基于React 的audio音频播放组件

基于React 的audio音频播放组件, 自定义播放/暂停按钮、进度条调节、音量调节、倍速播放。

组件代码:

AudioPlay.js

import React, { Component } from "react";

class App extends Component {
  constructor(props) {
    super(props);
    this.state = {
      rateList: [1.0, 1.25, 1.5, 2.0],
      playRate: 1.0,
      isPlay: false,
      isMuted: false,
      volume: 100,
      allTime: 0,
      currentTime: 0,
    };
  }

  componentDidMount() {}

  formatSecond(time) {
    const second = Math.floor(time % 60);
    let minite = Math.floor(time / 60);
    return `${minite}:${second >= 10 ? second : `0${second}`}`;
  }

  // 该视频已准备好开始播放
  onCanPlay = () => {
    const { id } = this.props;
    const audio = document.getElementById(`audio${id}`);
    this.setState({
      allTime: audio.duration,
    });
  };

  playAudio = () => {
    const { id } = this.props;
    const audio = document.getElementById(`audio${id}`);
    audio.play();
    this.setState({
      isPlay: true,
    });
  };

  pauseAudio = () => {
    const { id } = this.props;
    const audio = document.getElementById(`audio${id}`);
    audio.pause();
    this.setState({

    });
  };

    const { id } = this.props;
    const audio = document.getElementById(`audio${id}`);
    this.setState({

    });
    audio.muted = !audio.muted;
  };

  changeTime = (e) => {
    const { value } = e.target;
    const { id } = this.props;
    const audio = document.getElementById(`audio${id}`);
    this.setState({

    audio.currentTime = value;
    if (value === audio.duration) {

    const { id } = this.props;
    const audio = document.getElementById(`audio${id}`);
    audio.volume = value / 100;

    this.setState({
      volume: value,
      isMuted: !value,
    });
  };

  // 倍速播放
  changePlayRate = (num) => {
