唱片旋转的效果使用CSS3动画。唱片随歌曲播放和暂停。
<view class="m-song-light a-circling" style="animation-play-state:{{state}}">
设定state的状态，‘ ’或者‘pause’
music.onPlay(() => { that.setData({ playStatus: true, state: ' ' }) this.setCurrentIndex(); }); music.onPause(() => { console.log('pause'); that.setData({ playStatus: false, state: 'paused' }) });
2. 播放slide采用了微信小程序的表单组件silder
<view class="slid"> <view> <text class='times'>{{currentTime}}</text> </view> <slider bindchange="sliderChange" activeColor="#d33a31" block-size="12" backgroundColor="#999" value="{{percent}}" > </slider> <view> <text class='times'>{{duration}}</text> </view> </view>
获取数据：currentTime duration
处理数据：percent
data: {
currentTime:'00:00',
duration:' ',
percent:' ',
}
formatTime: function(time) {
var minute =Math.ceil(time/60)%60;
var sec = Math.ceil(time)%60;
return (minute<10? '0'+minute : minute) + ':' + (sec<10 ? '0' +sec : sec)
},
music.onTimeUpdate(() =>{ let duration = that.formatTime(music.duration); let currentTime = that.formatTime(music.currentTime); let percent =(music.currentTime/music.duration*100).toFixed(2); // console.log(music.duration +'--'+ percent +'--'+ music.currentTime); that.setData({ duration:duration, currentTime: currentTime, percent:percent, musicTime:parseInt(music.currentTime) }); });
//滑块滑动jS
sliderChange: function(e) {
var that=this;
// that.data.music.pause();
let slideValue = e.detail.value;
let seeKPosition = that.data.music.duration/100*slideValue
that.data.music.seek(seeKPosition);
// console.log(currentTime)
setTimeout(function () {
that.data.music.play();
}, 500);
},
获取歌词并设定歌词滚动
//歌词处理，得到的歌词需要经过处理才能使用 dealLrc: function(lrc) { // let lrc = this.data.musicLyric; var that=this; var arr = lrc.split(" "); var timeArr = [], lrcArr = []; arr.forEach(function (item, index) { var time = item.slice(item.indexOf("["), item.indexOf("]") + 1); time = that.dealLrcTime(time); timeArr.push(time); var lrc = item.substr(item.indexOf("]") + 1)+" "; lrcArr.push(lrc); // console.log(time) }); // console.log(lrcArr) // console.log(timeArr) that.setData({ lyrics: lrcArr, lyricsTime:timeArr }); }, dealLrcTime: function(time) { time = time.replace("[", ""); time = time.replace("]", ""); var arr = time.split(":"); var relTime = parseInt(arr[0]) * 60 + parseInt(arr[1]); return relTime; }, //找到当前播放时间 findCurrentIndex(curTime,timeArr) { // var curTime = this.data.musicTime; // var timeArr = this.data.lyricsTime; var index = -1; for (let i = 0; i < timeArr.length; ++i) { if (timeArr[i] == NaN) { continue; } if (curTime <= timeArr[i]) { index = i; break; } } return index; }, //设置当前歌曲播放的位置 setCurrentIndex:function(){ var timeId=wx.getStorageSync("timeId"); if(timeId){ clearInterval(timeId); } if(this.data.musicLyric){ // var audio = this.data.audio; // var duration = audio.duration; var timeArr = this.data.lyricsTime; var currentTime = -1; var that = this; timeId = setInterval(() => { currentTime = that.data.musicTime; var currentIndex =that.findCurrentIndex(currentTime, timeArr); this.setData({ currentIndex: currentIndex }); }, 2000); wx.setStorageSync("timeId", timeId); } }, onLoad: async function (options) { // console.log(options.title); // const url = `/song/detail?ids=${options.id}`; var that=this; const url = `/song/url?id=${options.id}`; const lyric=`/lyric/?id=${options.id}`; const songDetail=`/song/detail?ids=${options.id}`; const res = await requestUrl.get(url); const res_lyric= await requestUrl.get(lyric); const res_songDetail= await requestUrl.get(songDetail); const musicLyric = that.dealLrc(res_lyric.data.lrc.lyric); // const palyMusicUrl = res.data.data[0].url; // console.log(res_lyric.data.lrc.lyric); // console.log(res_songDetail.data.songs); this.setData({ palyMusicUrl: res.data.data[0].url, playTitle: options.title, // musicLyric: res_lyric.data.lrc.lyric, songDetail: res_songDetail.data.songs[0] }); this.playMusic(); // this.dealLrc(); // console.log(res.data); // this.time(); },

歌词滚动，获取当前所在的歌词位置，CSS控制歌词向上滚动
