The element refuses to accept the appendChild method

I've created a tampermonkey script that generates certain elements and adds them to the page.

The first element, named ControllerBG, is appended to an element with the id "motd".

However, when I try to append a second element, nothing appears on the page and no errors are shown in the console.

For example:

ControllerBG.appendChild(TopContainer);

Only the first variable/element gets appended, resulting in something like this:

<div class="ControllerBG" item-controlv1=""></div>

Why aren't the other elements being added to the variable "TopContainer"?

You can view the JavaScript code in my JSFIDDLE link here:

https://jsfiddle.net/60nzjxf3/

I even attempted to use:

ControllerBG.innerHTML = TopContainer

Answer №1

Appending the TopContainer onto multiple elements may lead to overlooking its placement, with only the final one (AboutContent) actually receiving it. Furthermore, failing to append this element to the document can cause issues.

ControllerBG.innerHTML = TopContainer
will not function as expected since TopContainer is an element and not an HTML string.
