Automatic closure of the div tag in JavaScript

I am revamping my website to a more modern web application, and here is the HTML code I am using:

<joexn-profile>
<joexn-logo></joexn-logo>
<joexn-text></joexn-text>
</joexn-profile>

Additionally, here is the JavaScript code that I have implemented for the <joexn-profile> tags:

var joexnprofile = document.querySelector('joexn-profile');
joexnprofile.insertAdjacentHTML( 'afterBegin', '<center><div class="joexn-profile">');
joexnprofile.insertAdjacentHTML( 'afterEnd', '</div></center>');

However, I have encountered an issue where the 

<div class="joexn-profile">
tag automatically closes. Please refer to the inspect element view below:

Answer №1

Quentin has already pointed out that inserting only half of a Node is not possible.

However, the bigger question is why would you even want to do that in the first place?

Firstly, it's best to avoid tags like <center>, <font>, or <b>. Use CSS for styling instead.

Secondly, what's the purpose of replacing <joexn-profile> with 

<div class="joexn-profile">
? You can apply styles to both selectors in the same way.

The only difference is that you need to declare display:block for joexn-profile so the browser knows how to render this Node as either block or inline.

If you still wish to proceed in your own way, here is a helpful utility for managing compositions of html-markup (even partial) and DOM-Nodes.

Note: The code provided has not been fully tested and may contain bugs. Also, fragment() does not handle cyclic references!

Answer №2

Even with the convenience of insertAdjacentHTML, remember that you are interacting with a structured DOM. This means working with elements in a specific hierarchy rather than traditional start and end tags.

Your HTML content will be translated into DOM nodes for insertion, so you're not directly modifying the original source code.

Consider utilizing createElement as an alternative approach. Select the desired element within the new element using querySelector, then utilize appendChild to transfer it into its new location.
