Realize the listening function of reading software, adapt to apps, small programs, and h5
The effect display function brings you: Chapter, countdown, previous chapter, next chapter, play, pause, double speed:
uniapp official uni.createInnerAudioContext() document address: official website document reference address
First introduce the function step by step:
- Chapter (this call interface can traverse the data and display it in the form of a pop-up layer)
- Countdown
- Previous chapter
- next chapter
- play
- pause
- double speed
I embed an audio component on this page, and the component name is audio.

this.bgAudioMannager.pause()

// 点击进度条
clickSeek(val) {

For the previous chapter and the next chapter, our chapter directory structure is two-level. The logic is to find the corresponding chapter in the chapter array based on the chapter id that is clicked, and then take its previous node or next node. Note: Replace the obtained id with the current id
