Vue uses the table component of elementui to play audio on every line, and after turning the page, the audio of the corresponding line on the previous page is played.

use the table component of elementui to play audio. After turning the page, the content is played for the first time

.

the source code is as follows: 

<template>
  <div >

the only difference between the above two pieces of code is whether it is set before the request. I don"t know why 

this.tableData = []

what result do you expect? What is the error message actually seen?

Audio-player element-ui vue.js javascript
May.08,2022

encounters similar problems: the solution is to modify
< source: src= "scope.row.audiourl" type= "audio/mpeg" / > < / audio >
to < / audio >
so that it can be played normally when playing the audio on the second page

when you use the id assigned to audio by audiourl , have you considered that audiourl is empty.
I think the code for your audio playback should be written like this, assigning the index to id, preceded by a letter, so that each audio is a unique

. 
<source :src="scope.row.audiourl"  type="audio/mpeg" /></audio>
</el-button>

when you get the audio, pass in the index index, and directly document.getElementById ('audio'+index) , and play with this audio when playing
. As for the playback after turning the page or the previous page, the src is the same, and you may need to overwrite the src
