Recording player module

Technology stack used (Vue3.0 +typeScript+Element Plus)

Packaging as components is recommended for use in existing projects. Vue2. X can be modified to not support TS, you can remove the related type judgment, you need different styles, you can define your own styles

H5 Audio Related events and attributes

    <audio
        ref="audio"
        class="audioStyle"
        :src="url"
        :preload="audioState.preload"
        @play="onPlay"
        @error="onError"
        @waiting="onWaiting"
        @pause="onPause"
        @timeupdate="onTimeupdate"
        @loadedmetadata="onLoadedmetadata"
    >
    </audio>
Copy the code

1.SRC is the address of the audio2.The preload attribute specifies whether audio is loaded after the page is loaded - Auto loads the entire audio after the page is loaded - Meta loads only metadata after the page is loaded - None loads no audio after the page is loaded3.OnPlay Play method4.OnPause Pause method5.OnTimeupdate The progress bar can also be updated when the timeUpdate event is used to update the current playback time of the audio stream approximately once per second6.Loadedmetadata Duration for loading audio filesCopy the code

Define the styles and methods used to play recordings

1.OnLoadedmetadata is used to load the audioconst onLoadedmetadata = (res) = > {
    state.audioState.waiting = false
    state.audioState.maxTime = parseInt(res.target.duration)
}
2.Click the pause or play button to invoke audio's corresponding functionconst audio = ref(); // Vue3. X is not written here
const startPlayOrPause=() = > {
    return state.audioState.playing ? pausePlay() : startPlay()
}
// Start playing
const startPlay =() = > {
    audio.value.play()
}
/ / pause
const pausePlay = () = > {
    audio.value.pause()
}
3.Drag the progress bar to update the playback time in real time// Play jump
const changeCurrentTime = (index) = > {
    audio.value.currentTime = Math.floor((index) / 100 * state.audioState.maxTime))
}
4.Change the volume// The volume is changed through audio's volume property
const changeVolume = (index = 0) = > {
    audio.value.volume = Number(index) / 100
    state.volume = index
}
5.Downloading recording Filesconst downloadFile=() = >{
    let temurl=state.url.split('. ').slice(-2) [0].split('/').slice(-1) [0]
    var laststr=temurl.lastIndexOf('_');
    var newStr=temurl.substring(0,laststr);
    let itemName=newStr
    download(state.url,itemName)
}
const download =(url, filename) = > {
    url=url+`?The ${Math.random()}`
    getBlob(url, function(blob:any) { saveAs(blob, filename); })}const getBlob=(url:String,cb:any) = > {
    var xhr:any = new XMLHttpRequest();
    xhr.open('GET', url, true);
    xhr.responseType = 'blob';
    xhr.onload = function() {
        if (xhr.status === 200) { cb(xhr.response); }}; xhr.send(); }const saveAs=(blob, filename) = > {
    var link:any = document.createElement('a');
    var body:any = document.querySelector('body');
    link.href = window.URL.createObjectURL(blob);
    link.download = filename;
    // fix Firefox
    link.style.display = 'none';
    body.appendChild(link);
    link.click();
    body.removeChild(link);
    window.URL.revokeObjectURL(link.href);
}
6.Fast forward by modifying audio's playbackRate propertyconst changeSpeed =() = > {
    let index = state.speeds.indexOf(state.audioState.speed) + 1
    state.audioState.speed = state.speeds[index % state.speeds.length]
    audio.value.playbackRate = state.audioState.speed
}
