The process is relatively simple and mainly consists of the following steps:

Register plug-in (button, Lang, htmlTags, plug-in script)
Modified based on media plug-in code

Register plugin

First, configure the kindeditor parameters globally:

KindEditor.lang({
 audio : 'MP3'
});
 KindEditor.options.htmlTags['audio'] = ['src','controls','autoplay','type'];
 KindEditor.options.htmlTags['source'] = ['src','controls','autoplay','type'];

Copy after login

In the place where you initialize the editor, configure the button list items parameter and put
'audio'
Put it in the right place:

KindEditor.ready(function(K) {
editor = K.create('#info,#spread_info', {
  //其他配置省略...
  items : [
    'source', '|', 'undo', 'redo', '|', 'preview', 'print', 'template', 'code', 'cut', 'copy', 'paste',
    'plainpaste', 'wordpaste', '|', 'justifyleft', 'justifycenter', 'justifyright',
    'justifyfull', 'insertorderedlist', 'insertunorderedlist', 'indent', 'outdent', 'subscript',
    'superscript', 'clearhtml', 'quickformat', 'selectall', '|', 'fullscreen', '/',
    'formatblock', 'fontname', 'fontsize', '|', 'forecolor', 'hilitecolor', 'bold',
    'italic', 'underline', 'strikethrough', 'lineheight', 'removeformat', '|', 'image', 'multiimage',
     '|' ,'table', 'hr', 'emoticons', 'baidumap', 'pagebreak',
    'anchor', 'link', 'unlink', '|', 'about','audio'
  ]
});

Copy after login

For easier reading, I put the audio button at the end, after the "Help" label.

In order for the button to be displayed, we also need to specify the css style:

<style>
  .ke-icon-audio {
    background-position: 0px -528px;
    width: 16px;
    height: 16px;
  }
</style>

Copy after login

For convenience, I directly used the icons of the built-in audio and video buttons. To customize the icons, please manually specify the background style attribute.

Finally, create the script

kindeditor/plugins/audio/audio.js

Copy after login

The audio directory is created manually.

We put

plugins/media/media.js

Copy after login

Copy the code in

to audio.js, and then start modifying it.

Modify media plug-in

The main thing is to remove some useless attributes, such as width, height, autoplay, etc., and modify the inserted code part, and manually build the html code of the "audio" tag.

KindEditor.plugin('audio', function(K) {
  var self = this, name = 'audio', lang = self.lang(name + '.'),

      if (allowFileManager) {

    }
  };
  self.clickToolbar(name, self.plugin.media.edit);
});

Copy after login

At this point, the entire plug-in is basically finished.

It should be noted that uploading files uses the common configuration uploadJson parameter, but a get parameter "dir=audio" will be automatically added when uploading to facilitate background recognition:

url : K.addParam(uploadJson, 'dir=audio'),
