I have a script in my phtml file but I want to only load this ones the page is fully loaded. I am doing a check if my custom module is enabled show the < script >

Adding script like this :

You can achieve this using template call

<referenceContainer name="before.body.end">
        <block class="Magento\Framework\View\Element\Template" template="Namespace_Modulename::before.phtml" name="before_body_js"/>

Can anyone give me a advice or help to figure this out

document.getElementById("demo").innerHTML = "My First JavaScript";

I have to use this as well

<script type="text/javascript">
  alert("This alert box was called with the onload event");

If it's a script, you can try wrapping your script code inside

$( document ).ready(function() {
 // Your code

This will ensure that your code written inside will be reflected once the page is loaded.

domReady! - You can use this feature of the RequireJS like the native Magento's modules use:

        ], function($) {
            // Your Code

DOMContentLoaded - Executes after DOM is loaded (before img and css):

document.addEventListener("DOMContentLoaded", function(){
    document.getElementById("demo").innerHTML = "My First JavaScript";

load - Executes after everything is loaded and parsed:

window.addEventListener("load", function(){
    document.getElementById("demo").innerHTML = "My First JavaScript";
