今天記錄一下audio的基本使用,首先看下效果圖。(聲音請(qǐng)腦補(bǔ)一下~)
1.audio屬性(自行去微信官方文檔中了解) 2.一起看一下 audio.wxml <audio id="myAudio" poster="{{poster}}" name="{{name}}" author="{{author}}" src="{{src}}" bindplay="bindPlay" bindpause='bindPause' bindended='bindEnd' binderror='bindError' bindtimeupdate='bindTimeUpdate' controls loop>audio> <button type="primary" class="audioButton" bindtap="audioPlay">播放button> <button type="primary" class="audioButton" bindtap="audioPause">暫停button> <button type="primary" class="audioButton" bindtap="audio14">設(shè)置當(dāng)前播放時(shí)間為14秒button> <button type="primary" class="audioButton" bindtap="audioStart">回到開(kāi)頭button> ①id為audio組件的唯一標(biāo)識(shí),在js中通過(guò)該id獲取audio上下文context this.audioCtx = wx.createAudioContext('myAudio')
②poster、name、author、src為audio資源,詳見(jiàn)屬性表 bindPlay: function () {//監(jiān)聽(tīng)音樂(lè)開(kāi)始/繼續(xù)播放 console.log("<" + this.data.name + '>繼續(xù)播放') }, bindPause: function () {//監(jiān)聽(tīng)音樂(lè)暫停 console.log("<" + this.data.name + '>暫停播放') }, bindEnd: function () {//監(jiān)聽(tīng)音樂(lè)播放結(jié)束 console.log("<" + this.data.name + '>結(jié)束播放') }, ④binderror監(jiān)聽(tīng)audio的錯(cuò)誤 bindError: function (error) {//監(jiān)聽(tīng)錯(cuò)誤,錯(cuò)誤信息error.detail.errMsg console.log(error.detail.errMsg) },
其中errMsg有四種 bindTimeUpdate:function(timeupdate){ console.log("當(dāng)前播放位置:"+timeupdate.detail.currentTime+"s") },
⑥loop為true則音樂(lè)自動(dòng)循環(huán)播放
2.完整的js代碼↓ Page({ onReady: function (e) { // 使用 wx.createAudioContext 獲取 audio 上下文 context this.audioCtx = wx.createAudioContext('myAudio') }, data: { // poster: '../../resources/image/隔壁團(tuán).jpg', // name: '夏天海邊', // author: '隔壁團(tuán)樂(lè)隊(duì)', // src: '../../resources/audio/夏天海邊.mp3', src: 'http://ws.stream.qqmusic.qq.com/M500001VfvsJ21xFqb.mp3?guid=ffffffff82def4af4b12b3cd9337d5e7&uin=346897220&vkey=6292F51E1E384E06DCBDC9AB7C49FD713D632D313AC4858BACB8DDD29067D3C601481D36E62053BF8DFEAF74C0A5CCFADD6471160CAF3E6A&fromtag=46', poster: 'http://y.gtimg.cn/music/photo_new/T002R300x300M000003rsKF44GyaSk.jpg?max_age=2592000', name: '此時(shí)此刻', author: '許巍' }, bindPlay: function () {//監(jiān)聽(tīng)音樂(lè)開(kāi)始/繼續(xù)播放 console.log("<" + this.data.name + '>繼續(xù)播放') }, bindPause: function () {//監(jiān)聽(tīng)音樂(lè)暫停 console.log("<" + this.data.name + '>暫停播放') }, bindEnd: function () {//監(jiān)聽(tīng)音樂(lè)播放結(jié)束 console.log("<" + this.data.name + '>結(jié)束播放') }, bindError: function (error) {//監(jiān)聽(tīng)錯(cuò)誤,錯(cuò)誤信息error.detail.errMsg console.log("=================================") console.log(error.detail.errMsg) console.log("=================================") }, bindTimeUpdate:function(timeupdate){ console.log("當(dāng)前播放位置:"+timeupdate.detail.currentTime+"s") }, audioPlay: function () {//點(diǎn)擊“播放”觸發(fā) this.audioCtx.play() }, audioPause: function () {//點(diǎn)擊“暫停”觸發(fā) this.audioCtx.pause() }, audio14: function () {//設(shè)置當(dāng)前播放時(shí)間為14秒,seek單位為s this.audioCtx.seek(14) }, audioStart: function () { this.audioCtx.seek(0) } })
audioContext 對(duì)象的方法列表: 3.wxss樣式文件↓ /* pages/audio/audio.wxss */ .audioButton{ margin-left: 20px; margin-right: 20px; margin-top: 20px; }
使用本地資源后,其他功能都不受影響,但是seek(14)有bug,每次都是從頭開(kāi)始播放。不知道是不是小程序的bug難過(guò)。今天關(guān)于audio的部分就記錄到這里啦 |
