等信息的 //获取应用实例
const app = getApp()
const AUDIOMANAGER = getApp().globalData.global_bac_audio_manager.manage
const AUDIO = getApp().globalData.global_bac_audio_manager
Page({
data: {
audioImg:false,
palyIcon: "./../../images/home_img_vedio_play.png",
pausIcon:"./../../images/home_img_vedio_play2.png",
audioFlag: false,
is_moving_slider: false,
current_process:"",
slider_value: "",
total_process: "",
slider_max: "",
audioTitle:"",
},
playAudio: function(e){
const item = e.currentTarget.dataset.url
AUDIOMANAGER.src = item.link_url
AUDIOMANAGER.title = item.tit // 音频标题
AUDIO.is_play= true
//背景音频播放进度更新事件
const that = this
that.setData({
audioFlag: true,
audioTitle: item.tit,
audioImg: true
})
AUDIOMANAGER.onTimeUpdate(() => {
if (!that.data.is_moving_slider) {
that.setData({
current_process: that.format(AUDIOMANAGER.currentTime),
slider_value: Math.floor(AUDIOMANAGER.currentTime),
total_process: that.format(AUDIOMANAGER.duration),
slider_max: Math.floor(AUDIOMANAGER.duration)
})
}
AUDIO.time = AUDIOMANAGER.currentTime
})
// 背景音频播放完毕
AUDIOMANAGER.onEnded(() => {
// 单曲循环
that.setData({
slider_value: 0,
current_process: '00:00',
total_process: that.format(AUDIOMANAGER.duration)
})
})
},
// 拖动进度条,到指定位置
hanle_slider_change(e) {
const position = e.detail.value
this.seekCurrentAudio(position)
},
// 拖动进度条控件
seekCurrentAudio(position) {
// 更新进度条
let that = this
wx.seekBackgroundAudio({
position: Math.floor(position),
success: function () {
AUDIOMANAGER.currentTime = position
that.setData({
current_process: that.format(position),
slider_value: Math.floor(position)
})
}
})
},
// 进度条滑动
handle_slider_move_start() {
this.setData({
is_moving_slider: true
});
},
handle_slider_move_end() {
this.setData({
is_moving_slider: false
});
},
// 时间格式化
format: function(t) {
let time = Math.floor(t / 60) >= 10 ? Math.floor(t / 60) : '0' + Math.floor(t / 60)
t = time + ':' + ((t % 60) / 100).toFixed(2).slice(-2)
return t
},
// 播放音频
playAudio1: function(){
console.log(9799875)
console.log(AUDIO.is_play)
if(AUDIO.is_play) {
AUDIOMANAGER.pause()
AUDIO.is_play = false
this.setData({
audioImg: false
})
} else {
AUDIOMANAGER.play()
AUDIO.is_play = true
this.setData({
audioImg: true
})
}
},
})
第三步,由于index.js里引入了app.js的方法或者属性了,其实就是将AUDIO的方法提出来了,放在了一个公用的里面,自己单独建立公用文件或者直接写在app.js里都是可以的,这里将其放在app.js中,可以对应这修改globalData里的属性 globalData: {
userInfo: null,
global_bac_audio_manager: {
manage: wx.getBackgroundAudioManager(),
is_play: false,
id: '',
play_time: '',
article_id: '',
}
}
index.wxss .audioMeaage{
height: 124rpx;
display: flex;
align-items: center;
}
.proTime{
font-size: 20rpx;
color: #888888;
}
.progressWrap{
display: flex;
align-items: center;
}
.playIcom{
width: 84rpx;
height: 84rpx;
}
.slider{
/* width: 502rpx; */
}
.slider1{
width: 466rpx;
margin:0 29rpx 0 8rpx;
}
.slider2{
width: 466rpx;
margin:0 29rpx 0 19rpx;
}
