javascript - How to replace HTML tag with js script during DOM creation -

i'm trying solve issue. have cms , i'm using ckeditor create html wysiwyg editor.

i want insert in html components (javascript): ckeditor of course cannot manage these components create plugin create placeholder.

the result html this:

<p>sample text</p> <p><widget data_id="2" data_type="gallery"></widget></p> <p>sample text</p>

now need replace during page load <widget> tag widget. have api call can return gallery images or html snippet.

i don't want use iframe, think use vuejs render components never use it. other idea? ajax?

you can use

$(document).onload(function(){  //type code here  });
