Is there anyway to detect a variant change in Shopify using an external Javascipt/jquery file?

I have written a external JS script that shows a custom text on the stores product's page. Currently the JS function is called once, on the window.onload function.

I want my script to be able to detect a variant change and swap out the text to a different one, whenever a different variant is selected. How do I detect a variant change and get it's price in an external JS file, using only JS/jQuery function.


My code in shopify store:
<script id="testscript" src="${{ product.price | divided_by: 100.00 | round: 2 }}"></script>
<div id="mydiv"></div>

My code in test.js:
window.onload = function () {
    document.getElementById("mydiv").innerHTML += ("<p>This is a test.</p>");
